INTRODUCTION (#ulink_2c7a6815-3ebe-59aa-8609-1355031c4948)
PEOPLE LIVING IN BRITAIN and Ireland seldom have to travel far to find a wealth of wild flowers and, although the region’sv plantlife faces significant conservation issues, residents should feel privileged to live in such a flower-rich part of the world. Underpinning our floral diversity is a rich array of habitats, the product of our region’s topography, geology and history of land use. Good fortune, in the form of the Gulf Stream, dictates a mild and comparatively equable climate for much of the time, and this, too, contributes to botanical diversity. Complete British Wild Flowers has arisen from my personal love for the flora of Britain and Ireland, not to mention half a lifetime devoted to photographing our wild flowers.
THE REGION COVERED BY THIS BOOK
The region covered by this book comprises the whole of mainland England, Wales, Scotland and Ireland, as well as offshore islands including the Shetlands, Orkneys, Hebrides, Isle of Man and the Isles of Scilly. In addition, I have included the Channel Islands because their proximity to, and ecological affinities with, northern France allow them to make a valuable contribution to our flora.
THE CHOICE OF SPECIES
The coverage of the book is restricted mainly to what most people understand to be wild flowers – not a strict botanical term, but taken to mean flowering plants of relatively modest stature, species that in most cases do not exceed 2m in height. For the sake of completeness I have also included a number of woody flowering shrubs, but I have excluded obvious tree species. Terrestrial habitats harbour the lion’s share of our flowering plants and this is reflected in the coverage of this book. But I have also included species that are strictly aquatic, both those that occur in freshwater habitats and the limited range of flowering plants that grow in coastal marine environments.
Complete British Wild Flowers is aimed primarily at the botanical novice and those with a moderate degree of botanical experience. Consequently, for the main section of the book, I have selected species that the naturalist stands a reasonable chance of encountering, although a few scarce but spectacular and distinctive species have also been included here for good measure. Some botanical groups are minefields for the beginner: for example, hundreds of so-called ‘microspecies’ of brambles are recognised by experts and similar complexity is found among dandelions, hawkweeds and eyebrights to name three more. In a book of this size, accurate identification of these subdivisions is impossible to achieve. So rather than baffle the reader, I have chosen to ‘lump’ the subdivisions together within these complex groups and treat them as species aggregates.
In the hope and expectation that readers’ appetites for botanical discoveries are whetted by the book, the last section of Complete British Wild Flowers is devoted to botanical hotspots, areas that merit a visit in search of the localised floral treasures they harbour.
Floral delights such as this heathland have inspired generations of botanists.
HOW TO USE THIS BOOK (#ulink_5f20f9de-0193-5d54-8614-e6fc54dde81d)
THE BOOK HAS BEEN designed so that the text and photographs for each species are on facing pages. A system of labelling clearly states the flower’s identity. The text has been written to complement the information conveyed by the photographs. By and large, the order in which the species appear in the main section of the book roughly follows standard botanical classification. However, because parts of the field are in a state of flux, the order may differ slightly from that found in other guides, past, present or future.
SPECIES DESCRIPTIONS
At the start of each species description the plant’s most commonly used and current English name is given. This is followed by the scientific name, comprising the genus name first and then by the specific name. In a few instances, where this is pertinent, reference is made, in either the species heading or the main body of the text, to a further subdivision: subspecies. In general, I have followed the nomenclature of Clive Stace’s New Flora of the British Isles (seep (#litres_trial_promo).). However, with orchids I have used the most up-to-date classification system, which differs from that in most currently available floras. The family group to which the plant in question belongs is then given. If a species is anything other than widespread and common, there then follows a measure of its scarcity, indicated by rosette symbols:
These scarcity ratings are based on my own observations, so they are subjective and are not intended as an absolute guide to a species’ status. Lastly in the heading, some measure is given of the plant’s size. Size and stature vary according to a number of factors so these values should be treated with a degree of caution.
The text has been written in as concise a manner as possible. Each description begins with a summary of the plant and the habitat that it favours. To avoid potential ambiguities, the following headings break up the rest of each description: FLOWERS; FRUITS; LEAVES; STATUS. These sections describe the colour, shape and size of the various plant parts – features that tend to be more constant, and hence more useful for identification, than the overall size of the plant. Text in italics relates to key features of identification.
MAPS
The maps provide invaluable information about the distribution and occurrence of each species in the region: the intensity of the colour gives an indication of abundance. In compiling the maps, I have made reference to a number of sources, including An Atlas of the Wild Flowers of Britain and Northern Europe, the New Atlas of the British and Irish Flora (seep (#litres_trial_promo).), various county floras and, of course, my own notes. The maps represent the current ranges of plants in the region in general terms. Please bear in mind that, given the size of the maps, small and isolated populations will not necessarily be featured. Note also that the ranges of many species (particularly those influenced by agriculture) are likely to contract further as the years go by.
PHOTOGRAPHS
Great care has gone into the selection of photographs for this book and in many cases the images have been taken specifically for this project. Preference has been given to photographs that serve both to illustrate key identification features of a species when in flower, and to emphasise its beauty. In many instances, smaller inset photographs illustrate useful identification features that are not shown clearly by the main image.
BASIC BOTANY (#ulink_153f0816-1744-5895-8c86-b02e3b519feb)
IN COMMON WITH OTHER living organisms, plants have the abilities to grow, reproduce themselves, respond to stimuli and – to a limited extent compared to most animals – move. What sets them apart from animals in particular, and defines plants as a group, is their ability, in almost all species, to manufacture their own food from inorganic building blocks. Fundamental to this ability is the process called photosynthesis, in which plants use energy from sunlight to convert carbon dioxide from the air and water into glucose. Oxygen is a by-product of this reaction. A pigment called chlorophyll is the agent that extracts from sunlight the energy needed to fuel the reaction; its coloration is what makes plants green.
The plants covered in this book are the most advanced of their kind in evolutionary terms. All have the ability to reproduce sexually and flowers are the means by which this process is achieved. Flower structure is as varied as it is complex, and the fact that whole books, including this one, can be devoted to detailing its diversity is testament to this. Flower structure is dealt with in more detail on page 10.
Among terrestrial plants the process of photosynthesis is difficult to demonstrate outside the laboratory. However, certain submerged aquatic plants, such as this Water Starwort, produce bubbles of oxygen when they are exposed to bright sunlight, indicating that photosynthesis is indeed taking place.
THE ROLE OF PLANTS IN ECOLOGY
The importance of plants in the global ecosystem, and at the local level, cannot be overstated. Not only do plants generate (through photosynthesis) the atmospheric oxygen that all animals need to breathe but, as a source of food, they underpin food chains across the world. Without plants, life on earth as we know it would not have evolved and could not survive.
The survival of plants and animals is inextricably linked at the general level, but there are plenty of highly specific instances of dependence, the relationship often hinted at by their English names. Without their namesake-specific foodplants, neither the Figwort Weevil (left) nor the Mullein Moth (right), shown here as a caterpillar, could survive.

FLOWERS (#ulink_b80d4d04-ce56-509d-8fbd-ec0d0fbd038f)
ATTRACTIVE THOUGH MANY OF them may be, flowers are not produced to delight the human eye. Their role is strictly functional – they are the plant’s sex organs, there to produce sex cells and ensure the maximum chance of successful fertilisation taking place.
BASIC FLOWER STRUCTURE AND FUNCTION
In a few species, male and female sex cells are borne in separate flowers, or even on different plants, but in most cases they appear together within the same flower. Male sex cells are contained within pollen, tiny grains that are produced by structures called anthers and borne on slender stems referred to as filaments; collectively, anthers and filaments are referred to as stamens. The female part of most flowers comprises the ovary, containing the female sex cells, above which is borne the stigma (which receives the pollen) carried on a stem called the style.
Some plants, such as grasses and catkin-bearing shrubs, employ the wind to carry their pollen to others of the same species. Vast quantities of pollen are required to achieve a successful outcome with such a random process. Most other species adopt a more targeted approach and use the services of animals – insects in almost all cases – to transfer pollen. In exchange for a meal, in the form of nectar, insects inadvertently carry pollen on their bodies to the next flowers they visit; with any luck, a neighbouring plant of the same species will be visited while pollen still persists. In almost all species, flower structure has evolved to avoid self-pollination and to maximise the chances of cross-pollination – pollen being transferred to visiting insect pollinators and received from other plants by the same agents.
Bumblebees, and bees generally, are the classic insect pollinators. They visit flowers in search of nectar and unwittingly acquire a dusting of pollen, which is slightly sticky, on their hairy bodies; this is then carried to subsequent flowers they visit.

WILD FLOWER IDENTIFICATION (#ulink_4cbc75e7-23af-5bd4-9fc5-1ccc33da01e8)
SEASONED AND EXPERIENCED BOTANISTS are likely to approach the subject of identification by using definitive botanical works (floras) that rely on detailed keys, a thorough understanding of botanical terms, and a willingness to use descriptions rather than pictures to separate species. While this approach has scientific validity, in my experience it is not the way that the average floral enthusiast approaches the problem. Most tend to leaf through illustrated books to find suitable candidate species and then narrow down the field by scrutinising any closely related alternatives. This approach can succeed in most instances, especially if close care is paid to the detailed structure of the plant – leaves and fruits, as well as flowers – in addition to other factors such as flowering time, habitat preferences and distribution. I anticipate that this is how Complete British Wild Flowers will be used, initially at least, by most readers, although it will not take long for even the most inexperienced person to be able to detect similarities among plant family members, hence narrowing down the options at a stroke. Nevertheless, for absolute beginners, I felt it would be useful to provide a few pointers to lead in the right direction. I have concentrated on flower families where, in most species, there are sufficient similarities to justify generalisations. Strikingly unusual flowers, and species without large family ties, are not included in the following series of short cuts. I have used flower structure, such as the number of petals, as an initial guide. Note, however, that within several of the families identified, one or more rogue species may defy the family character and will not fall into the appropriate category. For example, although Tormentil is a member of the rose family (characterised by flowers with five petals), its flowers have just four petals.

FRUITS AND SEEDS (#ulink_bcf201fb-e280-575e-9608-9f9b33d6ae20)
FRUITS FOLLOW IN THE wake of flowers and are the structures in which a plant’s seeds develop and are protected. In many cases, the shape and structure of these fruits, and often the seeds themselves, are designed to assist their dispersal, when ripe, away from the plant that produced them. A number of ingenious methods have evolved to facilitate this process: some seeds are carried by the wind; others attach themselves to the fur of animals; some even float away on water or have evolved to be eaten and digested by birds. The study of fruits and seeds is not only fascinating in its own right but in many instances the structure or appearance of a fruit can be a valuable aid to correct identification.
The burred fruits of Lesser Burdock readily become snagged in animal fur, travelling with the creature until the fruit finally disintegrates and liberates the seeds.
The hook-tipped spines on the fruit of Wood Avens catch in animal fur. Subsequently, they also help the fruit to disintegrate, as unattached barbs snag on objects and material that the animal rubs against.
The flowers of Common and Grey Field-speedwells are rather similar. Only by looking at the fruits (Common left, Grey right) can you be absolutely certain of any given plant’s identity.
Cabbage family members produce fruits known as pods, which vary considerably in terms of size and shape according to species. Those of Wild Candytuft, seen here, are particularly attractive.
Dandelion seeds are armed with a tuft of hairs – the pappus – that assists wind dispersal. While it remains intact, the collection of seeds and hairs is often referred to as a ‘clock’.
The fruits of Field Gromwell are hard-cased nutlets, designed to be resistant to abrasion and wear, allowing the species to grow as an arable weed, but of course only in the absence of herbicides.
Like other members of the pea family, the fruits of bird’s-foottrefoil are elongated pods.
The seeds of Elder are contained within luscious berries. These are eaten by birds and the seeds (protected by a coating resistant to being digested) are dispersed with the droppings.
The fruits of roses are fleshy and known as hips; inside these are seeds (dry achenes).
The fruit of the Common Poppy is a hollow vessel that contains thousands of minute seeds. When the fruit is ripe, holes below its rim allow seeds to escape when the plant is shaken by the wind.
In strict botanical terms, the fruits of the Raspberry are a collection of small drupes – each one a fleshy fruit that contains a hard-coated seed.
LEAVES (#ulink_b826e93c-1cd7-56d0-bc3c-1b92555f1796)
BEING THE MAIN STRUCTURES responsible for photosynthesis, a plant’s leaves are its powerhouse. They vary from species to species and come in a wide range of shapes and sizes. Their appearance is an evolutionary response to the plant’s needs, in particular factors such as the habitat in which it grows, the degree of shading or exposure dictated by its favoured growing location, and rainfall. In most instances, all the leaves on a given plant are likely to be broadly similar to one another, although size tends to decrease up the stem of a plant. However, to complicate matters, basal leaves can be entirely different in appearance from stem leaves. This applies to a number of species, notably some umbellifers.
In essence, leaves are thin and rather delicate structures. However, rigidity is maintained by a network of veins through which pass the ingredients required for photosynthesis, and the products of the process.
The intricate network of veins in a leaf is often best appreciated after autumn leaf-fall in deciduous species. Softer tissue decomposes before the veins themselves disintegrate, leaving striking leaf skeletons.
Leaf shape is not an infallible guide to plant identity, so its importance as an identifying feature is secondary to the appearance of flowers. There are many instances where entirely unrelated plants have superficially very similar leaves and great care must be taken when using leaf shape alone for identification. However, there are also plenty of instances where leaf shape is distinctive and diagnostic, or where it allows the separation of closely related plants that have superficially similar flowers. So it is worth paying attention to the variety of leaf shapes found among British wild flowers, some of which are shown right and overleaf along with the common descriptive name by which their shapes are known. Also shown are a variety of distinctive marginal features.

HABITATS (#ulink_664f33cb-f648-5edc-a4b1-cc0c22ddb6c7)
WHEREVER CONDITIONS ARE SUITABLE for life then plants are likely to grow. Although some species are rather catholic with regard to where they grow, most are much more specific, influenced by factors such as underlying soil type, whether the soil is waterlogged or free-draining, summer and winter temperature extremes and so on. Consequently, where environmental conditions are broadly similar, the same plant species are likely to be found; where these communities are recognisably distinct they are referred to by specific habitat names. In Britain, many of our most distinct habitats owe their existence to past and present human activity, so they are classed as semi-natural in ecological terms.
DECIDUOUS WOODLAND
Woodlands of deciduous trees are found throughout most of the region. They are (or would be, if allowed to flourish) the dominant natural forest type of all regions except in parts of Scotland where evergreen conifers predominate. As their name suggests, deciduous trees have shed their leaves by winter and grow a new set the following spring. The seasonality seen in deciduous woodland is among the most marked and easily observed of any habitat in the region.
Almost all woodland in the region has been, and still is, influenced in some way by man. This might take the form of simple disturbance by walkers, at one end of the spectrum, or clear-felling at the other. Man’s influence is not always to the detriment of wildlife, however. Sympathetic coppicing of Hazel and Ash, for example, can encourage a profusion of wild flowers. In particularly rich locations, carpets of Bluebells, Wood Anemones and Wood Sorrel form the backdrop for more unusual species such as Early Purple Orchid and Greater Butterfly Orchid, Goldilocks Buttercup and Herb-Paris.
Centuries of woodland coppicing have inadvertently created the perfect environment for Bluebells to thrive. A carpet of these lovely plants is a quintessentially English scene.
CONIFEROUS WOODLAND
Areas of native conifer woodland are restricted to a few relict pockets of Caledonian pine forest in the Highlands of Scotland. Conifers that are seen almost everywhere else in Britain and Ireland have either been planted or have seeded themselves from mature plantations. Our native conifer forests harbour an intriguing selection of plants, such as various wintergreen species, Twinflower and Creeping Lady’s-tresses, but conifer plantations are usually species-poor.
HEDGEROWS AND SCRUB
Once so much a feature of the British countryside, hedgerows have suffered a dramatic decline in recent decades. Many hedgerows have either been grubbed out by farmers keen to expand arable field sizes or, more insidiously, wrecked – both in terms of appearance and in their value to wildlife – by inappropriate cutting regimes.
The extent of scrub in the landscape has also diminished in recent times. Although scrub is difficult to define in strict habitat terms, most people would understand the word to mean a loose assemblage of tangled, medium-sized shrubs and bushes interspersed with patches of spreading plants such as Bramble and areas of grassland. Scrub is frequently despised by landowners – sometimes even by naturalists too – but its value to many species formerly considered so common and widespread as not to merit conservation attention should not be underestimated.
Hedgerows usually comprise the species, and acquire the character, of any woodland edge in the vicinity. Scrub, too, reflects the botanical composition of the surrounding area. However, because scrub is essentially a colonising habitat, and not an established one, the bushes and shrubs that comprise tend to be those that grow the fastest.
GRASSLAND AND FARMLAND
Full of wild flowers and native grass species, a good grassy meadow is a delight to anyone with an eye for colour and an interest in natural history. Unfortunately, prime sites are comparatively few and far between these days, either lost to the plough or ‘improved’ by farmers for grazing, by seeding with fast-growing, non-native grass species and by applying selective herbicides. When this happens, the grassland loses its intrinsic botanical interest and value.
It should not be forgotten that, in Britain and Ireland, grassland is a man-made habitat, the result of woodland clearance for grazing in centuries past. If a site is to be maintained as grassland, continued grazing or cutting is needed to ensure that scrub does not regenerate. In the past, the way in which grassland was managed had the beneficial side-effect – from a naturalists’ perspective – of increasing botanical diversity. Under modern ‘efficient’ farming regimes the reverse is the case.
Although arable fields may fall loosely into the category of grasslands (crop species such as wheat, barley and oats are grasses after all), their botanical interest tends to be minimal in many areas. Modern herbicides ensure that ‘weeds’ are kept to a minimum, and decades of chemical use have resulted in the soil’s seed bank being depleted dramatically. Many of the more delicate arable ‘weed’ species are essentially things of the past, often relegated to a few scraps of marginal land that escape spraying either by luck or, in a few instances, through the foresight of farmers. Arable weeds depend on disturbance, being unable to compete in stable grassland communities. So there is a sad irony to the fact that grant-funded ‘conservation’ schemes that create wildlife ‘headlands’ are often the final nail in the coffin for these scarce species, which become crowded out by the vigorous growth of seeded rank grasses and clovers.
HEATHLAND
Heathlands are essentially restricted to southern England, with the majority of sites concentrated in Surrey, Hampshire and Dorset. However, further isolated examples of heath-land can be found further afield, in south Devon and Suffolk, for example, and in coastal districts of Cornwall and Pembrokeshire. This fragmented distribution adds to the problems that beset the habitat: ‘island’ populations of plants and animals have little chance of receiving genetic input from other sites.
Heathland owes its existence to man, and came about following forest clearance on acid, sandy soils. Regimes of grazing, cutting and periodic burning in the past have helped maintain heathland, and continued management is needed to ensure an appropriate balance between scrub encroachment and the maintenance of an open habitat. Ironically, man is also the biggest threat to the habitat: uncontrolled burns cause damage that takes decades or more to repair, while the destruction of heathland for housing developments obviously means the loss of this unique habitat for good.
The habitat’s name is clearly derived from the presence, and often dominance, of members of the heath family of plants, all of which flourish on acid soils. For the ultimate visual display, visit an area of heathland in July, August and September when these plants are in full bloom.
UPLANDS
Together with more remote stretches of coastline, upland areas are perhaps the only parts of our region to retain a sense of isolation for the visitor. Many of these places appear wild and untamed, although in reality this is often just an illusion: few areas can be said to be truly pristine.
In centuries gone by, all but the highest peaks would have been wooded. Clearance of trees and subsequent, often excessive, grazing by sheep ensured that the natural woodland disappeared and cannot regenerate. In general terms, moorland is the dominant habitat in upland areas although the characteristic plants and appearance vary considerably from region to region, and are profoundly influenced by soil type and climate; communities dominated by Heather or moorland grass species form the two extremes. In a few areas, mountains dominate the landscape, sometimes rising to altitudes above the level at which trees would grow if they were allowed to do so; these areas harbour unique communities of plants, many restricted to rocky gullies and crags that escape nibbling by sheep. Highlights include Moss Campion and an intriguing range of saxifrage species.
FRESHWATER HABITATS
Freshwater habitats have the same magnetic appeal as coastal habitats. In Britain and Ireland, we are indeed fortunate in having a wealth of examples, from small ponds and streams to large lakes and river systems; few people have to travel excessive distances to visit one or more of these habitats.
Flowing water has a charm all of its own and a trip to a river or stream will invariably yield discoveries of showy marginal species such as Yellow Iris and Ragged Robin, while specialised aquatic plants flourish in areas where the water is not too polluted.
Bodies of standing water often harbour a strikingly different range of plants from those found in flowing water. Many seemingly natural lakes are man-made, or at least man-influenced, and within this category fall flooded gravel pits, and more obviously, reservoirs and canals. By mid summer a rich growth of aquatic plants, such as pondweed species, dominates many of our smaller ponds as well as the margins of lakes. Pond and lake margins are fascinating places for the botanist to explore, with bur-marigold species, Golden Dock, Mudwort and Six-stamened Waterwort among the highlights. Left to their own devices, the margins are soon encroached by stands of more robust emergent plants, and species such as Common Reed sometimes form extensive beds around larger lakes.
The encroachment of vegetation into areas of open water leads to the creation of habitats know as mires, which are more popularly referred to in a general context as marshes. Marshes often form on neutral soils, but where they are base-rich (alkaline) then the resultant habitat is called a fen. Conversely, acid soils encourage the formation of bogs. The nature of the underlying soil has a profound influence not only on the appearance of the mire in question but also on the plant species that grow there. Some wetland plants, such as Bogbean, will grow in both moderately acid and mildly alkaline conditions while others are more selective. Thus, for example, we find that certain plants, such as cotton-grasses, sundews and butterworts, are essentially restricted to acid soils while fens are home to a range of interesting sedges, plus more showy plants including Great Meadow-rue, Marsh Valerian, Marsh Pea and Greater Water-parsnip.
COASTAL HABITATS
In habitat terms the coastline is arguably Great Britain’s crowning glory. Although development has marred some areas, particularly in southern England, those that remain unspoilt there, and elsewhere in Britain and Ireland, are truly wonderful and harbour a rich array of specialised plants.
For breathtaking scenery and a sense of untamed nature, coastal cliffs offer unrivalled opportunities for the naturalist. Botanical highlights include carpets of Thrift that dominate the vegetation in many western parts of the region, with species such as Sea Carrot, Sea Campion and various sea-spurreys in attendance.
To the unenlightened eye, an estuary may seem like a vast expanse of mudflats, studded with a mosaic of bedraggled-looking vegetation and very little else. For the botanist, however, nothing could be further from the truth. Specialised plants including glassworts, sea-lavenders and Sea Purslane have evolved to cope with twice-daily inundation by sea water. Above the high tideline, intriguing salt-tolerant species thrive.
Portland Spurge is just one of the delights to greet visiting botanists on a spring trip to the extensive dune system of Braunton Burrows in Devon.
Sandy shores are beloved of holidaymakers but have much to offer the botanist too. On the landward side of the beach, colonising plants – notably Marram Grass – establish stable dune systems and subsequently these are colonised by maritime plants such as Sea Spurge as well as grassland species such as Viper’s-bugloss and Common Bird’s-foot-trefoil. Coastal shingle is a more challenging environment for a plant and it tends to be the domain of hardy specialists such as Sea-holly, Yellow Horned-poppy and Sea-kale.
In botanical terms, the stabilised shingle at Chesil Beach in Dorset is arguably the finest of its kind in Europe. Here, extensive carpets of Horseshoe Vetch can be seen, but Bird’s-foot-trefoil and Thrift also thrive in abundance.
CONSERVATION (#ulink_194bbfd8-0e63-5cc3-b909-7fd5ccbac5c6)
WORKING ON THIS PROJECT gave me the opportunity to visit many wonderful botanical locations across our region, the best of which are protected, to a degree, by nature reserve status and hence are still in good order. I also revisited many unprotected wayside botanical sites that I had not seen for several years. Sadly, most had become botanically impoverished and some had even lost the special plants for which they had been known. It will come as no surprise to learn that the majority of these sites were on areas of farmland.
WHAT’S GONE WRONG?
Threats to the countryside are all too obvious these days: the swallowing of land for housing, road schemes and the like, industrial and domestic pollution, and above all changes in agricultural practices – namely the unquestioning use of ever-more ‘efficient’ herbicides since the 1950s. And problems for wild flowers in the countryside do not stop with farming. Many landowners view the land they own as something to be exploited, if not for economic gain then as a playground, without a thought for conservation.
It has come to something when the discovery of Spreading Hedge-parsley, once a widespread arable ‘weed’, is a cause for botanical celebration. Without changes in agricultural practices, species such as this – already extinct at a local level in many areas – could disappear from Britain completely.
WHAT CAN BE DONE?
Legislation and agricultural grants relating to the way the countryside is managed need to target wildlife more intelligently than is currently the case, and development and change of land use should be subject to as much restriction as exists in the world of town planning. Easy to say, but much harder to put into practice. And there seems little cause for optimism, given that statutory bodies commanded with the responsibility for nature conservation are funded by government, itself perceived as being more receptive to economic than to environmental lobbies.
WHAT CAN YOU DO?
Object to, and oppose, all major development in the countryside and support organisations that are critical of the way intensive farming and insidious urbanisation have changed the botanical face of the landscape. On a small scale, grow as much of your own food as you can, garden organically, and use local organic sources for your additional needs whenever possible. Another way that the individual can help safeguard the British countryside is to donate as much money as possible to conservation organisations for the purchase of land to remove it from the threat of intensive farming or development. Suitable recipients of donations would include organisations such as Plantlife International, the various county Wildlife Trusts, the Woodland Trust, the National Trust and the RSPB.
Although walks in the countryside sometimes induce a sense of gloomy pessimism, budding botanists should not despair. Remarkably few flowering plant species have been lost entirely from Britain and Ireland in the last century and there are still plenty of wonderful botanically rich locations around the country. Nature reserves are thriving and, with your support and enthusiasm, things can only get better.
Thankfully, it is still possible to find agricultural fields where Cornflowers and other arable weeds thrive alongside the desired crop plant, either by design or where non-intensive farming methods are used. Let us hope that sights such as this become more commonplace as enlightenment, or financial inducements, change the way some of the land is farmed.

INTRODUCTION (#ulink_2c7a6815-3ebe-59aa-8609-1355031c4948)
PEOPLE LIVING IN BRITAIN and Ireland seldom have to travel far to find a wealth of wild flowers and, although the region’sv plantlife faces significant conservation issues, residents should feel privileged to live in such a flower-rich part of the world. Underpinning our floral diversity is a rich array of habitats, the product of our region’s topography, geology and history of land use. Good fortune, in the form of the Gulf Stream, dictates a mild and comparatively equable climate for much of the time, and this, too, contributes to botanical diversity. Complete British Wild Flowers has arisen from my personal love for the flora of Britain and Ireland, not to mention half a lifetime devoted to photographing our wild flowers.
THE REGION COVERED BY THIS BOOK
The region covered by this book comprises the whole of mainland England, Wales, Scotland and Ireland, as well as offshore islands including the Shetlands, Orkneys, Hebrides, Isle of Man and the Isles of Scilly. In addition, I have included the Channel Islands because their proximity to, and ecological affinities with, northern France allow them to make a valuable contribution to our flora.
THE CHOICE OF SPECIES
The coverage of the book is restricted mainly to what most people understand to be wild flowers – not a strict botanical term, but taken to mean flowering plants of relatively modest stature, species that in most cases do not exceed 2m in height. For the sake of completeness I have also included a number of woody flowering shrubs, but I have excluded obvious tree species. Terrestrial habitats harbour the lion’s share of our flowering plants and this is reflected in the coverage of this book. But I have also included species that are strictly aquatic, both those that occur in freshwater habitats and the limited range of flowering plants that grow in coastal marine environments.
Complete British Wild Flowers is aimed primarily at the botanical novice and those with a moderate degree of botanical experience. Consequently, for the main section of the book, I have selected species that the naturalist stands a reasonable chance of encountering, although a few scarce but spectacular and distinctive species have also been included here for good measure. Some botanical groups are minefields for the beginner: for example, hundreds of so-called ‘microspecies’ of brambles are recognised by experts and similar complexity is found among dandelions, hawkweeds and eyebrights to name three more. In a book of this size, accurate identification of these subdivisions is impossible to achieve. So rather than baffle the reader, I have chosen to ‘lump’ the subdivisions together within these complex groups and treat them as species aggregates.
In the hope and expectation that readers’ appetites for botanical discoveries are whetted by the book, the last section of Complete British Wild Flowers is devoted to botanical hotspots, areas that merit a visit in search of the localised floral treasures they harbour.
Floral delights such as this heathland have inspired generations of botanists.
HOW TO USE THIS BOOK (#ulink_5f20f9de-0193-5d54-8614-e6fc54dde81d)
THE BOOK HAS BEEN designed so that the text and photographs for each species are on facing pages. A system of labelling clearly states the flower’s identity. The text has been written to complement the information conveyed by the photographs. By and large, the order in which the species appear in the main section of the book roughly follows standard botanical classification. However, because parts of the field are in a state of flux, the order may differ slightly from that found in other guides, past, present or future.
SPECIES DESCRIPTIONS
At the start of each species description the plant’s most commonly used and current English name is given. This is followed by the scientific name, comprising the genus name first and then by the specific name. In a few instances, where this is pertinent, reference is made, in either the species heading or the main body of the text, to a further subdivision: subspecies. In general, I have followed the nomenclature of Clive Stace’s New Flora of the British Isles (seep (#litres_trial_promo).). However, with orchids I have used the most up-to-date classification system, which differs from that in most currently available floras. The family group to which the plant in question belongs is then given. If a species is anything other than widespread and common, there then follows a measure of its scarcity, indicated by rosette symbols:
These scarcity ratings are based on my own observations, so they are subjective and are not intended as an absolute guide to a species’ status. Lastly in the heading, some measure is given of the plant’s size. Size and stature vary according to a number of factors so these values should be treated with a degree of caution.
The text has been written in as concise a manner as possible. Each description begins with a summary of the plant and the habitat that it favours. To avoid potential ambiguities, the following headings break up the rest of each description: FLOWERS; FRUITS; LEAVES; STATUS. These sections describe the colour, shape and size of the various plant parts – features that tend to be more constant, and hence more useful for identification, than the overall size of the plant. Text in italics relates to key features of identification.
MAPS
The maps provide invaluable information about the distribution and occurrence of each species in the region: the intensity of the colour gives an indication of abundance. In compiling the maps, I have made reference to a number of sources, including An Atlas of the Wild Flowers of Britain and Northern Europe, the New Atlas of the British and Irish Flora (seep (#litres_trial_promo).), various county floras and, of course, my own notes. The maps represent the current ranges of plants in the region in general terms. Please bear in mind that, given the size of the maps, small and isolated populations will not necessarily be featured. Note also that the ranges of many species (particularly those influenced by agriculture) are likely to contract further as the years go by.
PHOTOGRAPHS
Great care has gone into the selection of photographs for this book and in many cases the images have been taken specifically for this project. Preference has been given to photographs that serve both to illustrate key identification features of a species when in flower, and to emphasise its beauty. In many instances, smaller inset photographs illustrate useful identification features that are not shown clearly by the main image.
BASIC BOTANY (#ulink_153f0816-1744-5895-8c86-b02e3b519feb)
IN COMMON WITH OTHER living organisms, plants have the abilities to grow, reproduce themselves, respond to stimuli and – to a limited extent compared to most animals – move. What sets them apart from animals in particular, and defines plants as a group, is their ability, in almost all species, to manufacture their own food from inorganic building blocks. Fundamental to this ability is the process called photosynthesis, in which plants use energy from sunlight to convert carbon dioxide from the air and water into glucose. Oxygen is a by-product of this reaction. A pigment called chlorophyll is the agent that extracts from sunlight the energy needed to fuel the reaction; its coloration is what makes plants green.
The plants covered in this book are the most advanced of their kind in evolutionary terms. All have the ability to reproduce sexually and flowers are the means by which this process is achieved. Flower structure is as varied as it is complex, and the fact that whole books, including this one, can be devoted to detailing its diversity is testament to this. Flower structure is dealt with in more detail on page 10.
Among terrestrial plants the process of photosynthesis is difficult to demonstrate outside the laboratory. However, certain submerged aquatic plants, such as this Water Starwort, produce bubbles of oxygen when they are exposed to bright sunlight, indicating that photosynthesis is indeed taking place.
THE ROLE OF PLANTS IN ECOLOGY
The importance of plants in the global ecosystem, and at the local level, cannot be overstated. Not only do plants generate (through photosynthesis) the atmospheric oxygen that all animals need to breathe but, as a source of food, they underpin food chains across the world. Without plants, life on earth as we know it would not have evolved and could not survive.
The survival of plants and animals is inextricably linked at the general level, but there are plenty of highly specific instances of dependence, the relationship often hinted at by their English names. Without their namesake-specific foodplants, neither the Figwort Weevil (left) nor the Mullein Moth (right), shown here as a caterpillar, could survive.

FLOWERS (#ulink_b80d4d04-ce56-509d-8fbd-ec0d0fbd038f)
ATTRACTIVE THOUGH MANY OF them may be, flowers are not produced to delight the human eye. Their role is strictly functional – they are the plant’s sex organs, there to produce sex cells and ensure the maximum chance of successful fertilisation taking place.
BASIC FLOWER STRUCTURE AND FUNCTION
In a few species, male and female sex cells are borne in separate flowers, or even on different plants, but in most cases they appear together within the same flower. Male sex cells are contained within pollen, tiny grains that are produced by structures called anthers and borne on slender stems referred to as filaments; collectively, anthers and filaments are referred to as stamens. The female part of most flowers comprises the ovary, containing the female sex cells, above which is borne the stigma (which receives the pollen) carried on a stem called the style.
Some plants, such as grasses and catkin-bearing shrubs, employ the wind to carry their pollen to others of the same species. Vast quantities of pollen are required to achieve a successful outcome with such a random process. Most other species adopt a more targeted approach and use the services of animals – insects in almost all cases – to transfer pollen. In exchange for a meal, in the form of nectar, insects inadvertently carry pollen on their bodies to the next flowers they visit; with any luck, a neighbouring plant of the same species will be visited while pollen still persists. In almost all species, flower structure has evolved to avoid self-pollination and to maximise the chances of cross-pollination – pollen being transferred to visiting insect pollinators and received from other plants by the same agents.
Bumblebees, and bees generally, are the classic insect pollinators. They visit flowers in search of nectar and unwittingly acquire a dusting of pollen, which is slightly sticky, on their hairy bodies; this is then carried to subsequent flowers they visit.

WILD FLOWER IDENTIFICATION (#ulink_4cbc75e7-23af-5bd4-9fc5-1ccc33da01e8)
SEASONED AND EXPERIENCED BOTANISTS are likely to approach the subject of identification by using definitive botanical works (floras) that rely on detailed keys, a thorough understanding of botanical terms, and a willingness to use descriptions rather than pictures to separate species. While this approach has scientific validity, in my experience it is not the way that the average floral enthusiast approaches the problem. Most tend to leaf through illustrated books to find suitable candidate species and then narrow down the field by scrutinising any closely related alternatives. This approach can succeed in most instances, especially if close care is paid to the detailed structure of the plant – leaves and fruits, as well as flowers – in addition to other factors such as flowering time, habitat preferences and distribution. I anticipate that this is how Complete British Wild Flowers will be used, initially at least, by most readers, although it will not take long for even the most inexperienced person to be able to detect similarities among plant family members, hence narrowing down the options at a stroke. Nevertheless, for absolute beginners, I felt it would be useful to provide a few pointers to lead in the right direction. I have concentrated on flower families where, in most species, there are sufficient similarities to justify generalisations. Strikingly unusual flowers, and species without large family ties, are not included in the following series of short cuts. I have used flower structure, such as the number of petals, as an initial guide. Note, however, that within several of the families identified, one or more rogue species may defy the family character and will not fall into the appropriate category. For example, although Tormentil is a member of the rose family (characterised by flowers with five petals), its flowers have just four petals.

FRUITS AND SEEDS (#ulink_bcf201fb-e280-575e-9608-9f9b33d6ae20)
FRUITS FOLLOW IN THE wake of flowers and are the structures in which a plant’s seeds develop and are protected. In many cases, the shape and structure of these fruits, and often the seeds themselves, are designed to assist their dispersal, when ripe, away from the plant that produced them. A number of ingenious methods have evolved to facilitate this process: some seeds are carried by the wind; others attach themselves to the fur of animals; some even float away on water or have evolved to be eaten and digested by birds. The study of fruits and seeds is not only fascinating in its own right but in many instances the structure or appearance of a fruit can be a valuable aid to correct identification.
The burred fruits of Lesser Burdock readily become snagged in animal fur, travelling with the creature until the fruit finally disintegrates and liberates the seeds.
The hook-tipped spines on the fruit of Wood Avens catch in animal fur. Subsequently, they also help the fruit to disintegrate, as unattached barbs snag on objects and material that the animal rubs against.
The flowers of Common and Grey Field-speedwells are rather similar. Only by looking at the fruits (Common left, Grey right) can you be absolutely certain of any given plant’s identity.
Cabbage family members produce fruits known as pods, which vary considerably in terms of size and shape according to species. Those of Wild Candytuft, seen here, are particularly attractive.
Dandelion seeds are armed with a tuft of hairs – the pappus – that assists wind dispersal. While it remains intact, the collection of seeds and hairs is often referred to as a ‘clock’.
The fruits of Field Gromwell are hard-cased nutlets, designed to be resistant to abrasion and wear, allowing the species to grow as an arable weed, but of course only in the absence of herbicides.
Like other members of the pea family, the fruits of bird’s-foottrefoil are elongated pods.
The seeds of Elder are contained within luscious berries. These are eaten by birds and the seeds (protected by a coating resistant to being digested) are dispersed with the droppings.
The fruits of roses are fleshy and known as hips; inside these are seeds (dry achenes).
The fruit of the Common Poppy is a hollow vessel that contains thousands of minute seeds. When the fruit is ripe, holes below its rim allow seeds to escape when the plant is shaken by the wind.
In strict botanical terms, the fruits of the Raspberry are a collection of small drupes – each one a fleshy fruit that contains a hard-coated seed.
LEAVES (#ulink_b826e93c-1cd7-56d0-bc3c-1b92555f1796)
BEING THE MAIN STRUCTURES responsible for photosynthesis, a plant’s leaves are its powerhouse. They vary from species to species and come in a wide range of shapes and sizes. Their appearance is an evolutionary response to the plant’s needs, in particular factors such as the habitat in which it grows, the degree of shading or exposure dictated by its favoured growing location, and rainfall. In most instances, all the leaves on a given plant are likely to be broadly similar to one another, although size tends to decrease up the stem of a plant. However, to complicate matters, basal leaves can be entirely different in appearance from stem leaves. This applies to a number of species, notably some umbellifers.
In essence, leaves are thin and rather delicate structures. However, rigidity is maintained by a network of veins through which pass the ingredients required for photosynthesis, and the products of the process.
The intricate network of veins in a leaf is often best appreciated after autumn leaf-fall in deciduous species. Softer tissue decomposes before the veins themselves disintegrate, leaving striking leaf skeletons.
Leaf shape is not an infallible guide to plant identity, so its importance as an identifying feature is secondary to the appearance of flowers. There are many instances where entirely unrelated plants have superficially very similar leaves and great care must be taken when using leaf shape alone for identification. However, there are also plenty of instances where leaf shape is distinctive and diagnostic, or where it allows the separation of closely related plants that have superficially similar flowers. So it is worth paying attention to the variety of leaf shapes found among British wild flowers, some of which are shown right and overleaf along with the common descriptive name by which their shapes are known. Also shown are a variety of distinctive marginal features.

HABITATS (#ulink_664f33cb-f648-5edc-a4b1-cc0c22ddb6c7)
WHEREVER CONDITIONS ARE SUITABLE for life then plants are likely to grow. Although some species are rather catholic with regard to where they grow, most are much more specific, influenced by factors such as underlying soil type, whether the soil is waterlogged or free-draining, summer and winter temperature extremes and so on. Consequently, where environmental conditions are broadly similar, the same plant species are likely to be found; where these communities are recognisably distinct they are referred to by specific habitat names. In Britain, many of our most distinct habitats owe their existence to past and present human activity, so they are classed as semi-natural in ecological terms.
DECIDUOUS WOODLAND
Woodlands of deciduous trees are found throughout most of the region. They are (or would be, if allowed to flourish) the dominant natural forest type of all regions except in parts of Scotland where evergreen conifers predominate. As their name suggests, deciduous trees have shed their leaves by winter and grow a new set the following spring. The seasonality seen in deciduous woodland is among the most marked and easily observed of any habitat in the region.
Almost all woodland in the region has been, and still is, influenced in some way by man. This might take the form of simple disturbance by walkers, at one end of the spectrum, or clear-felling at the other. Man’s influence is not always to the detriment of wildlife, however. Sympathetic coppicing of Hazel and Ash, for example, can encourage a profusion of wild flowers. In particularly rich locations, carpets of Bluebells, Wood Anemones and Wood Sorrel form the backdrop for more unusual species such as Early Purple Orchid and Greater Butterfly Orchid, Goldilocks Buttercup and Herb-Paris.
Centuries of woodland coppicing have inadvertently created the perfect environment for Bluebells to thrive. A carpet of these lovely plants is a quintessentially English scene.
CONIFEROUS WOODLAND
Areas of native conifer woodland are restricted to a few relict pockets of Caledonian pine forest in the Highlands of Scotland. Conifers that are seen almost everywhere else in Britain and Ireland have either been planted or have seeded themselves from mature plantations. Our native conifer forests harbour an intriguing selection of plants, such as various wintergreen species, Twinflower and Creeping Lady’s-tresses, but conifer plantations are usually species-poor.
HEDGEROWS AND SCRUB
Once so much a feature of the British countryside, hedgerows have suffered a dramatic decline in recent decades. Many hedgerows have either been grubbed out by farmers keen to expand arable field sizes or, more insidiously, wrecked – both in terms of appearance and in their value to wildlife – by inappropriate cutting regimes.
The extent of scrub in the landscape has also diminished in recent times. Although scrub is difficult to define in strict habitat terms, most people would understand the word to mean a loose assemblage of tangled, medium-sized shrubs and bushes interspersed with patches of spreading plants such as Bramble and areas of grassland. Scrub is frequently despised by landowners – sometimes even by naturalists too – but its value to many species formerly considered so common and widespread as not to merit conservation attention should not be underestimated.
Hedgerows usually comprise the species, and acquire the character, of any woodland edge in the vicinity. Scrub, too, reflects the botanical composition of the surrounding area. However, because scrub is essentially a colonising habitat, and not an established one, the bushes and shrubs that comprise tend to be those that grow the fastest.
GRASSLAND AND FARMLAND
Full of wild flowers and native grass species, a good grassy meadow is a delight to anyone with an eye for colour and an interest in natural history. Unfortunately, prime sites are comparatively few and far between these days, either lost to the plough or ‘improved’ by farmers for grazing, by seeding with fast-growing, non-native grass species and by applying selective herbicides. When this happens, the grassland loses its intrinsic botanical interest and value.
It should not be forgotten that, in Britain and Ireland, grassland is a man-made habitat, the result of woodland clearance for grazing in centuries past. If a site is to be maintained as grassland, continued grazing or cutting is needed to ensure that scrub does not regenerate. In the past, the way in which grassland was managed had the beneficial side-effect – from a naturalists’ perspective – of increasing botanical diversity. Under modern ‘efficient’ farming regimes the reverse is the case.
Although arable fields may fall loosely into the category of grasslands (crop species such as wheat, barley and oats are grasses after all), their botanical interest tends to be minimal in many areas. Modern herbicides ensure that ‘weeds’ are kept to a minimum, and decades of chemical use have resulted in the soil’s seed bank being depleted dramatically. Many of the more delicate arable ‘weed’ species are essentially things of the past, often relegated to a few scraps of marginal land that escape spraying either by luck or, in a few instances, through the foresight of farmers. Arable weeds depend on disturbance, being unable to compete in stable grassland communities. So there is a sad irony to the fact that grant-funded ‘conservation’ schemes that create wildlife ‘headlands’ are often the final nail in the coffin for these scarce species, which become crowded out by the vigorous growth of seeded rank grasses and clovers.
HEATHLAND
Heathlands are essentially restricted to southern England, with the majority of sites concentrated in Surrey, Hampshire and Dorset. However, further isolated examples of heath-land can be found further afield, in south Devon and Suffolk, for example, and in coastal districts of Cornwall and Pembrokeshire. This fragmented distribution adds to the problems that beset the habitat: ‘island’ populations of plants and animals have little chance of receiving genetic input from other sites.
Heathland owes its existence to man, and came about following forest clearance on acid, sandy soils. Regimes of grazing, cutting and periodic burning in the past have helped maintain heathland, and continued management is needed to ensure an appropriate balance between scrub encroachment and the maintenance of an open habitat. Ironically, man is also the biggest threat to the habitat: uncontrolled burns cause damage that takes decades or more to repair, while the destruction of heathland for housing developments obviously means the loss of this unique habitat for good.
The habitat’s name is clearly derived from the presence, and often dominance, of members of the heath family of plants, all of which flourish on acid soils. For the ultimate visual display, visit an area of heathland in July, August and September when these plants are in full bloom.
UPLANDS
Together with more remote stretches of coastline, upland areas are perhaps the only parts of our region to retain a sense of isolation for the visitor. Many of these places appear wild and untamed, although in reality this is often just an illusion: few areas can be said to be truly pristine.
In centuries gone by, all but the highest peaks would have been wooded. Clearance of trees and subsequent, often excessive, grazing by sheep ensured that the natural woodland disappeared and cannot regenerate. In general terms, moorland is the dominant habitat in upland areas although the characteristic plants and appearance vary considerably from region to region, and are profoundly influenced by soil type and climate; communities dominated by Heather or moorland grass species form the two extremes. In a few areas, mountains dominate the landscape, sometimes rising to altitudes above the level at which trees would grow if they were allowed to do so; these areas harbour unique communities of plants, many restricted to rocky gullies and crags that escape nibbling by sheep. Highlights include Moss Campion and an intriguing range of saxifrage species.
FRESHWATER HABITATS
Freshwater habitats have the same magnetic appeal as coastal habitats. In Britain and Ireland, we are indeed fortunate in having a wealth of examples, from small ponds and streams to large lakes and river systems; few people have to travel excessive distances to visit one or more of these habitats.
Flowing water has a charm all of its own and a trip to a river or stream will invariably yield discoveries of showy marginal species such as Yellow Iris and Ragged Robin, while specialised aquatic plants flourish in areas where the water is not too polluted.
Bodies of standing water often harbour a strikingly different range of plants from those found in flowing water. Many seemingly natural lakes are man-made, or at least man-influenced, and within this category fall flooded gravel pits, and more obviously, reservoirs and canals. By mid summer a rich growth of aquatic plants, such as pondweed species, dominates many of our smaller ponds as well as the margins of lakes. Pond and lake margins are fascinating places for the botanist to explore, with bur-marigold species, Golden Dock, Mudwort and Six-stamened Waterwort among the highlights. Left to their own devices, the margins are soon encroached by stands of more robust emergent plants, and species such as Common Reed sometimes form extensive beds around larger lakes.
The encroachment of vegetation into areas of open water leads to the creation of habitats know as mires, which are more popularly referred to in a general context as marshes. Marshes often form on neutral soils, but where they are base-rich (alkaline) then the resultant habitat is called a fen. Conversely, acid soils encourage the formation of bogs. The nature of the underlying soil has a profound influence not only on the appearance of the mire in question but also on the plant species that grow there. Some wetland plants, such as Bogbean, will grow in both moderately acid and mildly alkaline conditions while others are more selective. Thus, for example, we find that certain plants, such as cotton-grasses, sundews and butterworts, are essentially restricted to acid soils while fens are home to a range of interesting sedges, plus more showy plants including Great Meadow-rue, Marsh Valerian, Marsh Pea and Greater Water-parsnip.
COASTAL HABITATS
In habitat terms the coastline is arguably Great Britain’s crowning glory. Although development has marred some areas, particularly in southern England, those that remain unspoilt there, and elsewhere in Britain and Ireland, are truly wonderful and harbour a rich array of specialised plants.
For breathtaking scenery and a sense of untamed nature, coastal cliffs offer unrivalled opportunities for the naturalist. Botanical highlights include carpets of Thrift that dominate the vegetation in many western parts of the region, with species such as Sea Carrot, Sea Campion and various sea-spurreys in attendance.
To the unenlightened eye, an estuary may seem like a vast expanse of mudflats, studded with a mosaic of bedraggled-looking vegetation and very little else. For the botanist, however, nothing could be further from the truth. Specialised plants including glassworts, sea-lavenders and Sea Purslane have evolved to cope with twice-daily inundation by sea water. Above the high tideline, intriguing salt-tolerant species thrive.
Portland Spurge is just one of the delights to greet visiting botanists on a spring trip to the extensive dune system of Braunton Burrows in Devon.
Sandy shores are beloved of holidaymakers but have much to offer the botanist too. On the landward side of the beach, colonising plants – notably Marram Grass – establish stable dune systems and subsequently these are colonised by maritime plants such as Sea Spurge as well as grassland species such as Viper’s-bugloss and Common Bird’s-foot-trefoil. Coastal shingle is a more challenging environment for a plant and it tends to be the domain of hardy specialists such as Sea-holly, Yellow Horned-poppy and Sea-kale.
In botanical terms, the stabilised shingle at Chesil Beach in Dorset is arguably the finest of its kind in Europe. Here, extensive carpets of Horseshoe Vetch can be seen, but Bird’s-foot-trefoil and Thrift also thrive in abundance.
CONSERVATION (#ulink_194bbfd8-0e63-5cc3-b909-7fd5ccbac5c6)
WORKING ON THIS PROJECT gave me the opportunity to visit many wonderful botanical locations across our region, the best of which are protected, to a degree, by nature reserve status and hence are still in good order. I also revisited many unprotected wayside botanical sites that I had not seen for several years. Sadly, most had become botanically impoverished and some had even lost the special plants for which they had been known. It will come as no surprise to learn that the majority of these sites were on areas of farmland.
WHAT’S GONE WRONG?
Threats to the countryside are all too obvious these days: the swallowing of land for housing, road schemes and the like, industrial and domestic pollution, and above all changes in agricultural practices – namely the unquestioning use of ever-more ‘efficient’ herbicides since the 1950s. And problems for wild flowers in the countryside do not stop with farming. Many landowners view the land they own as something to be exploited, if not for economic gain then as a playground, without a thought for conservation.
It has come to something when the discovery of Spreading Hedge-parsley, once a widespread arable ‘weed’, is a cause for botanical celebration. Without changes in agricultural practices, species such as this – already extinct at a local level in many areas – could disappear from Britain completely.
WHAT CAN BE DONE?
Legislation and agricultural grants relating to the way the countryside is managed need to target wildlife more intelligently than is currently the case, and development and change of land use should be subject to as much restriction as exists in the world of town planning. Easy to say, but much harder to put into practice. And there seems little cause for optimism, given that statutory bodies commanded with the responsibility for nature conservation are funded by government, itself perceived as being more receptive to economic than to environmental lobbies.
WHAT CAN YOU DO?
Object to, and oppose, all major development in the countryside and support organisations that are critical of the way intensive farming and insidious urbanisation have changed the botanical face of the landscape. On a small scale, grow as much of your own food as you can, garden organically, and use local organic sources for your additional needs whenever possible. Another way that the individual can help safeguard the British countryside is to donate as much money as possible to conservation organisations for the purchase of land to remove it from the threat of intensive farming or development. Suitable recipients of donations would include organisations such as Plantlife International, the various county Wildlife Trusts, the Woodland Trust, the National Trust and the RSPB.
Although walks in the countryside sometimes induce a sense of gloomy pessimism, budding botanists should not despair. Remarkably few flowering plant species have been lost entirely from Britain and Ireland in the last century and there are still plenty of wonderful botanically rich locations around the country. Nature reserves are thriving and, with your support and enthusiasm, things can only get better.
Thankfully, it is still possible to find agricultural fields where Cornflowers and other arable weeds thrive alongside the desired crop plant, either by design or where non-intensive farming methods are used. Let us hope that sights such as this become more commonplace as enlightenment, or financial inducements, change the way some of the land is farmed.
