An authoritative two-volume overview of the distribution of the wild plants of Great Britain and Ireland Plant Atlas 2020 presents the results of field surveys by the Botanical Society of Britain and Ireland, building on past atlas surveys undertaken by the Botanical Society in the early and late twentieth century. Drawing on the work of thousands of botanists who covered the entirety of Britain and Ireland between 2000 and 2019, this two-volume book features introductory chapters that provide a detailed assessment of the changes to the region’s flora over the past hundred years. Distribution maps and accompanying text and graphics display the phenology, altitudinal range, and time-series trends for 2,616 native and alien species and 247 hybrids. With more than 30 million records gathered during the project, Plant Atlas 2020 will serve as an essential resource for the study and conservation of these wild plants and their vitally important habitats for decades to come. The most in-depth survey of British and Irish flora ever undertaken, based on more than 30 million individual records Covers 2,616 native and alien species and 247 hybrids Features a wealth of distribution maps and infographics, accompanied by informative text A must-have reference book for botanists, field naturalists, conservation organizations, government agencies, and anyone interested in the diverse plant life of Great Britain and Ireland

Since its first publication in 1991, New Flora of the British Isles has become established as the standard work on the identification of the wild vascular plants of the British Isles. The Flora remains unique in many features, including its full coverage of all British wild plants, its user-friendly organisation, and its specially compiled keys and descriptions. This new edition includes the addition of more than 160 species, so that 4,800 taxa are now covered in varying degrees of detail. It also incorporates the new molecular system of classification based on DNA sequences. Furthermore, it includes 1600 species illustrations, rewritten distributions and an overhaul of the designation of degrees of rarity, with the introduction of a third, less rare, category. These revisions should ensure that this third edition remains the essential reference source for all taxonomists, ecologists, conservationists, plant hunters and biogeographers, whether they be researchers, teachers, students or amateurs.

The orchid family is one of the largest plant families in the world, reaching its highest diversity in the tropics where their exotic and colourful flowers are often truly breathtaking. Britain and Ireland have just 52 species of wild orchid, some of which are rare or scarce, whilst others are surprisingly inconspicuous. Yet, whether large or small, all orchids share flamboyant flower structures and incredible beauty. This pocket guide allows the identification of all species of orchid in the British Isles. It has concise text highlighting ID criteria as well as notes on biology, habitat and conservation, along with stunning colour photographs and accurate range maps based on maps compiled by the Biological Record Centre. This book provides the perfect guide to these beautiful and evocative plants, and is a must for any field naturalist.
