Critical Supplement To The Atlas Of The British Flora

Over the past 50 years, major changes have taken place in the distribution of aquatic plants in Europe. Many species have declined whilst other species have increased in abundance or spread, including several that were originally introduced from the New World. Despite the relative richness of the aquatic flora of Britain and Ireland, it is a neglected area of study. This book is not an identification manual but provides a summary of the distribution, habitat and reproductive biology of 200 taxa in 72 genera, with individual distribution maps, and also summarizes their distribution overseas. A joint project of I.T.E. (now C.E.H.), the Joint Nature Conservation Committee and the Environment Agency.

Originally published in paperback in 1990, this book's purpose was the accurate identification of all British plants.

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

This totally new and much needed work on the County’s flora – published in association with the Hampshire and Isle of Wight Wildlife Trust – is the first comprehensive study for nearly a century. Excluding the Isle of Wight, it contains over 1750 species of vascular plants including some non-indigenous speces as well as subspecies, varieties and hybrids. In addition, condensed accounts of the lichens (590 taxa) and bryophytes (459 taxa) – groups in which the county is particularly rich – have been contributed by Francis Rose with Ken Sandell and Alan Crundwell respectively. As in Townsend’s Flora of Hampshire (1884), there are introductory chapters on Structure and Geology; Climate; Habitats; and an up-to-date Comparison of Hampshire’s Flora with some other southern Counties (including the Isle of Wight) – all by Francis Rose. There are also chapters on Conservation of the Flora (with a complete list of nature reserves) by Peter Brough and Paul Bowman; Some earlier Workers on the Hampshire Flora by David Allen; and Botanical Recording by Paul Bowman. The Flora ends with an extensive Bibliography and References and a fully comprehensive Index. The principal authors are all experienced Hampshire botanists with an intimate knowledge of its flora.

This critical Flora provides a definitive account of the native species, naturalised species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions will enable the user to name all plants occurring in the wild, plus some ornamental trees and shrubs. For the first time detailed accounts of all the large apomictic genera are given and many infraspecific variants included. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, including information on flowering period, pollination and chromosome number. Separate descriptions are given for infraspecific taxa. Information on the status, ecology and distribution (including worldwide distribution) of the species and infraspecific taxa is also given. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features in a number of groups of plants.
