This is the first book to cover England's rare and threatened mosses and liverworts. Many are at risk from habitat loss, pollution, climate change, and other factors. Britain is one of the world's best bryologically recorded areas, yet of the 916 different types of bryophyte in England, 87 are on the British Red List and are regarded as threatened by the IUCN. This book aims to raise awareness by providing stunning photographs, many never before published, of each threatened species, as well as up-to-date profiles of 84 of them, including status, distribution, history, and conservation measures. The book looks at what bryophytes are, why they are important and what makes them rare; it also examines threats, extinctions, ex situ conservation techniques, legislation, and the impact of the 1992 Convention on Biological Diversity.
