England's Rare Mosses and Liverworts
Their History, Ecology, and Conservation
Ron D. Porley
This is the first book to cover England's rare and threatened mosses and liverworts, collectively known as bryophytes. As a group, they are the most ancient land plants and occupy a unique position in the colonization of the Earth by plant life. However, 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 its mosses and liverworts are not well known outside a small band of experts. This has meant that conservation action has tended to lag behind that of more charismatic groups such as birds and mammals. Of the 916 different types of bryophyte in England, 87 are on the British Red List and are regarded as threatened under the strict criteria of the International Union for the Conservation of Nature.
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 useful, 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.
