This book represents the most comprehensive compilation of data on threatened vascular plants ever published. It includes the names of some 33,000 plant species determined to be rare or threatened on a global scale. Conservation assessments were provided by the IUCN Species Survival Commission, the National Botanical Institute (South Africa), Environment Australia, and CSIRO, The Nature Conservancy, the Smithsonian Institution, and the Royal Botanic Gardens, Kew, together with hundreds of botanic gardens and botanists throughout the world. The Royal Botanic Gardens Edinburgh and the New York Botanical Garden have made major in-kind contributions.The result of 20 years work by botanists and conservationists around the world, it is intended as a conservation tool, a provider of baseline information to measure conservation progress and as a primary source of data on plant species. Most importantly, however, it provides the building blocks on which to base a worldwide effort to conserve plant species.

This book aims to fulfil this long felt need giving details of ex-situ conservation of 20 arid species. Each chapter has information on taxonomic citation, physiognomic description, uses of these species, threats faced and its regeneration protocols. The presentation with large number of coloured photographs is in question answer style to increase the readability so as to get across the wide spectrum of conservation fraternity. This book will be useful to the students, teachers and researchers engaged in conservation biology, forestry, horticulture, plant ecology, agroforestry and desertification control programmes.

The Study of Plants in a Whole New Light “Matt Candeias succeeds in evoking the wonder of plants with wit and wisdom.” ―James T. Costa, PhD, executive director, Highlands Biological Station and author of Darwin's Backyard #1 New Release in Nature & Ecology, Plants, Botany, Horticulture, Trees, Biological Sciences, and Nature Writing & Essays In his debut book, internationally-recognized blogger and podcaster Matt Candeias celebrates the nature of plants and the extraordinary world of plant organisms. A botanist’s defense. Since his early days of plant restoration, this amateur plant scientist has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection. Using gardening, houseplants, and examples of plants around you, In Defense of Plants changes your relationship with the world from the comfort of your windowsill. The ruthless, horny, and wonderful nature of plants. Understand how plants evolve and live on Earth with a never-before-seen look into their daily drama. Inside, Candeias explores the incredible ways plants live, fight, have sex, and conquer new territory. Whether a blossoming botanist or a professional plant scientist, In Defense of Plants is for anyone who sees plants as more than just static backdrops to more charismatic life forms. In this easily accessible introduction to the incredible world of plants, you’ll find: • Fantastic botanical histories and plant symbolism • Passionate stories of flora diversity and scientific names of plant organisms • Personal tales of plantsman discovery through the study of plants If you enjoyed books like The Botany of Desire, What a Plant Knows, or The Soul of an Octopus, then you’ll love In Defense of Plants.

Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.

During the last hlO hundred years man has changed from living in equilibrium with the natural world which sustained him, to a new position in which he is now its undisputed ruler - and very often out of equilibrium - able in a matter of hours to reduce miles of forest to devastated, potential desert. This destructive and wasteful ability has increas~d dramatically over recent years. At the same time however the need for conservation, particularly of plants as a resource for the future, has also become apparent, along with the realisation that advanced technologies can produce more from existing agricultural and forest regions. This may to some extent relieve the heavy pressure on the vulnerable areas where short term over-exploitation leads to permanent destruction of whole ecosystems, and the attendant loss, for ever, of many of the animals and plants which originally lived there. There still remains today a vast number of plant species whose potential is unknown. Maybe they will never have more than aesthetic value to mankind. But who knows where, for example, the next anti cancer agent may be found. And anyway future generations may not be ready to accept such anthropocentric values, and the options should be kept open for the philosophical concept that all life on earth has a right to exist and that man has none to exterminate.

Discusses the various options for conserving plants at the level of the gene, species and community.

In the United States and Canada, thousands of species of native plants are edging toward the brink of extinction, and they are doing so quietly. They are slipping away inconspicuously from settings as diverse as backyards and protected lands. The factors that have contributed to their disappearance are varied and complex, but the consequences of their loss are immeasurable. With extensive histories of a cast of familiar and rare North American plants, The Quiet Extinction explores the reasons why many of our native plants are disappearing. Curious minds will find a desperate struggle for existence waged by these plants and discover the great environmental impacts that could come if the struggle continues. Kara Rogers relates the stories of some of North America’s most inspiring rare and threatened plants. She explores, as never before, their significance to the continent’s natural heritage, capturing the excitement of their discovery, the tragedy that has come to define their existence, and the remarkable efforts underway to save them. Accompanied by illustrations created by the author and packed with absorbing detail, The Quiet Extinction offers a compelling and refreshing perspective of rare and threatened plants and their relationship with the land and its people.
