Book excerpt: The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.

Download or read book CYCADS OF WORLD 1E written by JONES DAVID L and published by Smithsonian. This book was released on 1993-06-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cycads superficially resemble palms and are often misidentified as such. However, cycads are actually a unique assemblage of primitive plants that have been around for at least 250 million years. Because of their great antiquity they have been described as living fossils and the coelacanths of the plant world." "Cycads were an important source of food for the dinosaurs and, despite their toxicity, they have been prepared for food and valued by many cultures. Today they may be regarded as relicts, still widely distributed but diminished in diversity and persisting only in small disjunct communities. They have become highly sought after for gardens, both private and public, and their present status as endangered plants has engendered an upsurge of interest in their conservation." "With Cycads of the World David Jones has achieved that difficult task of writing a scientifically accurate text which is easy both to read and to understand. The book covers all 185 living species in their 11 genera. It has over 250 color photographs, many descriptive line drawings, identification keys, distribution maps, and 16 fine old color engravings previously hidden away in antique volumes. David records the prehistory and history of cycads and their economic importance. He provides detailed information on their cultivation, biology, and propagation. The book will appeal to gardeners, landscape architects, horticulturists, botanists, conservationists, and curious general readers alike."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Cycads Weevils and Africa written by Doug Downie and published by . This book was released on 2021-05-20 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cycads are an ancient and engrossing group of plants, which are in process of being loved to death by wealthy collectors for the horticultural market the world over. One purpose in writing the book was to foster awareness of the plants and concern about their predicament. A larger purpose is to open a door into the wonderful workings of tiny insects and their interactions with and importance to their host plants. The book is about more than just the scientific setting. It is also, and maybe mostly, about the places and people encountered along the way. It is part science, part natural history, part travelogue, part memoir. It may not appeal to a mass audience, but it is a fact that there are some who will be interested. These are the cycad enthusiasts, who are passionate in their pursuit of the latest works on cycads. It is likely that other people who are curious about organisms other than themselves, and places on the planet other than their own, and about science, and who can relate to the self-doubting quest for knowledge, will find the book interesting.
