Book Description
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.

Book Description
This volume presents the current state of our knowledge of the classification of the approximately 300 species of cycads. It includes contributions from leading researchers from Australia, China, Italy, Mexico, South Africa, Thailand and the USA. It has been developed from papers presented at a workshop held in 2002 at the Montgomery Botanical Center. The book provides guidelines for the designation of species, species boundaries and species groupings, thus clarifying what has been a confused area of research.

Book Description
Use of and trade in wildlife is a fact of life for human society around the globe. Article IV of the CITES Convention requires that exporting countries restrict trade in Appendix II species to levels that are not detrimental either to species? survival, or to their role within the ecosystems in which they occur (known as the ?non-detriment finding?). Based on two workshops convened by IUCN to develop some pragmatic assistance for Scientific Authorities, this publication presents the background to the development of the non-detriment finding checklist and explains how the checklist itself is designed to work, in the hope that Scientific Authority staff will take and develop the parts of the approach that they find useful.

Book Description
This User's Guide covers the widely traded cactus family and how it is regulated by the Convention on International Trade in Endangered Species (CITES). The text is written for the non-expert and the guide explores the major groups of cacti in trade, their distribution, conservation status, use and levels of trade as well as the likelihood of illegal trade. All CITES Appendix I taxa are covered in detail and a wide selection of the Appendix II taxa. Major exemptions from CITES regulations are also outlined, including cacti not covered by CITES. The guide includes a fully illustrated PowerPoint training presentation with comprehensive speaker notes on CD-ROM.

Book Description
This book highlights the rapidly expanding horizons of Plant Sciences. The conventional aspects of Botany remain the backbone of this subject, but the growing population and environmental compulsions urge man to explore new avenues to tackle the problems of society. Most of these areas, which are interdisciplinary in nature and provide new and better solutions, are pursued vigourously by researchers in Plant Sciences. Medicinal plants including Nutraceuticals, Biofuels, Natural Dyes, Biofertilisers, Biopesticides, Plant propagation methods including Tissue culture, Plant Genomics, Proteomics, Climate change and Remote sensing techniques inclusive of GIS are some of the such emerging areas focused in this book. The present book contains a good number of scien-tific articles penned by expert researchers in all these fields. Since researches in these areas are pursued in many of the Research centres and Universities, this book will be a valuable and essential reference book for one and all who are interested in these subjects.

Book Description
Stout cycads are an ancient plant species, pre-dating dinosaurs and remaining virtually unchanged for millions of years. These "living fossils" offer an important link to prehistoric times, and their rarity and highly threatened status mean regulations are more important than ever. CITES and Cycads offers straightforward guidance on the trade regulations set by the Convention on International Trade in Endangered Species (CITES), combining rules and exemptions with information on distribution, trade routes, and conservation status. Written for the non-expert, it features identification tips and a checklist of cycad species as well as notes on illegal trade and suggestions on handling enforcement. A CD-ROM containing a fully illustrated PowerPoint with speaker's notes rounds out this comprehensive guide to regulating these venerable and tenacious plants.
