Book Description
There are few plants that can rival cycads for variety of foliage, size, and form. Loran Whitelock has spent decades studying these diverse plants in their natural habitats around the world and in cultivation, allowing him to provide firsthand, reliable information with special emphasis on their cultivation in a variety of climates and their propagation.

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
The Flowering of Australia’s Rainforests provides a comprehensive introduction to the pollination ecology, evolution and conservation of Australian rainforest plants, with particular emphasis on subtropical rainforests and their associated pollinators. This significantly expanded second edition includes new information on the impact of climate change, fire, fragmentation and invasive species. Rainforests continue to be a focus of global conservation concern, not only from threats to biodiversity in general, but to pollinators specifically. Within Australia, this has been emphasised by recent cataclysmic fire impacts, ongoing extreme drought events, and the wider consideration of climate change. This second edition strengthens coverage of these issues beyond that of the first edition. The Flowering of Australia’s Rainforests makes timely contributions to our understanding of the nature and function of the world’s pollinator fauna, plant-reproduction dependencies, and the evolutionary pathway that has brought them to their current state and function. Illustrated with 150 colour plates of major species and rainforest formations, this reference work will be of value to ecologists and field naturalists, botanists, conservation biologists, ecosystem managers and community groups involved in habitat restoration.
