To understand almost any part of the tropical rain forest's fabulously complex web of life, one must first learn to identify a bewildering array of plants. Alwyn Gentry's landmark book, completed just before his tragic death in 1993, is the only field guide to the nearly 250 families of woody plants in the most species-rich region of South America.

As a consummate field researcher, Gentry designed this guide to be not just comprehensive, but also easy to use in rigorous field conditions. Unlike many field guides, which rely for their identifications on flowers and fruits that are only present during certain seasons, Gentry's book focuses on characters such as bark, leaves, and odor that are present year-round. His guide is filled with clear illustrations, step-by-step keys to identification, and a wealth of previously unpublished data.

All biologists, wildlife managers, conservationists, and government officials concerned with the tropical rain forests will need and use this field guide.

Alwyn Gentry was one of the world's foremost experts on the biology of tropical plants. He was senior curator at the Missouri Botanical Garden, and was a member of Conservation International's interdisciplinary Rapid Assessment Program (RAP) team, which inventories the biodiversity of the most threatened tropical areas. From 1967 to 1993 he collected more than 80,000 plant specimens, many of them new to science.

In this companion volume to the bestselling The Midwestern Native Garden: Native Alternatives to Nonnative Flowers and Plants, Charlotte Adelman and Bernard L. Schwartz offer another indispensible guide to replacing nonnative plants with native alternatives. This time, their subject is the native woody species that are the backbone of our gardens and landscapes. Among other ecological benefits, native shrubs and trees provide birds and butterflies with vital food and reproductive sites that nonnative species cannot offer. And they tend to be hardier and easier to maintain. The authors provide a comprehensive selection of native woody alternatives that, season by season, provide effects similar to those of nonnative shrubs and trees used for ornamental purposes and shade. These plants are suitable for all garden styles, provide blooms and fall color, and have the same cultivation requirements as their nonnative counterparts. Nature notes alert readers to the native species’ unique ecological roles. Unlike other gardening guides, Midwestern Native Shrubs and Trees goes beyond mere suggestion to provide gardeners with the tools they need to make informed, thoughtful choices. Knowing which native species to plant for desired effects empowers landscapers and gardeners to take on a greater role in protecting our midwestern environment.

A manual to identify trees and shrubs in winter when the lack of leaves, fruits, and flowers makes them least identifiable, Woody Plants in Winter has become a classic for naturalists, botanists, gardeners, and hobbyists. Earl L. Core and Nell P. Ammons, both West Virginia University Professors of distinction, originally published this book with The Boxwood Press in 1958. Now in its fifteenth printing, the title has come home to West Virginia University Press.

A comprehensive guide that includes a vast range of species and plant communities and employs thorough, original keys. Based primarily on vegetative characteristics, the keys don't require that flowers or other reproductive features be present, like many plant guides. And this guide's attention to woody plants as a whole allows one to identify a much greater variety of plants. That especially suits an arid region such as Utah with less diverse native trees. Woody plants are those that have stems that persist above ground even through seasons that don't favor growth, due to low precipitation or temperatures.

Woody Plants of Utah employs dichotomous identification keys that are comparable to a game of twenty questions. They work through a process of elimination by choosing sequential alternatives.

Detailed, illustrated plant descriptions complement the keys and provide additional botanical and environmental information in relation to a useful introductory categorization of Utah plant communities. Supplementary tools include photos, distribution maps, and an illustrated glossary.

Woody Plants of Western African Forests is an illustrated guide to the identification of 2200 trees, lianes and shrubs found in the forests of West Africa, from Senegal to Ghana. This is all the woody plants and more than 80% of the higher plants in the forests of this region, known to biogeographers as Upper Guinea. This represents 5% of all flowering plant genera in the world—1% of the species — so the book is relevant to anyone interested in tropical plants, especially but not only in the forests of tropical Africa.

Laid out as keys and with short descriptions of each species, it contains over 5,600 photographs, line drawings and maps. And, while many guides only offer hints to naming plants when they are not in flower, here the authors have based identification on leaves, bark, shoots, scent ,taste and other characters easily observed at most times.

Funded by the European Union, through its ECOSYN project (based at Wageningen University), which supports forest biodiversity and management in Upper Guinea, this magnificent, beautiful book is an indispensable reference for everyone committed to the conservation and sustainable development of Africa’s forest.
