Forest Trees of Australia is the essential reference for observing, identifying and obtaining information on the native trees in this country. It describes and illustrates over 300 of the most important indigenous trees, which have been carefully selected for their environmental significance, their importance to the timber industry, or their prominence in the landscape. This new and thoroughly revised edition has been fully updated throughout and includes treatments of 72 additional species. New maps and photographs show a wonderfully diverse range of forests, from mangrove swamps, tropical regions and deserts, to alpine areas and majestic stands of temperate forests. A color section illustrates some of the major forest types of Australia and bark from a diverse range of species. Forest Trees of Australia is an unsurpassed guide to identification for horticulturists, botanists, foresters, students, farmers, environmentalists and all those who are interested in Australian native trees.

Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.

The CABI Encyclopedia of Forest Trees provides an extensive overview of 300 of the world's most important forest trees. Tropical, subtropical, temperate and boreal trees of major economic importance are included, covering tree species used in agroforestry practices around the world. Many of the species covered are considered to be multipurpose trees with uses extending beyond timber alone; the land uses such as watershed protection or provision of windbreaks, and non-wood uses such as the production of medicines, resins, food and forage, are also listed. Comprehensive information is presented on each tree's importance, with a summary of the main characteristics of the species, its potential for agroforestry use and any disadvantages it possesses. The tree's botanical features such as habit, stem form, foliage, inflorescence, flower and fruit characters and phenology are covered in detail with over 70 color plate pictures to aid identification. Also included are specific sections devoted to pests and diseases, distribution and silvicultural characteristics and practices, including seed sowing, nursery care, planting, thinning, and harvesting. In addition to the wealth of information detailed, based on datasheets from CABI's Forestry Compendium, selected references for further reading are provided for each entry, making this book an essential reference work for forestry students, researchers and practitioners.

Trees of San Francisco introduces readers to the rich variety of trees that thrive in San Francisco's unique conditions. San Francisco's cool Mediterranean climate has made it home to interesting and unusual trees from all over the world - trees as colorful and exotic as the city itself. This new guide combines engaging descriptions of sixty-five different trees with color photos that reflect the visual appeal of San Francisco. Each page covers a different tree, with several paragraphs of interesting text accompanied by one or two photos. Each entry for a tree also lists locations where "landmark" specimens of the tree can be found. Interspersed throughout the book are sidebar stories of general interest related to San Francisco's trees. Trees of San Francisco also includes a dozen tree tours that will link landmark trees and local attractions in interesting San Francisco neighborhoods such as the Castro, Pacific Heights and the Mission - walks that will appeal to tourists as well as Bay Area natives.

This data-rich book demonstrates the value of existing national long-term ecological research in Australia for monitoring environmental change and biodiversity. Long-term ecological data are critical for informing trends in biodiversity and environmental change. The Terrestrial Ecosystem Research Network (TERN) is a major initiative of the Australian Government and one of its key areas of investment is to provide funding for a network of long-term ecological research plots around Australia (LTERN). LTERN researchers and other authors in this book have maintained monitoring sites, often for one or more decades, in an array of different ecosystems across the Australian continent – ranging from tropical rainforests, wet eucalypt forests and alpine regions through to rangelands and deserts. This book highlights some of the temporal changes in the environment that have occurred in the various systems in which dedicated field-based ecologists have worked. Many important trends and changes are documented and they often provide new insights that were previously poorly understood or unknown. These data are precisely the kinds of data so desperately needed to better quantify the temporal trajectories in the environment in Australia. By presenting trend patterns (and often also the associated data) the authors aim to catalyse governments and other organisations to better recognise the importance of long-term data collection and monitoring as a fundamental part of ecologically-effective and cost-effective management of the environment and biodiversity.
