Soils of Tropical Forest Ecosystems: Characteristics, Ecology and Management

by R. Toby Pennington (Editor), James A. Ratter (Editor)

More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these neotropical biomes receive nowhere near the attention they should - in terms of both research and conservation -considering the amount of land they encompass and the diversity of vegetation they contain. Neotropical Savannas and Dry Forests: Plant Diversity, Biogeography, and Conservation provides an engaging synthesis of information on the plant diversity and geography, as well as the conservation status, of these species-rich areas. This impressive compilation is the result of a plant diversity symposium that took place during an international conference on tropical savannas and seasonally dry forests held in 2003. Fifty leading scientists, representing a variety of disciplines have contributed to the chapters of this book in an effort to address three questions:

• What are the patterns of diversity, species-richness and endemism of the floras of neotropical seasonally dry forest and savannas?
• How and why did this endemism and diversity arise?
• Are these ecosystems adequately protected and, if not, which areas should be elevated into priorities for conservation, and how can this be best achieved? This work is the first extensive compilation of the patterns of plant biodiversity in these neotropical ecosystems. The overview also provides a summary of what is known of their evolutionary history, including an examination of the links to the development of analogous vegetation in Africa. In contrast to previously published titles that emphasize ecology and physiology, this work focuses on plant biodiversity and reviews molecular phylogenetic and molecular population genetic approache

Can we prevent the destruction of the world's tropical forests? In the fire-scarred hills of Costa Rica, award-winning science writer William Allen found a remarkable answer: we can not only prevent their destruction--we can bring them back to their former glory. In Green Phoenix, Allen tells the gripping story of a large group of Costa Rican and American scientists and volunteers who set out to save the tropical forests in the northwestern section of the country. It was an area badly damaged by the fires of ranchers and small farmers; in many places a few strands of forest strung across a charred landscape. Despite the widely held belief that tropical forests, once lost, are lost forever, the team led by the dynamic Daniel Janzen from the University of Pennsylvania moved relentlessly ahead, taking a broad array of political, ecological, and social steps necessary for restoration. They began with 39 square miles and, by 2000, they had stitched together and revived some 463 square miles of land and another 290 of marine area. Today this region is known as the Guanacaste Conservation Area, a fabulously rich landscape of dry forest, cloud forest, and rain forest that gives life to some 235,000 species of plants and animals. It may be the greatest environmental success of our time, a prime example of how extensive devastation can be halted and reversed. This is an inspiring story, and in recounting it, Allen writes with vivid power. He creates lasting images of pristine beaches and dense forest and captures the heroics and skill of the scientific teams, especially the larger-than-life personality of the maverick ecologist Daniel Janzen. It is a book everyone concerned about the environment will want to own.
