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.

In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversity--home to a dizzying number of plants and animals, many endemic, it's a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica's ecosystems. It systematically covers the entire range of Costa Rica's natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca's), and its estuaries, rivers, lakes, swamps and bogs.

At the heart of evolution lies a bewildering paradox. Natural selection favors above all the individual that leaves the most offspring—a superorganism of sorts that Jonathan Silvertown here calls the "Darwinian demon." But if such a demon existed, this highly successful organism would populate the entire world with its own kind, beating out other species and eventually extinguishing biodiversity as we know it. Why then, if evolution favors this demon, is the world filled with so many different life forms? What keeps this Darwinian demon in check? If humankind is now the greatest threat to biodiversity on the planet, have we become the Darwinian demon? Demons in Eden considers these questions using the latest scientific discoveries from the plant world. Readers join Silvertown as he explores the astonishing diversity of plant life in regions as spectacular as the verdant climes of Japan, the lush grounds of the Royal Botanical Gardens at Kew, the shallow wetlands and teeming freshwaters of Florida, the tropical rainforests of southeast Mexico, and the Canary Islands archipelago, whose evolutionary novelties—and exotic plant life—have earned it the sobriquet "the Galapagos of botany." Along the way, Silvertown looks closely at the evolution of plant diversity in these locales and explains why such variety persists in light of ecological patterns and evolutionary processes. In novel and useful ways, he also investigates the current state of plant diversity on the planet to show the ever-challenging threats posed by invasive species and humans. Bringing the secret life of plants into more colorful and vivid focus than ever before, Demons in Eden is an empathic and impassioned exploration of modern plant ecology that unlocks evolutionary mysteries of the natural world.
