Precious heritage

Sinopse

A vast land of contrasts, the United States stretches from above the Arctic Circle to below the tropic of Cancer, and spans nearly a third of the globe, from eastern Maine to the tip of the Aleutian chain. Within this area exists an immense variety of ecosystems, supporting a wealth of plant and animal life. Precious Heritage provides a comprehensive and beautifully illustrated overview of that biological diversity. Sponsored by The Nature Conservancy and the Association for Biodiversity Information, this book draws together for the first time more than 25 years of information from U.S. natural heritage programs, a national network of state biodiversity inventories.
