How are the nation’s plants and animals faring? Which species are at greatest risk and most in need of special care to ensure their survival? Conservation of our natural resources often requires difficult choices, and in an era of limited resources we must have clear priorities that provide answers to questions such as these. The 1997 Species Report Card: The State of U.S. Plants and Animals addresses this need by providing the latest figures on the condition of our species from the scientific databases of the Natural Heritage Network and The Nature Conservancy.
