A 2001 Supreme Court decision potentially eliminated wetlands and other waters that are “isolated” from navigable waters from jurisdiction of the Clean Water Act. This report assesses the potential impacts of the decision on biodiversity.
The report presents the most detailed study of its kind ever carried out, in which scientists identified 12 previously unknown centers of endemism — areas that safeguard species found nowhere else in the world — in the Eastern Andean slope and Amazon basin of Peru and Bolivia. The report also illustrates distribution maps for 782 endemic species of plants, mammals, amphibians, and birds in unprecedented detail.
The most complete analysis ever of the conservation status of this nation's plants, animals, and ecosystems, Precious Heritage reveals that one-third of our species are at risk.
Kentucky’s Natural Heritage: An Illustrated Guide to Biodiversity provides an essential reference to the state's natural history and unique biological patchwork—a rallying cry for the conservation of this priceless legacy.
Synthesizing the experiences of more than two dozen sites around the world, this booklet describes how marine managed areas (MMAs) increase the diversity and abundance of native organisms and ecosystem resilience for generations to come.
