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.
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.
More than 80 ecosystems in the Amazon Basin of Peru and Bolivia are classified and mapped in this report. The map is the first in Latin America to use the same criteria, scales and field validation to illustrate the natural vegetation across the two countries, and is expected to serve as a model to future vegetation maps in the region.
This report provides the first-ever analysis of the conservation status of Canadian plants and animals in a global context, finding that 6.4 percent — 360 species — are of global conservation concern. The assessment draws mostly on data from NatureServe and the network of Canadian conservation data centres.
This state-by-state analysis of U.S. biodiversity ranks all 50 states on several key biological characteristics, including diversity of species, endemism, levels of rarity and risk, and species already lost to extinction.
Nearly 600 terrestrial ecological systems in the United States, southern Alaska, and adjacent areas of Mexico and Canada are summarized in this report, which introduces and outlines the conceptual basis for a mid-scale classification unit: the ecological system.
A comprehensive assessment of aquatic biodiversity across the entire Upper Mississippi, including a complete classification of aquatic systems and identification of 22 areas of freshwater biodiversity significance.
This working ecological classification summarizes nearly 700 terrestrial ecological systems of Latin America and the Caribbean, and describes applications of these systems for conservation assessment, ecological inventory and monitoring, land management, and other uses.
A comprehensive analysis of the conservation status of the amphibians of North, Central, and South America and the Caribbean, where nearly two out of every five amphibians are threatened
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.
