Atlas of Global ConservationThe Nature Conservancy has produced a lovely hardcover Atlas of Global Conservation. An interactive version is available at http://www.nature.org/atlas/.
With The Atlas of Global Conservation, readers can take measure of their own place in the world, not only by longitude and latitude but also by the types of habitats surrounding them, by the species that flourish at home but not elsewhere, and by the amount of conservation that has been done — or could be.
The atlas breaks critical new ground in global mapping, for the first time delineating specific freshwater and marine systems such as salt marshes and kelp forests. It also includes first-ever maps of where high concentrations of freshwater birds, seabirds and marine mammals occur.
The edition includes 100 full-color maps and charts, prepared from databases from 70 institutions, including a equation on how quickly humans move in natural areas donated by the Swedish army.

Mapping the Biosphere
Shaan W recently pointed us to another source of environmental maps called Mapping the Biosphere, a project of the Center for Sustainability and the Global Environment (SAGE), part of the Nelson Institute for Environmental Studies at the University of Wisconsin - Madison. Datasets are downloadable in ESRI ArcView format.
