This impressive source for information about endangered mammals is the result of more than a decade of research by Dr. Paul Massicot, who spent 30 years working at the Maryland Department of Natural Resources. Site visitors can locate specific endangered species by browsing the Individual Species Index (either by common or scientific name). The species pages contain references, images, and concise information about population estimates, birth season, density and range, habitat, diet, and more. Visitors can conduct keyword searches, or browse the Species Group Index as well. The site also includes an Index of Countries which provides a list of threatened mammal species in each country as well as some basic statistics regarding Environmental and Social Data such as land use, ecosystems, economy, education, and human population. In addition, the website contains information about the World's Rarest Mammals, and a solid collection of related links.
