Nelson's woodrat

Nelson's woodrat (Neotoma nelsoni) is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is known only from the eastern slopes of the volcanoes Orizaba and Cofre de Perote.^[1] Due to the small geographic range, isolation, and low population, the Nelson's woodrat has a higher risk for extinction.^[2] The distribution and population sizes are small. The population exists in geographic isolation, which prevents gene flow^[2]

Threats

Currently the Nelson's woodrat is threatened by agriculture and invasive species. In Mexico, a conversion to agriculture is taking place which is taking away the home of the Nelson's woodrat. Exotic and invasive species pose a threat to the Nelson's woodrat as potential predators.^[4]
