Multi-scale modeling of four-toed salamander habitat preference


April 2006 - December 2012


The four-toed salamander, a small cryptic animal, is infrequently observed in the Northeast, and thus believed to be a rare species in the region. To evaluate whether the species is truly rare, or just difficult to observe, we will use the results from field surveys to build local and landscape models of preferred habitat, and then validate these models by ground-truthing. Results will be used by the Massachusetts Division of Fisheries and Wildlife to direct conservation efforts and determine the status of the species.
