Mammals of the Tonto National Forest

The Tonto National Forest encompasses approximately 2.8 million acres ranging in elevation from 1300 feet near the Salt River to over 7,700 feet at Aztec Peak. The forest contains a variety of habitats that include coniferous forests and woodlands, chaparral, grassland, desert scrub and riparian. This diversity supports complex assemblages of wildlife and plants. This checklist is designed to help the Forest visitor enjoy and appreciate one segment of this diverse resource. The checklist contains information on 92 species of mammals known to occur on the Forest.

Using the Checklist

The columns following the name of each species are intended to help with identification. Abundance refers to how numerous a species is in relation to other species.


C – common

F – fairly common

U – uncommon

R – rare

E – extirpated


The remaining columns describe the vegetation type where each species is most likely to be encountered. The map of general vegetation types on the Forest is designed to serve as a reference for approximate location of major vegetation types. Some mammals require specific habitat features (meadows, caves, rocks, etc.) within a broad vegetation type and are indicated by the “Niche” column. Other mammals are widespread or non-specific to a vegetation type and occurrence is indicated under “Variety of Types”, but some of these may also inhabit only specific features within the types.


The capital letter in parenthesis following the name indicates the species’ status as Endangered, Threatened, Proposed, or Candidate by the Fish and Wildlife Service or Sensitive in the Southwestern Region of the Forest Service.
