The Río Balsas Depression is located in several States that drain to the Pacific Ocean, in Puebla State, Mexico. It is located in the southern part, in the region called Mixteca Region, which is an ethical zone with ecosystems with low agricultural and forest potential, in its rough summer pasture there are areas with different types of natural vegetation; where the white-tailed deer is distribute “in situ” from the “mexicanus” subspecies. The objective of the present work was to determine the diversity and botanical composition of the diet of the cervid in the region, by means of application of diverse field’s and laboratory’s techniques; due to one of the bases for the managing of the species is to know its feeding. For it, there were realized direct and indirect observations of deer’s grazing in 49 transects of 500 m length by 6m width, in seven Units for the Management and Wildlife Conservation or UMAs, from five Municipalities, where the browsed and excreted plants were collected for microhistology. By direct and indirect observation method of browsed plants, there were registered 139 species belonging to 51 families; leguminous represent 20.1% (N =28), followed by cactaceae 13.7% (N =19), gramineous with 7.2% (N =10), agavaceae with 6.5% (N =9) and asteraceae with 5.8% (N =8). In addition; they were detected by microhistology in feces to 60.1% (N =8%). In agreement to the contribution in MS's composition, 17 species stand out. These results repeat the important contribution of leguminous to the diet, and the great diversity of plants used as forage for this cervid.
