Abstract. This paper examines the frequency of presence of bobcats and coyotes in six vegetation units in the southern region of the Valley of Mexico, as indicated by scent stations. The bobcat was recorded with more frequency than anticipated in pine forests, fir forests and bush/grasslands. The coyote was present most frequently in pine forest, fir forest and mixed forest. The results have been formulated into spatial distribution models for the bobcat and the coyote, that can aid in formulating conservation and management actions for the study area.
