It is also harvested for food in parts of its range, in particular in the south, a threat that is thought to be increasing. In addition, there is widespread habitat destruction and degradation through much of its range, primarily as a result of logging of its pine-oak forest habitat.

Conservation Actions [top]

Conservation Actions: The range of this species does not include any protected areas, and improved protection and maintenance of forest habitat in the species' range is required. It is also necessary to ensure that offtake of this species from the wild for human consumption is managed sustainably. This species is protected by Mexican law under the "Special Protection" category (Pr).
