This species occurs from southern Nayarit and western Jalisco, east to northern Michoacán, and southern Guanajuato, Mexico. It occurs from 823-1,520m asl.
Habitat and Ecology
This species is predominantly an aquatic species that inhabits and breeds in permanent lakes, rivers and pools in shrubland and pine-oak forest.
It was previously a common species, but there has been a recent decline particularly in the southern part of its distribution.
Water pollution is a major threat to this predominantly aquatic species. 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.
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).
Red List Status
Listed as Vulnerable because of an observed population decline, estimated to be more than 30% over the last three generations, due to over-exploitation, water pollution, and habitat destruction and degradation.
