From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality, San Martin, in north-western State of Mexico, at 2,500m asl.

Habitat and Ecology

This is a metamorphosing species spending most of its time on land in a mosaic of natural grasslands and pine-oak forests, living in somewhat more open habitats than Ambystoma amblycephalum. It requires ponds and small streams in which to breed.


There is no information on the population status of this species.

Population Trend


Major Threats

The habitat of this species is under threat from agriculture, in particular from commercial wheat farming, leading to the desiccation and pollution of its breeding lakes and water reservoirs within its small range. However, survival of this species appears to be compatible with cattle grazing, particularly if stock ponds are available for breeding. Introduced predatory fish also pose a serious threat to this species.

Conservation Actions

It does not occur in any protected areas, making the conservation and restoration of the natural habitats for this species urgent. It might be possible to breed this species in captivity, in which case captive animals could be a source of new individuals to repopulate natural habitats. It is protected under the category Pr (Special protection) by the Government of Mexico.
