This is a metamorphosing species spending most of its time on land in grassland habitat. It breeds in small pools and ponds, both artificial and natural.

Population

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

Population Trend

Decreasing

Major Threats

Introduced predatory fishes are the major threat to this species, but the habitat also has been heavily impacted due to extensive urban and agricultural expansion (leading to the desiccation and pollution of its breeding habitat).

Conservation Actions

It does not occur in any protected area, and the conservation and restoration of its habitats is urgent. It might be possible to breed this species in captivity. A survey is urgently needed to determine the current status of this species. Protected under the category Pr (Special protection) by the Government of Mexico.

Taxonomic Notes

The species boundaries between this species and both Ambystoma lermaense and A. rivularis require further investigation. However, these three taxa are clearly differentiated from all other Mexican ambystomatids (H.B. Shaffer pers. comm.).
