Coahuilan Box Turtle Conservation
The Coahuilan Box Turtle (Terrapene coahuila) is listed as Endangered by the IUCN (International Union for the Conservation of Nature), the U.S. Endangered Species Act, and the Mexican Government. It is found only in the intermontane Cuatrociénegas Valley of north-central Mexico. T. coahuila is the only aquatic member of its genus. It is found primarily in small spring-fed wetlands (cienegas) and pools (pozas) set in Chihuahuan Desert habitat.
The species has experienced a serious population decrease over the past half century, declining from an estimated size of 10,000 in 1974 to 2,500 in the early 2000s to possibly no more than 1500 in 2019. The primary threats are habitat loss and degradation due to a lowering of the water table from encroaching agriculture both in the Cuatrociénegas Valley and in areas with contributing aquifers outside the basin. Efforts are underway to save critical habitat, but the development of a strong, in-country captive colony for the species is a vital component to assuring a future for the species.
Your donation will go directly to support the development and maintenance of an in-country captive breeding program led by Dr. Gama Castañeda (University of Juarez in the State of Durango).
