 The Tehuantepec jackrabbit is jeopardized by habitat loss and fragmentation, poaching, small population size, and genetic isolation.Introduction of exotic grasses, frequent and induced fires, agricultural and cattle-raising activities, and human settlements are deteriorating the floristic diversity and native vegetation structure in savannas inhabited by Tehuantepec jackrabbits.Locally, the Tehuantepec jackrabbit is taken occasionally as subsistence hunting, and very occasionally as pets in rural communities.
