The U.S. Fish and Wildlife Service has designated 764,200 acres of critical habitat for the jaguar (Panthera onca) under the Endangered Species Act (ESA). This habitat is found within Pima, Santa Cruz and Cochise counties in Arizona, and Hidalgo County in New Mexico.
The final rule reflects the following changes from the July 1, 2013, critical habit at proposal: exclusion of Tohono O’odham Nation lands (78,067 acres) as a result of the Tribe’s efforts working in partnership with the Service to conserve jaguar and other listed species’ habitat on the Nation’s sovereign land. Exemption of Fort Huachuca lands (15,867 acres) due to the conservation benefits to the jaguar provided in Fort Huachuca’s approved Integrated Natural Resource Management Plan.
The revised proposal was based on an updated habitat modeling report that more accurately reflected habitat essential to jaguars in northwestern Mexico and southwestern United States.
Mexico borderlands area is very different from habitat in Central and South America, where jaguars show a high affinity for lowland wet communities. Jaguars have been documented in arid areas of northwestern Mexico and southwestern United States, including thornscrub, desertscrub, lowland desert, mesquite grassland, Madrean oak woodland and pine oak woodland communities. Critical habitat in the United States contributes to the jaguar’s persistence and recovery across the species’ entire range by providing areas to support individuals that disperse into the United States from the nearest core population in Mexico.
Critical habitat is a term defined in the ESA and identifies geographic areas containing features essential to the conservation of a threatened or endangered species and that may require special management considerations or protection. The designation of critical habitat does not affect land ownership or establish a refuge, and has no impact on private landowners taking actions on their land that do not require federal funding or permits.
