Four Species on the Brink

This report summarizes the most relevant and up-to-date information on four charismatic species affected by the fragmentation of habitat and disruption of movement corridors resulting from the existing and proposed border infrastructure and associated militarization. It focuses on the Arizona-Sonora border and covers a small portion of western New Mexico’s border with Chihuahua, but its framework and broad themes are relevant to any evaluation of impacts to wildlife across the entire U.S.-Mexico border.

Jaguar Draft Recovery Plan

The jaguar is listed as endangered throughout its range under the Endangered Species Act of 1973 (ESA), as amended (16 U.S.C. 1531 et seq.). Historically, the jaguar inhabited 21 countries throughout the Americas, from the U.S. south into Argentina. Currently, jaguars are found in 19 countries: Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, United States (U.S.), and Venezuela. The species is believed to be extirpated from El Salvador and Uruguay. The goal of this revised recovery plan is to recover and delist the jaguar, with downlisting from endangered to threatened status as an intermediate goal.
