The Center for Biological Diversity and Defenders of Wildlife, represented by Earthjustice in the suit, argue that Fish and Wildlife Service’s new rule fails to respond to ongoing genetic threats to Mexican gray wolves, sets an inadequate population target, and cuts wolves off from essential recovery habitat.

New management rule sets target of 320 wolves in a single area of eastern Arizona and western New Mexico

Decision forces U.S. Fish and Wildlife Service to fix flawed recovery plan

Our legal win forces the US Fish and Wildlife Service to develop a real plan to stop human killing of Mexican gray wolves.

Decision forces U.S. Fish and Wildlife Service to fix flawed Mexican Gray Wolf Recovery Plan.

Meet the Mexican gray wolf, one of the most endangered mammals in North America. Experts believe the genetically weak population could rebound if more wolves are released into the wild. So why is this wolf, and so many of her kind, living out a life in captivity?

In lead case No. CV-15-00019-TUC-JGZ, Plaintiff CBD’s Motion for Summary Judgment (doc. 114) is GRANTED IN PART and DENIED IN PART to the extent provided herein. Federal Defendants’ Cross-Motion for Summary Judgment (doc. 123) is DENIED.

Ruling rejects measures that hurt, instead of help, rare wolves

El plan ignora la ciencia, falla en acciones de recuperación urgentes

A coalition of wolf advocates today filed a lawsuit challenging the Trump administration’s deeply flawed recovery plan for the Mexican gray wolf, one of North America’s most endangered mammals

Plan ignores science, fails on urgently needed recovery actions

Plan ignores the science and falls short in several key ways

A plan by the U.S. Fish and Wildlife Service aims low, involving too small a habitat and too few wolves.

Lobos are the most genetically distinct lineage of wolves in the Western Hemisphere. They are also one of the most endangered mammals in North America. We still have a chance to save them.

En su ensayo “Pensando como montaña”, el legendario conservacionista Aldo Leopold describe una época en su juventud donde era impensable “dejar pasar la oportunidad de matar a un lobo”. Sin embargo, cuando se enfrentó al “implacable fuego verde” de los ojos de uno de estos animales a punto de morir, dicha filosofía se llenó de dudas.
