Court Rules Federal Officials Must Address Poaching of Mexican Wolves in New Recovery Plan

Decision Forces U.S. Fish and Wildlife Service to Fix Flawed Recovery Plan

TUSCON, Ariz.— In response to a lawsuit by conservation groups, a judge has ruled that the U.S. Fish and Wildlife Service must add specific actions to address illegal killing of Mexican wolves to its plan for the species’ recovery.

The groups’ 2018 lawsuit claimed that the plan failed to meet basic requirements of the Endangered Species Act to provide site-specific management actions and objectives with measurable recovery criteria to address the most immediate threat facing the Mexican wolf recovery program since its inception: illegal killing.

Earthjustice represented the Center for Biological Diversity, Defenders of Wildlife, Endangered Wolf Center, Wolf Conservation Center and David Parsons, former Mexican wolf recovery coordinator for the Service.

“More than 70% of documented Mexican wolf mortalities are human-caused,” said Elizabeth Forsyth, Earthjustice attorney. “We’re glad that the court has recognized that for the Mexican wolf to survive, the Fish and Wildlife Service must put in place a robust plan that includes concrete actions to address the threat of illegal killing.”

“The path to recovery for the Mexican wolf has been hampered by widespread poaching for far too long,” said Michael Robinson at the Center for Biological Diversity. “Now that the Fish and Wildlife Service has to take this issue seriously, we hope these wolves will stand a better chance of survival.”

“Ensuring that wolves and people can coexist is an essential part of long-term success for Mexican gray wolf recovery,” said Bryan Bird, Southwest program director for Defenders of Wildlife. “This court ruling recognizes the urgent need from the U.S. Fish and Wildlife Service to develop a recovery plan that addresses a significant threat to the Mexican gray wolf: poaching by people.”

“This court ruling is timely and important for securing a bright future for the critically endangered Mexican gray wolves. Recent research shows that human-caused mortality of these rare wolves, especially through poaching during times of reduced protection, has been consistently mismeasured and significantly underestimated,” said plaintiff David Parsons, the former Mexican wolf recovery coordinator for the Fish and Wildlife Service.

“Too many wolves, including individuals released from our center, have already been killed by poachers,” said Maggie Howell, director of the Wolf Conservation Center. “This ruling confirms the critical need for the U.S. Fish and Wildlife Service to take meaningful action to protect these vulnerable and genetically invaluable wolves.”


Mexican gray wolves, or lobos, are one of the most endangered mammals in North America and are also the most genetically distinct lineage of wolves in the Western Hemisphere. By the mid-1980s, federal hunting, trapping and poisoning on behalf of the livestock industry had caused the extinction of lobos in the wild, with only a handful remaining in captivity.

Poaching causes the deaths of more Mexican gray wolves than any other cause, with 105 wolves known to have been killed unlawfully between 1998, when reintroduction to Arizona and New Mexico began, and 2019. A similar number of radio-collared wolves disappeared, many under suspicious circumstances, during this same span.

With fewer than 250 lobos left in the wild, this critical decision will now spur the new administration to produce a recovery plan that adequately addresses the needs of the wolves and the need to protect biodiversity during an extinction crisis.
