A federal court on Tuesday removed an obstacle to the U.S. government’s plan to release more endangered wolves in New Mexico over the state’s objections, but it was not clear whether additional animals would be reintroduced under the Trump administration.

The Denver-based 10th U.S. Circuit Court of Appeals lifted a temporary order issued by a lower court that stopped the U.S. Fish and Wildlife Service from releasing more Mexican gray wolves after New Mexico refused to agree to the plan.

The state Game and Fish Department is disappointed, but it will keep pursuing the case in federal court in New Mexico, where it was originally filed, spokesman Lance Cherry said. Fish and Wildlife spokesman Jeff Humphrey said the agency was still reviewing the decision.

Despite the ruling, it wasn’t immediately known whether wolf releases would resume. President Donald Trump has slowed or reversed other environmental initiatives since taking office in January, when the appeals court was considering the wolf case.

And many Republicans in control of Congress have long objected to parts of the Endangered Species Act, which is the legal authority for re-establishing the Mexican gray wolf and other animals.

Protected status under the act usually brings restrictions on ranching, mining and other activities.

Only about 110 Mexican gray wolves live in the wild. They nearly disappeared in the 1970s, and the federal government added them to the endangered species list in 1976. The Fish and Wildlife Service began reintroducing them to parts of their original range in New Mexico and Arizona in 1998.

New Mexico has complaints about the way the program is managed, and in 2015 it refused to issue a permit to Fish and Wildlife to release more of the predators.

The agency decided to release them anyway, citing an urgent need to expand the wild population to prevent inbreeding. New Mexico officials went to court, and a federal judge temporarily blocked further releases last year while the dispute is resolved.
