WASHINGTON (AP) — A federal judge on Tuesday threw out a host of actions by the Trump administration to roll back protections for endangered or threatened species, a year after the Biden administration said it was moving to strengthen species protections weakened under former President Donald Trump.

U.S. District Judge Jon Tigar in Northern California eliminated the Trump-era rules even as two wildlife agencies under President Joe Biden are reviewing or rescinding the Trump-era regulations. The decision restores some protections under the Endangered Species Act while the reviews are completed.

Environmental groups hailed the decision, which they said speeded up needed protections and designation of critical habitat designations for threatened species, including salmon in the Pacific Northwest.

Tigar's ruling "spoke for species desperately in need of comprehensive federal protections without compromise," said Kristen Boyles, an attorney for the environmental group Earthjustice. "Threatened and endangered species do not have the luxury of waiting under rules that do not protect them."

The court ruling comes as two federal agencies — the U.S Fish and Wildlife Service and National Marine Fisheries Service — review five Endangered Species Act regulations finalized by the Trump administratio n, including critical habitat designations and rules requiring federal agencies to consult with other agencies before taking action on threatened or endangered species.

Fish and Wildlife also said it will reinstate the so-called "blanket rule," which mandates additional protections for species that are newly classified as threatened. Those protections were removed under Trump.

Critical habitat designations for threatened or endangered species can result in limitations on energy development such as mining or oil drilling that could disturb a vulnerable species, while the consultation rule, and a separate rule on the scope of proposed federal actions, helps determine how far the government may go to protect imperiled species.

Under Trump, officials rolled back protections for the northern spotted owl, gray wolves and other species, actions that Biden has vowed to review. The Biden administration previously moved to reverse Trump's decision to weaken enforcement of the century-old Migratory Bird Treaty Act, which made it harder to prosecute bird deaths caused by the energy industry.

The decision on the bird law was among more than 100 business-friendly actions on the environment that Trump took and Biden wants tp reconsider, revise or scrap.

A spokesman for the Interior Department, which oversees the Fish and Wildlife Service, said the agency is reviewing the decision.

Fish and Wildlife, along with the marine fisheries service, announced in June 2021 that they were were reviewing the Trump-era actions. The reviews could take months or years to complete, officials said.

Industry groups and Republicans in Congress have long viewed the Endangered Species Act as an impediment to economic development, and under Trump they successfully lobbied to weaken the law's regulations. Environmental groups and Democratic-controlled states battled the moves in court, but many of those cases remained unresolved.

Ryan Shannon, a lawyer with the Center for Biological Diversity, another environmental group, said he was "incredibly relieved" that "terrible" Trump-era rules governing the Endangered Species Act were thrown out by the Oakland, Calif.-based Tigar, who was appointed to the federal bench by former President Barack Obama.

"I hope the Biden administration takes this opportunity to strengthen this crucial law, rather than weaken it, in the face of the ongoing extinction crisis,'' Shannon said Tuesday.
