BILLINGS, Mont. -- Federal officials have dropped plans to conduct a five-year status review of a jeopardized bird species as the Trump administration seeks to weaken its habitat protections.
The U.S. Fish and Wildlife Service said in 2015 that the greater sage grouse was not a threatened or endangered species but pledged to revisit the issue in five years.
Spokeswoman Jennifer Strickland told The Associated Press the agency is not legally required to complete a review, which can be a first step toward determining if greater protections are needed.
Strickland says the agency instead will work with state wildlife officials to document the effectiveness of conservation plans for the bird.
The Trump administration on Thursday advanced a proposal to overhaul those conservation plans and lift restrictions on oil and gas drilling in grouse habitat.
The Trump administration is advancing plans to ease restrictions on oil and gas drilling and other activities on huge swaths of land in the American West that were put in place to protect an imperiled bird species.
Land management plans released Thursday would allow more waivers for drilling to encroach into the bird's habitat.
That would reverse protections for greater sage grouse enacted in 2015, under President Barack Obama. Critics warn it could doom the birds.
Trump and Interior Secretary Ryan Zinke have vowed to open more public lands to drilling. Grouse protections have long been viewed by companies as an obstacle to development.
The ground-dwelling birds are known for an elaborate mating ritual and range across portions of 11 states. Habitat loss and disease have decimated some populations.
The Trump administration moved forward Thursday with plans to ease restrictions on oil and natural gas drilling, mining and other activities across millions of acres in the American West that were put in place to protect an imperiled bird species.
Land management documents released by the U.S. Interior Department show the administration intends to open more public lands to leasing and allow waivers for drilling to encroach into the habitat of greater sage grouse.
Critics warned the changes could wipe out grouse colonies as drilling disrupts breeding grounds. Federal officials under President Barack Obama in 2015 had adopted a sweeping set of land use restrictions intended to stop the birds' decline.
Interior Deputy Secretary David Bernhardt said the agency was responding to requests by states to give them more flexibility in how public lands are managed. He said the goal to conserve sage grouse was unchanged.
"I completely believe that these plans are leaning forward on the conservation of sage grouse," Bernhardt told The Associated Press. "Do they do it in exactly the same way, no? We made some change in the plans and got rid of some things that are simply not necessary."
The changes drew a sharp backlash from conservation groups and wildlife advocates, who warned excessive use of drilling waivers could push sage grouse onto the list of threatened and endangered species.
"If you allow exception after exception, that might make sense for a particular project in a particular spot, but you add them all together and you have death by a thousand cuts," said National Wildlife Association vice president Tracy Stone-Manning.
The ground-dwelling grouse ranges across about 270,000 square miles in parts of 11 Western U.S. states and two Canadian provinces. Its numbers plummeted in recent decades.
Under President Donald Trump, Interior Secretary Ryan Zinke has vowed to lift obstacles to drilling, and grouse protections have long been viewed by the energy industry as an obstacle to development.
The new plans remove the most protective habitat designations for about 13,000 square miles of public land. Those areas, considered essential to the species' survival, were a centerpiece of the Obama policy. The Trump administration also wants to drop some requirements to prioritize leasing for oil and gas outside sage grouse habitat.
Utah Gov. Gary Herbert, a Republican, said Thursday announcements showed federal officials heeded the state's desire for changes to the 2015 plans.
"This is a great example of federal leaders listening to state leaders, valuing their expertise, and changing their plans based on that input," Herbert said in a statement.
Sage grouse are large, ground-dwelling birds known for an elaborate mating ritual in which males strut around breeding grounds with large, puffed-out air sacs protruding from their chests.
They once numbered in the millions. The U.S. Fish and Wildlife Service now estimates the population at 200,000 to 500,000. Energy development, disease and other causes have decimated populations in some areas.
The Trump administration's proposal would reverse or modify the Obama-era protections in seven states — Wyoming, Nevada, Utah, Colorado, California, Idaho and Oregon.
The oil and gas industry chafed at the old rules. Once Trump took office, industry representatives lobbied the administration to give more recognition to changes in drilling practices that reduce how much land is disturbed for wells.
"We can do both — protect sage grouse and move forward with responsible energy development," said Kathleen Sgamma with the Western Energy Alliance, which represents more than 300 oil and gas companies. "We've reduced the size of well pads, reduced the numbers of wells. And we had done all these things and the prior administration assumed development was taking place like it was 20 years ago.
Governors from several western states previously raised concerns over a related federal directive from the Bureau of Land Management that would limit a type of land swap that can be used to preserve habitat for the birds.
Without land swaps and related forms of compensation meant to offset habitat damage, the governors said it would be harder to help the sage grouse survive.
In response, the Interior Department on Thursday revised the directive to say federal officials would consider state-mandated or voluntary proposals for land swaps or similar offsets, but would not accept cash payments.
"Where there's a state requirement, we require in our permits that they comply with state requirements," Bernhardt said.
Colorado officials were encouraged by the new directive.
"It allows them to mirror what we're asking for," said John Swartout, a policy adviser to Colorado Democratic Gov. John Hickenlooper.
He added that Colorado pushed for the revision for a year and said state and federal officials will likely sign an agreement by the end of the month on how to implement the new directive.
Following Thursday's release of environmental studies analyzing the changes in each state, governors and the public get another chance to weigh in before a final decision is expected in early 2019.
