PHOENIX - Mexican gray wolf numbers are dropping in Arizona and New Mexico, down 20 percent in the past year. The 42 remaining endangered wolves are part of a reintroduction program that began in 1998.

Dr. Rich Fredrickson, a University of Montana wildlife biologist, says the falling numbers threaten the genetic diversity needed for the wolf packs to become self-sustaining, because many pups seeking to mate are closely related.

"So when those pups grow up and they look for mates, it's going to be hard for them to find a mate that's not closely related to themselves. And the likely result of this is that the fitness of the Blue Range population is going to decline with time."

Fredrickson says the U.S. Fish and Wildlife Service, which manages the reintroduction program, needs to develop a science-based recovery plan with explicit attention to genetic management and goals. For his part, Fish and Wildlife Service Regional Director Benjamin Tuggle pledges to find the reasons for the wolves' decline, and reverse it.

Fredrickson says one strategy, known as genetic rescue, would introduce genetically unrelated wolves into the Arizona-New Mexico border region.

"These immigrants bring increased fitness of the overall population, and that fitness increase can last for several generations after the immigrants themselves are dead and gone."

He sees the gray wolf recovery effort as part of the commitment society made when President Nixon signed the Endangered Species Act in 1973.

"The Endangered Species Act requires the federal government to do their best, to recover endangered species to levels where they can survive without strong intervention."

Some ranchers have opposed reintroduction because of instances in which wolves have killed livestock or pets. Conservation groups have responded with fencing projects, mounted patrols and reimbursement for losses.

RALEIGH, N.C. - A bipartisan bill to protect wildlife species before they're imperiled has gained the support of North Carolina's senators. It's the first state to have both senators sign on, along with eight other senators.

The Recovering America's Wildlife Act would direct $1.4 billion to state and local agencies to prevent species from becoming endangered. It would direct about $24 million to North Carolina.

Tim Gestwicki, CEO of the North Carolina Wildlife Federation, called it the "most historic piece of wildlife conservation legislation in the past half-century."

"We are absolutely over-the-moon delighted that both of our senators have joined as sponsors, Senator Burr and Senator Tillis," said Gestwicki, "demonstrating North Carolina leads the way once again."

The House version has six cosponsors from North Carolina, including Republicans and Democrats.

Gestwicki said the bill would help almost 500 species of concern in the state. They include the Carolina northern flying squirrel, Appalachian cottontail and zigzag salamander.

Collin O'Mara, president and CEO the National Wildlife Federation, said it's a critical time for legislation like this, with more than one third of all wildlife species at heightened risk of extinction across the country.

O'Mara said he believes Tar Heel State support in Congress could be critical for the bill's chances.

"When this bill passes," said O'Mara, "the North Carolina stamp of approval will be one of the reasons why it gets to the president's desk."

O'Mara said it's heartening to see bipartisan support for this measure.

"We often joke that there's no such thing as a Republican trout or a Democratic deer," said O'Mara. "And this is a moment that's showing that wildlife conservation, and conservation more broadly, can still truly be one of the bipartisan issues in this Congress."

CHEYENNE, Wyo. -- A federal court agreed with conservationists this week, ordering winter feeding of elk on the Bridger-Teton National Forest requires additional environmental review.

The court ruled that two feedgrounds were not properly permitted, in part because the U.S. Forest Service had not evaluated the potential for disease transmission when large numbers of animals congregate in close quarters.

Connie Wilbert, director of the Sierra Club Wyoming Chapter, explained the growing concern.

"Chronic wasting disease has now been documented in mule deer and elk right around these feedgrounds," Wilbert reported. "It's literally on the doorstep."

Chronic wasting disease affects the central nervous system of deer, elk and moose, and is always fatal.

Wyoming's powerful livestock industry pushed to keep winter feedgrounds as a tool to mitigate against encounters with wildlife in low-elevation ranges, and to protect hay stores. Some outfitters also see feedgrounds as a way to keep herd numbers high.

Wilbert countered reliance on feedgrounds is both outdated and risks outbreaks of chronic wasting disease throughout the Yellowstone ecosystem, which could wipe out entire herds.

She noted there are proven alternatives, including fencing, to keep elk away from hay stores.

"They want to reduce competition from wildlife for forage," Wilbert contended. "And it's important to know that a lot of that is on public land, and we believe that wildlife should be allowed to access historic winter range."

The court found the Forest Service improperly permitted feeding elk at Alkali Creek and Dell Creek, and the claims made by the agency in defending its decisions were "implausible" and "unreasonable." The court also ruled feeding must stop at Dell Creek, which has been operating without a valid permit since 2017.

MONTEREY BAY, Calif. - This week, conservation groups are celebrating Sea Otter Awareness Week with online and in-person events across the state.

Historically, the Pacific Rim supported between 150,000 and 300,000 sea otters, but the population is now estimated at about 106,000.

Andrew Johnson, California representative with the nonprofit Defenders of Wildlife, said 16,000 endangered southern sea otters once roamed the California coast. Now, only about 3,000 animals are left, mostly between Santa Barbara and San Francisco.

"But they're still struggling," said Johnson. "Their numbers are stagnant. They aren't expanding their range north or south, and haven't for the last two decades."

Great white sharks are a threat to the sea otter. But Johnson said human activity does more harm, especially the pollutants and agricultural runoff that end up in the ocean.

You can check out the list of sea otter events this week online, at 'Defenders.org.'

Sea otters were all but wiped out from Northern California waters during the fur trade of the 1800 and 1900s.

Johnson said sea otters are a keystone species - without them, the ecosytem is thrown out of balance. And climate change is warming the ocean, exacerbating the problem.

"Over the last seven or eight years with the warming ocean waters, the so-called 'blob' along the West coast," said Johnson, "sea star die offs, urchin overgrowth, overgrazing on kelp - the system along our shoreline in California is in a rough spot."

Conservation groups are hoping to expand a successful program pioneered at the Monterey Bay Aquarium, where biologists rescued abandoned or orphaned sea otter pups, raised them with a surrogate mother, and released them into Elkhorn Slough.

In the future they hope to jumpstart new colonies in Northern California.
