SEATTLE -- The perils of traffic aren't just a human concern. Wildlife advocates say animals need highway crossings to survive.

Mitch Friedman's organization Conservation Northwest was integral in developing a wildlife crossing project on I-90 east of Snoqualmie Pass.

"If we don't provide ways for wildlife to get under or over our roads and highways in the places that they need to cross, then we end up with smashed cars, injured drivers and dead wildlife," Friedman said.

As Congress considers a major transportation bill, Friedman said he's eyeing the Wildlife Crossing Pilot Program. It would provide $250 million in grants over five years to states, tribes and local governments for wildlife infrastructure projects.

Friedman noted these projects also would provide jobs at a time when unemployment numbers are high.

Beth Pratt is regional executive director of the National Wildlife Federation in California. She's part of an effort to build the largest wildlife crossing in the world over 10 lanes of Highway 101 in Los Angeles.

But Pratt noted crossings have to do more than get animals across highways.

"No matter what site you're using, the animals have to feel comfortable going over it," Pratt said. "They have to feel comfortable approaching it and they have to feel comfortable, obviously, when they get off it that you're leading them into ground that feels safe."

Pratt said without the LA project and others, species such as cougars face a serious challenge crossing highways.

"At worst, [it] could prove not just deadly for one animal but actually hasten the extinction of local populations of wildlife," she said.

Friedman with Conservation Northwest said he used to worry that wildlife crossings would be controversial.

"The public generally supports these things and I've yet to see a backlash against taxpayer investment in providing wildlife crossings to make our highways safer," he said.

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.

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.

TUCSON, Ariz. - The battle against copper mining the Santa Rita Mountains outside of Tucson continues - even though the feds just handed a victory to environmental groups.

The U.S. Fish and Wildlife Service just rejected a bid by a Canadian mining company, Hudbay Minerals, to remove critical-habitat designation for jaguars from 50,000 acres - the proposed site of the company's open-pit Rosemont mine.

Gayle Hartmann, president of the nonprofit Save the Scenic Santa Ritas, said Hudbay now plans to explore the other side of the mountain - the west side.

"The biggest problem on the west side is that it's largely not public land, it's private land," said Hartmann. "It's their mining claims, and they have bought more private land. So, they're trying to avoid federal law by sticking to their private lands."

In 2019, Hudbay lost a court case that halted preparations for the Rosemont mine, but that is now under appeal. The company, which did not respond to a request for comment by deadline, has invested tens of millions of dollars in its mining claims in the Santa Rita Mountains.

Hartmann said she wants to see the area returned to the Coronado National Forest in pristine condition.

"What we're looking forward to ultimately is that there would be sufficient funds," said Hartmann, "through the Land and Water Conservation Fund, perhaps - to buy out their private land and turn this back into a national forest without mining claims on it."

Only a handful of jaguars still remain in the mountains of southern Arizona. Sportsmen and ranchers have hunted them almost to extinction.

The area is considered an important wildlife corridor to lure the Mexican jaguar population back into their historic range.

Robert Peters, southwest representative for Defenders of Wildlife, said he sees jaguars as an iconic part of the American West.

"They're a charismatic, vital part of our natural heritage that was lost," said Peters. "And it's essential that we reintroduce top predators, like the Mexican wolf and the jaguar, because they're key components to keeping ecosystems functioning well."

Peters coauthored two recent scientific papers on jaguars - one on the feasibility of reintroducing them in Arizona, and one that identifies 20 million acres of possible jaguar habitat in Arizona, much of it north of Interstate 10.
