LOS ANGELES - Prompted by the discovery of a mountain lion known as P-22 in L.A.'s Griffith Park, wildlife advocates say now is the time to build a wildlife passageway over the 101 freeway.

When it was built in the late 1950s, few planners were aware the route through Liberty Canyon was one of Southern California's most important wildlife corridors, linking the Simi Hills to the Santa Monica Mountains. Over the years, the area has been the site of dozens of collisions between motorists and animals.

Beth Pratt, California Director of the National Wildlife Federation, says mountain lions, bears, bobcats and other wildlife need large areas of habitat to survive, and L.A.'s maze of freeways has hemmed large animals into smaller and smaller areas.

"National Park Service scientists have been looking at this issue," she says. "They've collared over 30 cats, and they're getting a pretty good idea of how they move. They've been able to identify this pinch-point on the 101 freeway. They have over 60,000 GPS points showing the mountain lions going up to the 101, and turning around."

But some mountain lions do try to cross at Liberty Canyon, and elsewhere along the 101, and many are hit and killed - similarly endangering drivers.

Pratt says major highways like the Ventura Freeway are a challenge not only because mountain lions keep getting hit by cars, but the abundance of freeways also leads to reduced genetic diversity, and even inbreeding among wildlife in the region.

She says with such an extraordinary amount of urbanization along on the edge of wildlands in Los Angeles, wildlife crossings are one way damage done to wildlife populations can begin to be repaired.

"What it's really doing is restoring balance to an ecosystem that, because of these freeways cross-cutting it, is not there right now, " she says. "You have animals existing on islands of habitat, and that's not good for the Santa Monica Mountains as a whole."

While the design is expected to mirror similar projects already built in the Netherlands, Banff National Park in Alberta, and on the Flathead Reservation in Montana, the Los Angeles crossing has the potential to be the largest wildlife crossing in the world.

"For L.A., that would just show wonderful leadership," says Pratt. "L.A. is sometimes unfairly tagged as a bad environmental player, but if L.A. were to become the site of the largest wildlife crossing in the world - what a statement."

Pratt notes the active and supportive involvement of the California Department of Transportation has been a significant factor in moving the proposed crossing project forward.

Following the torture of a wolf by a Wyoming man, a state panel is seeking a bill to protect the killing of predators with vehicles, but Federal lawmakers are pushing back.

After Cody Roberts in February hit a gray wolf with his snowmobile, taped its mouth shut and brought the injured animal to a bar, he was fined just $250 and an international outcry followed.

The gray wolf was removed from the federal endangered species list in 2021. In Wyoming, it is considered a "predator" and is legal to kill. The state's newly formed Treatment of Predators Working Group approved a bill, which clarified using vehicles to run over "predators," a practice called "whacking," is legal, as long as all "reasonable efforts to kill" the injured animal are then taken.

Elaine Leslie, retired agency chief of biological resources for the National Park Service, said Wyoming "sanctions this kind of behavior."

"The dialogue during that meeting was focused on, 'Oh, we can't identify or articulate the exact meaning of the word humane or ethical. So let's take that out of the bill,'" Leslie recounted.

In an opposing move, Rep. Nancy Mace, R-S.C., last week introduced a bill to prohibit the intentional use of motor vehicles to harm wildlife on federal lands, establish a protocol for enforcement and penalties and maintain exemptions for human safety.

The bill is co-sponsored by legislators in North Carolina, Florida and Louisiana but notably none in the Mountain West, where the practice of "whacking" coyotes and wolves is legal in several states, as a practice distinct from hunting.

Leslie pointed out the behavior is likely happening elsewhere, too.

"We have no idea what the extent of this behavior is nationally," Leslie acknowledged. "I think it does need to have national attention and be a national bill right now."

A Wyoming legislative committee will hear recommendations from the Treatment of Predators Working Group Sept. 30.

Two conservation groups have filed suit in a federal court in Montana to stop a U.S. Forest Service logging project that would clear cut large stands of trees, and carve over 24 miles of new logging roads into the Bitterroot National Forest.

The Forest Service says this is the most efficient way to manage the old growth forest.

But Alliance for the Wild Rockies Executive Director Mike Garrity said the Forest Service's plan for logging on the Gold Butterfly project threatens critical habitat for a host of species, because it leaves only eight trees standing on each acre of old growth forest in the project area in the Bitterroot.

"Eight trees on an area a little bigger than a football field," said Garrity. "Nobody would call that an old-growth forest. Old-growth forests are very thick forests with big trees, younger trees, standing dead trees, and fallen over trees."

The Forest Service says based on an Environmental Impact Statement, the Gold Butterfly project is the best and most efficient way to manage old growth in the Bitterroot.

The suit awaits action in a U.S. District Court in Missoula.

Garrity said the Forest Service's logging plan to leave that part of the Bitterroot so barren threatens habitats of the pileated woodpecker, pine martin and goshawk, among others.

"There are also grizzly bears in the area," said Garrity. "There was a successful wolverine den there recently, where the wolverine produced kits. Both are listed as threatened under the Endangered Species Act."

The groups that filed the suit are asking the federal court to rule the project illegal.

They offer the opinions of over 3,000 people who weighed in against the project as evidence that the public doesn't want any more logging roads in old-growth forests.

Groups in Oregon are warning wolf poaching poses a threat, not just to the creatures targeted but to people who enjoy the outdoors.

Poaching was a big issue in 2023 and again this year, especially through poisoning.

Bethany Cotton, conservation director for nonprofit conservation organization Cascadia Wildlands, said the wolf population did not grow in 2023 for the first time since the species returned to the state and a high rate of deaths has continued in 2024, largely caused by humans.

In May, the Oregon Department of Fish and Wildlife started warning recreationists to keep their dogs on leashes because of potential exposure to poisoning meant to illegally kill wolves.

Cotton noted she decided against visiting eastern Oregon because of it.

"I have two rescue dogs, and I was invited to some friends' property out there and to spend some time out there this summer and I chose not to go," Cotton recounted. "Because it's too high a risk to go camp or hike in that part of the state right now knowing that this is happening."

Cotton acknowledged the investigation into a wolf's death takes time but poisonings are indiscriminate. In February, a poisoned cow carcass in Hells Canyon National Recreation Area killed three wolves, two golden eagles, a mountain lion and a coyote. The poaching led to the Department of Fish and Wildlife's May warning. The wolf count was 178 at the end of 2023.

Groups have banded together to take on poachers with the Turn-In-Poachers program. The collaboration is between O-D-F-W, the Oregon State Police, the Oregon Hunters Association, the Oregon Wildlife Coalition, the Oregon Outfitter and Guides Association and the Oregon State Marine Board. Rewards have been offered for tips on poachers but have not led to any arrests or convictions.

Cotton wants to see the silence around poaching events broken.

"We really do hope that those with knowledge about this poisoning incidents or future poisonings will come forward because of the possibility and the reality that it impacts far more than wolves," Cotton emphasized. "It impacts lots of other species and has impacted dogs and very likely will again in the future."

Cotton added healthy wolf populations are good for humans, including controlling diseases like chronic wasting disease in deer and elk and reducing vehicular accidents with deer.

"They bring a lot of benefits to the landscape," Cotton stressed. "It's been a huge success story that wolves naturally recolonized Oregon after having been absent for so many decades, and we just need to really learn to coexist with them like humans and wolves did for millennia."
