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.

As its 125th anniversary nears, the Connecticut Audubon Society has released a report detailing the effectiveness of conservation efforts in the state.

The 2022 "State of the Birds" report found bald eagles making a strong comeback and nesting in numerous towns across the state. It also detailed how ospreys are nesting, thanks to nesting boxes placed throughout the state.

Tom Andersen, communications director for the Connecticut Audubon Society said there have been some challenges with keeping these species around - and one is simply a matter of habitat.

"Shore birds, like the American Oystercatchers, when they're in Connecticut, they rely exclusively on beaches, and there are not all that many beaches in Connecticut," he said. "The Connecticut shoreline is not that long, not all of it is beach - and most of it is used by people, for recreation."

He said these birds, which are vulnerable to disturbances, must learn how to successfully coexist alongside humans in these landscapes. He said he hopes the few undisturbed places where birds are thriving remain that way.

As the group celebrates this milestone anniversary, there's still plenty of work to be done to keep bird species off endangered-species lists. Andersen said some work can be done locally, but a large part needs to begin at the federal level. He said he thinks passing the Recovering America's Wildlife Act would boost any state's conservation efforts, and described what passage of the bill would mean.

"It would direct about $1.3 billion annually to all of the states in the United States and to Indigenous peoples, so they can implement their Wildlife Action Plans, which are congressionally mandated," he said. "Connecticut alone would receive about $12.5 million each year from the fund."

The bill has bipartisan support, including four U.S. House members from Connecticut and U.S. Sen. Chris Murphy, D-Conn. The Audubon Society has future plans for land acquisition to preserve bird habitat and wetlands. Andersen said the group is using this anniversary as a showcase for the beginnings of the conservation movement in the United States.

Wildlife biologists are warning Iowa hunters to have their deer tested for a deadly condition known to attack the animal's brain.

Chronic Wasting Disease has been on the rise. It causes spongelike holes to appear in the brain, and is present in up to half of the deer herds in parts of Wisconsin, which does not bode well for other Midwestern states.

Jace Elliott, state deer biologist for the Iowa Department of Natural Resources, said the disease is 100% fatal and has the potential to alter the density and gender balance of the deer population in Iowa.

"More importantly, perhaps, really alter the deer quality that we have in Iowa," Elliott pointed out. "Iowa is known as a trophy whitetail destination, and there's really a lot of interest in out-of-state hunters coming here to hunt deer just because of our well-managed deer herd."

Elliott said Chronic Wasting Disease is on the rise in Iowa and since there is no known cure, it will continue to grow. He stressed it is important for hunters to get their harvested deer tested by game officials, free of charge.

While there have only been a few cases of the disease confirmed in Iowa so far, Elliott noted officials know it spreads quickly. If part of the herd becomes infected, the disease will grow exponentially among the animals in a specific geographic area.

"The disease is spreading, and we don't expect it to stop spreading," Elliott acknowledged. "What we're really just trying to do is slow the spread as long as we can, until science can catch up and give us some other options for managing the disease."

Chronic Wasting Disease has not been proven to be a threat to humans if people consume infected venison. But out of an abundance of caution, the Centers for Disease Control and Prevention warns against eating the meat before it has been proven free of the disease.

After receiving input from stakeholders earlier this year, the Wyoming Game and Fish Department has released a list of priorities guiding its initial draft of a management plan for the controversial practice of feeding wild elk at winter feedgrounds.

Kristin Combs - executive director of Wyoming Wildlife Advocates - agreed with much on the list, but said she worries the emphasis on maintaining unnaturally large big-game populations could compromise herd health.

She said it's important to make space in the plan for elk's natural predators.

"The one thing we don't see in the list," said Combs, "is having a robust suite of predators and large carnivores on the landscape that can really offer free services to provide for healthy elk herds."

She said allowing predators to kill off animals that fall sick to chronic wasting and other communicable diseases will limit the risk of hunters harvesting diseased meat, and strengthen biodiversity and the region's ecosystems.

Some hunters support using feedgrounds to maintain large elk populations, and outfitters see the practice as a proven way to keep doors open for business.

Game and Fish says it expects to publish the proposal after internal review, and will accept public comments in coming weeks.

The powerful ranching lobby has urged the agency to limit conflicts between cattle and elk, in part over fears of disease transmission, and that priority made the list.

Combs noted that other western states including Colorado, Idaho and Montana that do not use feedgrounds place part of the burden of limiting conflict on ranchers.

"Fencing out elk is a requirement, or fencing in your hay stores," said Combs. "Keeping your herd separated from elk is a part of the responsibility of raising cattle, versus having the government do this for you."

Another priority is to modify feedground management to minimize disease transmission. Combs said the very nature of feedgrounds, where animals are packed together in close quarters, practically invites large-scale infections.

But she agreed with the agency's goal of helping elk transition to natural winter ranges.

"There's already a bunch of really good wild foraging areas," said Combs, "especially on the national forests, even on some private lands that are available."
