PHOENIX -- A cooperative effort to restore habitats along the Lower Colorado River Basin is seeing the re-emergence of several threatened and endangered species.

The Central Arizona Project (CAP) is part of a program, begun in 2005, that has reclaimed or restored more than 1,100 square miles of wetlands and woodlands along the river.

The Lower Colorado River Multi-Species Conservation Program (MSCP) is designed to protect 27 species, including eight listed under the Endangered Species Act.

Chuck Cullom, Colorado River programs manager for the Central Arizona Project, said the 50-year project is a joint effort between Arizona, California and Nevada.

"We do that so that the species have a chance to recover from the impacts of building dams and operating diversions in the Lower Colorado River," Cullom explained. "We're paying the environment back for the service the river provides."

Cullom pointed out the program has created more than 6,500 acres of conservation habitat, planted thousands of cottonwood willows and honey mesquite trees, and has restocked the river with more than one million native fish.

He added restoring the habitat is part of the CAP's agreement with the U.S. Bureau of Reclamation, and he noted the program works much better when the states work together.

"Rather than the service coming in and saying, 'You need to do this and that,' we've spent about seven years negotiating with all the water users in the Lower Basin to figure out how to do this cooperatively," Cullom recounted.

Cullom emphasized the program has already seen the resurgence and return of several of the species it is designed to protect, including the "rediscovery" of the Northern Mexican garter snake, which has not been seen in the river basin for decades.

"We're learning a lot about these rare species because of the program and because we're learning about them, we can enhance their chance of long-term survival," Cullom asserted.

The program operates through funding provided by the U.S. government and from water and hydropower users in California, Arizona and Nevada. There are more than 30 participants in Arizona, including the CAP, which is the largest single contributor in Arizona.

Wyoming's practice of feeding elk over winters is a century old but the spread of disease has increased concerns. Now, the Greater Yellowstone Coalition is rolling out a new solution.

The group launched a voluntary program in 2019, incentivizing ranchers who live near elk feedgrounds to ship their cattle elsewhere during winters, allowing elk to roam on their native winter range instead.

It keeps cattle and elk from commingling, which can lead to the spread of dangerous diseases such as brucellosis and Chronic Wasting Disease.

Teddy Collins, Wyoming conservation associate for the Greater Yellowstone Coalition, said the program is beneficial to the elk and cattle ranchers.

"It is very timely to have these agreements as a tool in the toolbox for state wildlife officials to try and move away from this process that has been around for a hundred years, but has negative repercussions," Collins emphasized.

Collins noted Chronic Wasting Disease was detected in four of the state's 21 feedgrounds this winter. A rancher in Lincoln County signed on in the fall, adding to the two agreements Teton County ranchers have signed since 2019.

The agreements are tailored to each rancher. Generally, cattle leave the property for more temperate areas of Wyoming or Utah from around Dec. 1 to April 1. The Greater Yellowstone Coalition shares associated costs with producers.

"These are voluntary agreements and they are incentive-based," Collins explained. "Each agreement is unique to the needs and the topography and the business of the individual producer."

Producers are, he added, "quite satisfied" with the program so far.

Minnesota bird enthusiasts should keep their binoculars handy. April is a good month to spot various species migrating back to the region. Experts have tips on making it easier for them to settle in.

A good place to start for "birding" during spring migration is the Mississippi River corridor, a key flyway for birds traveling between their winter and summer homes. In the greater Duluth area, folks might also notice a lot of raptors, such as hawks and eagles, this time of year.

Monica Bryand, executive director of the Urban Bird Collective in the Twin Cities, considers this a worthwhile and fun activity.

"I've only been a birder for over 20 years, and I didn't realize what was out there until somebody took me birding," she said, "and, of course, now I'm just absolutely hooked."

As birds fan out across the state, Bryand says residents can do their part to keep obstacles and threats out of the way. That includes limiting backyard time for outdoor cats. And since birds tend to migrate at night, dimming or turning off outdoor lights is helpful, so long as personal safety isn't compromised. Applying window treatments such as films with UV patterns reduces bird strikes.

The latest State of the Birds report from national science and conservation groups is out, showing continued population declines, especially for grassland birds.

Bob Dunlap, a zoologist and data specialist for the Minnesota Department of Natural Resources, said that aligns with his research.

"We're down to 1% or less of the original prairie in Minnesota," he said, "and over time, that's definitely going to take a toll on these birds that do need grasslands to survive."

Researchers, along with the nonprofit Friends of the Mississippi River, have noted that habitat restoration has allowed species such as the Henslow's sparrow to see a turnaround. Meanwhile, Dunlap encouraged birders to use the "e-Bird" app when they're out. He called a reliable tool for citizen scientists to enter sightings.

"And so, the more data we have," he said, "the better to keep track of some of these trends."

Rep. Lauren Boebert, R-Colo., has introduced a bill to remove gray wolves from the list of endangered and threatened species under the Endangered Species Act.

The measure would also prohibit any challenges to the law in court.

Jewel Tomasula, national policy director for the Endangered Species Coalition, said H.R. 845 is essentially recycled legislation.

"The bill would reinstate a U.S. Fish and Wildlife Service delisting decision issued in November of 2020, the end of the first Trump administration," Tomasula explained. "This was overturned in court because the Fish and Wildlife Service did not use the best available science, among other serious errors."

The move comes as President Donald Trump and allies have accused federal courts of trying to overtake the executive branch's authority by blocking a number of executive orders.

After being hunted and poisoned to near extinction, the return of the gray wolf to the Lower 48 states is widely viewed as one of America's greatest conservation success stories. The livestock industry, which has overtaken large swaths of historic wolf habitat for grazing, has opposed protections citing concerns about predation.

A separate bill aims to put the brakes on getting species listed as endangered, speed up the delisting process and remove guardrails meant to prevent species from becoming extinct.

Kaitie Schneider, Colorado wolf representative for Defenders of Wildlife, said preventing the loss of keystone species like gray wolves is important for maintaining ecosystem viability and resilience in the face of a changing climate.

"We know that it's better not to lose that piece of the puzzle to begin with," Schneider stressed. "But it's critically important to put it back where we can. Keeping our ecosystems intact and restoring native species is not only important for us, but for our future generations too."

Nine in 10 Democrats and eight in 10 Republicans support the Endangered Species Act. And 84% of Americans support returning wolves to suitable landscapes in the Lower 48.

Schneider noted states like Colorado are showing wolves and people can coexist.

"If these bills and efforts to delist wolves from the Endangered Species Act federally do go through, that's not going to stop the wolf reintroduction to Colorado," Schneider asserted. "Because the voters of Colorado decided that this is a priority for our state. That's going to continue."
