A new study shows since 1970, more than 80% of the global populations of freshwater migratory fish have declined significantly. The report calls developments in its Living Planet Index "distressing," and faults habitat loss and degradation. It says factors like river fragmentation due to dams, and agricultural encroachment, account for half of the threats.

Michele Thieme, deputy director of freshwater for the World Wildlife Fund, monitors freshwater species, and said though the trend is heading downward, there are efforts underway to save these species.

"On average, we've seen freshwater migratory fish populations in North America decline by 34% since 1970. This is a little bit lower within what we're seeing globally, but it's still not a good number," she said.

The Index follows more than 1,800 populations of 284 native, migratory freshwater fish species from around the world. Thieme said these fish often make the difference in food security and nutrition for vulnerable communities, while supporting the livelihoods of millions in local and recreational fishing industries and global trade.

Thieme added despite the bad news, she is heartened by efforts to reverse the trend. Last month during Earth Week, state, Tribal and local leaders from across the country gathered for a White House Water Summit. At the event, the Biden Administration announced a Freshwater Challenge, part of its America the Beautiful initiative to conserve and restore America's rivers, lakes, streams and wetlands.

"We're very excited that the U.S. government has taken such a leadership role in setting the specific target of restoration of rivers and other freshwater habitats. That's really going to be critical for time, for the populations of freshwater species to rebound," Thieme said.

Thieme added more than 100 inaugural members - including her organization - have signed on to support freshwater restoration in communities in seven states, with eight Native nations and 24 local governments.

After a devastating recent winter, the already-struggling mule deer population in Wyoming took a big hit and the state's wildlife agency is organizing to hear people's concerns.

According to the Wyoming Game and Fish Department, the state had an estimated 216,000 mule deer in 2023, a historic low and a 63% decrease from a high of 578,000 in 1991. It follows a pattern of decline across the West, due to extreme weather, habitat loss, disease and other factors.

Justin Binfet, deputy wildlife chief for the department, said some Wyoming herds were reduced by 80% due to the brutal winter ending in 2023.

"Everyone across the board is concerned over declining mule deer numbers," Binfet observed. "Whether that's landowners, outfitters, hunters, photographers, wildlife enthusiasts, conservationists, you name it."

The department will host nearly 40 community conversations across almost every game warden district in the state to hear Wyomingites' concerns about the iconic species.

Binfet pointed out the conversations are opportunities to get feedback outside regular surveys and a great way for constituents to meet their local wardens, managers and biologists. He noted the meetings are not leading to any scheduled changes in mule deer management but he expects common themes to emerge, which will be considered in future decision-making.

"The truth is we actually will hear the whole gamut of suggestions," Binfet acknowledged. "It'll just be one more piece of the puzzle to inform future management decisions."

Tomorrow ends the regular hunting season in many Wyoming hunt areas although most windows for mule deer closed earlier in the season.

Monarch butterflies could be on the federal Endangered Species list by year's end.

Eastern monarchs found in New York and other northeastern states saw an 80% population decline between the 1980s and 2020. Their Western counterparts have seen a 90% population drop. Environmental groups petitioned for them to be listed as "threatened" back in 2014 and the monarch became a candidate species in 2020.

Rebeca Quiñonez-Piñón, monarch recovery strategist and climate resilient habitat director for the National Wildlife Federation, said monarch butterflies face many threats.

"The main threats that we have identified for the monarch butterfly are habitat loss and fragmentation of the remaining habitats," Quiñonez-Piñón outlined. "Climate change is at the top of the list, definitely, and the excessive use of pesticides."

She called monarch butterflies a "canary in the coal mine" for pollinators and the ecosystem, a warning more needs to be done to help the environment. A dozen species of bumblebees are also candidates under the Endangered Species Act. They also fall victim to the same threats of monarch butterflies.

Home gardeners can play a role in helping monarch butterfly populations, by planting milkweed and goldenrod, which are helpful to the species. Milkweed is the only plant on which monarch butterfly caterpillars can eat and survive.

Mary Phillips, head of native plant habitat strategy for the federation, said there are some mistakes people make in trying to help monarchs thrive.

"Don't worry if, you know, you see the various predators," Phillips advised. "There's also a milkweed bug that sometimes goes on these plants. People get nervous about that. It's OK, it's natural, it'll go away. It will not harm the milkweed overall."

She added another common mistake is spraying garden or systemic pesticides which can harm monarchs. Some states are taking action to end the use of certain pesticides harmful to bees, butterflies and other pollinators. New York passed a law banning some uses of neonicotinoids because of their harmful effects on pollinators and other species.

A federal court in Montana has held a hearing more than two years after a coalition of environmental advocates sued the U.S. Forest Service and the Fish and Wildlife Service over expanding cattle grazing in the Paradise Valley, part of the Custer Gallatin National Forest.

The coalition, which includes Alliance for the Wild Rockies and the Western Watersheds Project, sued the agencies for extending the cattle grazing season by a month on nearly 1,400 acres of forest land.

Mike Garrity, executive director of the Alliance for the Wild Rockies, said the plan will mean more interactions between young, unattended cattle and grizzly bears, which would not end well for either one.

"Putting calves out a month early when they're very small just provides a 'fast food snack' for a grizzly bear," Garrity pointed out. "A small calf makes an easy target for a grizzly bear. They can't defend themselves. They're not very big."

Garrity noted ranchers then complain about bear activity to the Fish and Wildlife Service, which traps and kills the grizzlies. The Forest Service said the new policy does not increase grazing because it is counted by plots of land rather than acreage.

Garrity pointed out groups are working to restore the grizzly bear, which is currently listed as threatened under the Endangered Species Act. He added the Forest Service is not doing its part to help achieve balance.

"There's about a thousand grizzly bears in the greater Yellowstone ecosystem," Garrity reported. "There's hundreds of thousand of cattle. We don't have a shortage of cattle in this country but grizzly bears are threatened with extinction."

The federal judge could overturn the new grazing rules or order a complete environmental review.
