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.

Final federal plans for Greater sage grouse habitat in Wyoming and other western states were met with criticism last month but some said the overdue plans need to be passed.

The final Environmental Impact Statement from the U.S. Department of the Interior revises policies on nearly half of sage grouse habitat across 10 states. Some environmental advocates said the plans are not protective enough for the birds, whose populations have declined about 80% across their range since the mid-1960s.

Alison Holloran, executive director of the Audubon Rockies regional office of the National Audubon Society, said work needs to be able to happen on the ground now.

"We have wasted 10 years," Holloran contended. "We have serious issues with climate and drought, and invasive species, wildfire eating up our sagebrush. These plans have an ability to put our words into action, finally."

Current management is based on Obama-era 2015 plans, which the first Trump administration attempted to replace in 2019 in favor of its energy dominance agenda. Holloran acknowledged no one is sure what Trump's second term could mean for the new plans. The protest period ends Dec. 16.

Wyoming Gov. Mark Gordon wrote in a statement the federal plans "reflect extreme indifference to the primacy vested in Wyoming's exclusive authority" to manage the bird's population and he is "hopeful" about Trump's next term.

Holloran pointed out the Bureau of Land Management used the newest science, which has advanced since the 2015 plans, and the agency is charged with balancing different kinds of land use.

"I would say they are fair plans in taking what BLM lands are, as multiple-use," Holloran noted. "It is about how we all use our public land. And I think the American people need to understand that as well."

The final impact statement reduces the acres of "critical concern" from its last proposed plans by nearly 25% to about 630,000 acres but it also suggests tightening restrictions in those areas for oil, gas, wind and solar energy development.

Pronghorn, which can reach speeds of 60 miles per hour, are the second-fastest mammal on earth but their speed is no match for cars and trucks.

Colorado Parks and Wildlife recently released video showing more than 100 pronghorn killed along eastern Colorado roads after heavy snowfall blocked their escape routes.

Liz Rose, Colorado field representative for the Theodore Roosevelt Conservation Partnership, said unfortunately, such numbers are not unusual. Every year, 4,000 wildlife-vehicle collisions are reported across the state.

"Those are just the reported incidents," Rose pointed out. "The actual collision rate is thought to be more than 14,000 wildlife-vehicle collisions each year in Colorado."

Colorado is home to herds of bighorn sheep, deer, elk and pronghorn, and all must travel between winter and summer habitat for food and shelter. Rose emphasized because migration corridors intersect with roads and highways, motorists need to be on the alert. Each year, collisions cost $80 million in property damage and medical-related expenses, and 24 million in lost wildlife.

Wildlife-related recreation added $7.5 billion to Colorado's economy each year. Rose believes it is important for lawmakers to protect the revenue stream by creating and maintaining overpasses, underpasses, fencing and signage. The first major wildlife crossing on the I-70 mountain corridor, completed last June west of Denver, cost just over $10 million.

"Additional funding for the crossing infrastructure is desperately needed," Rose contended. "Because these are big projects and for them to be really successful, it's important to incorporate the best data, the best construction practices, to do it right."

Using GPS tracking data, scientists have identified 88 top-priority sites across the state where large herds routinely encounter roads and highways. Rose stressed everyone wants to feel safe driving across Colorado's iconic landscapes and most want to see wildlife, just not on the road.

"The risk of wildlife-vehicle collisions affects all of us in Colorado," Rose added. "Anyone who drives, especially near sunrise or sunset, we are all at risk of potentially encountering wildlife."

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.
