An environmental group is suing the U.S. Fish and Wildlife Service to protect the Arkansas mudalia snail under the Endangered Species Act.
In Arkansas and Missouri, including along the North Fork River, mudalia are critically endangered freshwater snails.
Trisha Sharma, legal fellow at the Center for Biological Diversity, emphasized the need to save the snail from vanishing entirely. She said freshwater mollusks are the most endangered group of animals in North America, and snails are the most endangered mollusks.
"We've already lost more than 70 species of freshwater snails," Sharma pointed out. "The Endangered Species Act has a very high success rate. So if we can get it listed and protected under the ESA, it's highly likely that the species will survive and be able to continue playing its important role in the ecosystems where it's found."
Sharma noted areas where the Arkansas mudalia can be found have decreased by 90% and the main threat to the species is habitat degradation, primarily from dam construction and operation along the rivers.
Sharma emphasized mudalia is also threatened by habitat loss from grazing, logging and mining. She added climate change is also expected to threaten the species.
"Part of what can make a species more resilient to climate impacts is its ability to disperse as its habitat becomes unsuitable, and to essentially relocate to areas where it can survive," Sharma explained. "But snails have a pretty narrow set of habitat requirements and very limited dispersal capabilities."
Sharma said freshwater snails play a crucial role in managing nutrients by consuming detritus and plant matter, preventing their decay and subsequent disruption of water quality, and snails are vital for food webs, converting unusable food sources into usable ones for birds and turtles.

With manatee season in full swing, Florida's gentle marine mammals gather in warm waters to escape winter's chill. But these iconic creatures face growing challenges from habitat loss, water pollution and boating collisions.
A new proposal from the U.S. Fish and Wildlife Service aims to address these threats by revising critical habitat protections for the first time in nearly 50 years.
The agency proposes protecting more than 1.9 million acres of critical habitat for Florida manatees and more than 78,000 acres for Antillean manatees in Puerto Rico, marking the first update since 1976.
"It's a long-overdue revision of looking at what is vital habitat for manatees to find warm water, to be able to feed, to travel, to give birth and safely raise their young," said Elizabeth Fleming, a senior Florida representative for the nonprofit Defenders of Wildlife.
Previously, critical habitat was designated based solely on areas where manatees were known to congregate. The proposed changes now incorporate scientific research, identifying areas based on the physical and biological features essential for their conservation.
The updated habitat proposal is open for public comment until Jan. 24.
Katherine Sayler, a southeast representative for Defenders of Wildlife, said the loss of warm-water habitat is a major threat to manatees, many of which now depend on power-plant outflows for warmth. The updated habitat proposal includes natural springs such as Manatee, Fanning and Silver Springs, which stay at 72 degrees year-round and are crucial for their winter survival.
"They need travel corridors to get between these areas of warm water," Sayler explained, "and that's where we think we need to really allow for the public to engage and really make comments on where are these travel corridors."
Seagrasses are vital to the health of marine ecosystems. For more than a decade, the Indian River Lagoon has experienced extensive seagrass meadow loss because of algae blooms associated with nutrient runoff and degraded water quality from septic overflow leaching into the environment.
Fleming added that the proposal is a first step. Still, much more must be done to address concerns, especially in an area known as Mosquito Lagoon, which she described as a critical habitat for manatees.
"This area of the Indian River lagoon that has had some regeneration of seagrass isn't included in the new manatee-critical habitat," she said. "So, we see that as a big omission."
Anyone can comment on the proposed habitat changes via mail or electronically on regulations.gov. Conservationists hope increased awareness during manatee season will strengthen safeguards for Florida's iconic marine mammal.

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."
