JACKSON, Wyo. – A coalition of conservation groups wants the U.S. Fish and Wildlife Service to phase out wintertime efforts to feed the elk at the Jackson Hole National Elk Refuge.

The groups are concerned that elk feeding in large groups could worsen the spread of lethal chronic wasting disease, which was recently detected for the first time in the region but not yet in the refuge.

Timothy Preso, an attorney with Earthjustice, says the feeding program makes it more likely that the malady will spread.

"Chronic wasting disease is transmitted by these abnormal proteins that get into the soil and into the vegetation,” he explains. “And there's really no known means to eradicate them, so that literally, the refuge would become a disease infection zone for elk that come back to graze."

Earthjustice – along with Defenders of Wildlife, the National Wildlife Refuge Association and the Sierra Club – sent a letter this week to the Fish and Wildlife Service, urging the agency to phase out the winter feeding plan and let the elk forage in their natural habitat.

Preso says such a plan was developed by the agency in 2008 but has been held up for a decade due to wrangling between federal and Wyoming officials.

Preso explains chronic wasting is similar to mad cow disease in cattle and is always fatal.

He adds the situation in the elk refuge is on the verge of becoming critical.

"With the time that earlier debate played out, chronic wasting disease was a few counties away,” he states. “Now, it's on the doorstep.

“And we let a decade slip by with no progress, which is very unfortunate because now, the consequences of that delay are becoming much more clear."

Preso says Fish and Wildlife did not feed the elk during last year's mild winter, and the herd survived without a major problem.

He says his group is sounding the alarm in hopes the agency will respond to this year's request without being taken to court.

"We haven't taken any additional legal action, because we wanted to come back to the Service and see if they will take a responsible initiative in this moment to address this issue before we have a wildlife disease disaster on the elk refuge," he states.

Preso says the winter feedings would need to be phased out over time, so the refuge's 8,000 elk can re-adopt their natural foraging behaviors.

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.

Today is Earth Day, and one initiative in southern Arizona is helping build public gardens providing beneficial habitat for pollinators, from Monarch butterflies to bees and bats.

Emily Bishton, founder and coordinator of the Arivaca Pollinator Pathway Project, said the human population depends on these animals and insects, as many of our foods and plant-based products require pollination. But human activity and climate change have put pollinators in jeopardy and Bishton wants to increase awareness of how crucial they are.

"The best chance you have for attracting and nurturing pollinators is with the species that they've co-evolved with," Bishton explained. "They will instinctively know that is food for them, or a place they can lay their eggs. They also are more likely to be able to put up with the way our climate is now and the way it is changing."

Bishton pointed out one focus of the project is to get Arizonans to plant more native species like milkweed, which is especially critical for Monarch butterflies. She would also like people to reconsider the use of pesticides since they do kill pests but also other beneficial insects. She suggested contacting a local county extension service or master-gardener program for alternative methods.

Madian Romero, technical assistant supervisor for the Caviglia-Arivaca Library, has been responsible for getting teenagers in the area to participate in the Arivaca Pollinator Pathway Project. They not only help build garden spaces around town but grow their knowledge behind the importance of pollinators, as well as community building.

"The teens, they've come up with ideas on how to fundraise for the projects," Romero emphasized. "Each business that agrees to have a garden, it can be free."

Romero added the project has also been a character-building exercise for the young people of Arivaca, and hopes it is an experience they will cherish.

The state Department of Natural Resources and Iowa State University are looking for volunteers to help create a new Bumble Bee Atlas.

Bees are an important part of the ecosystem, and scientists are figuring out their habitats to help them thrive.

Iowa is home to at least 14 species of bumble bees that help pollinate native wildflowers and flowering crops in farm fields and backyard gardens.

Iowa State University University Professor of Sustainable Agriculture and plant pathologist Matt O'Neal said the U.S. Fish and Wildlife Service recently listed several bee species as endangered.

"And that includes the Rusty Patch bumble bee," said O'Neal, "20% of what it used to be, and that includes parts of Iowa. There is also evidence that other bumble species are in decline and so, this survey will give us a chance to see where those bees are and how abundant they are."

With that information, O'Neal said scientists can work to protect the bees' habitats and create Iowa's Bumble Bee Atlas.

It's part of a larger project to map the bees and foster bee development nationwide. Sign up online to volunteer.

The national project is part of a collaboration with the Xerces Society for Invertebrate Conservation.

Some 900 people have volunteered for the national atlas project, and counted more than 20,000 bumble bees - which O'Neal said face several major threats.

"Pesticide exposure, parasite and pathogens," said O'Neal, "and then the last 'P,' and probably the most important, is poor forage."

The researchers will work to alleviate those threats by knowing where the bees are.

Volunteers have discovered species thought to be gone from their states, contributed to new field guides, and improved scientists' understanding of bumble bee populations across the country.
