CHATTANOOGA, Tenn. – Tennessee and the rest of the Southeast are home to thousands of aquatic species, many of which are unique to the region.

After more than a year of research, the Tennessee Aquarium Conservation Institute and the University of Georgia River Basin Center released a survey of more than 1,000 fish, crayfish and mussel species.

Anna George, the institute’s director, says scientists discovered that more than 90 percent of all American mussel and crayfish species live within a 500 mile radius of Chattanooga.

"The amazing thing about the Southeast is we have all of these animals living right here in our backyard, but because they're beneath the surface of the water we don't often get chances to see them unless you're visiting the aquarium,” she states. “But what's really great about this project is that we can raise all of that information to the surface."

Researchers also found that the long-term care and survival of waterways are crucial to the health and future of the wildlife.

Additionally, federal and state funding to support aquatic species in this study was lower compared with others found in the rest of the country.

George adds that researchers hope their survey will serve as a master plan to guide research and conservation work.

George says she also hopes the collection of information on the marine life will provide a framework for policy makers and conservation groups to move forward.

"We can look at where our animals are found, and really have a national conversation about, 'Hey, we have an underwater rainforest here in the Southeast,” she points out. “We have so much to protect,' and now we have the guidance on where to spend our time protecting it."

In Tennessee, the sub-basins of Pickwick Lake, Wheeler and Upper Clinch were listed among the highest priority watersheds in the survey. Priority was ranked based on the number of endangered or threatened species and the number of species overall.

The State of Washington is proposing to downgrade gray wolves from "endangered" to "sensitive" status as a species.

At last count, there were 260 gray wolves in Washington, a population which has steadily grown at an average rate of 23% since 2008, according to the Department of Fish and Wildlife.

Colin Reynolds, senior adviser for the Northwest program at Defenders of Wildlife, contended changing the gray wolf status could jeopardize the progress. He said in the western two-thirds of the state, gray wolves are protected under the federal Endangered Species Act but in the eastern third, there are no federal protections and wolves are managed by the state.

"Right now in the eastern third of Washington, there are penalties for the illegal killing of gray wolves, and there's also penalties ascribed to that," Reynolds explained. "If the classification goes from 'endangered' to 'sensitive,' as the Washington Department of Fish and Wildlife would like, those penalties are a little bit less, in a number of circumstances."

Reynolds pointed out the gray wolf recovery efforts are guided by the state's Wolf Conservation and Management Plan, adopted in 2011. Since then, wolves have met recovery standards in certain parts of the state but not all, so he argued it is no time to change the rules.

The state countered reclassification is warranted, as gray wolves have seen 15 years of consecutive population growth, data models project it is likely to continue and there are enough state-level protections already in place to keep the population sustainable. Reynolds disagreed.

"We totally recognize and celebrate that the population has grown," Reynolds acknowledged. "But a population growth isn't the same as the recovery standards in the Wolf Plan. We haven't met that geographical distribution."

Reynolds also noted recent instances of gray wolf killings across the West. The deaths of three gray wolves in Oregon prompted the U.S. Fish and Wildlife Service to issue a $50,000 reward for information about the case.

Conservation groups say the Hawaiian Islands are on the leading edge of the fight to preserve endangered birds, since climate change and habitat loss are making it difficult for many indigenous species to survive.

A coalition of conservation organizations will hold the annual Manu o Ku Festival this weekend to celebrate the islands' myriad species.

John Kantor, a wildlife biologist with the National Wildlife Federation, said the U.S. Migratory Bird Treaty Act has helped preserve many exotic Hawaiian species.

"The federal Endangered Species Act, and the funds that are raised for migratory birds under the various programs there, are funding the frontline researchers and conservationists and folks that are trying to solve this multitude of issues that threaten Hawaii's birds," he explained.

The festival, sponsored by the Conservation Council for Hawaii and the National Wildlife Federation, will run from 10 a.m. to 2 p.m. Saturday at the Coronation Pavilion of the Iolani Palace in Honolulu.

Kanter said the Migratory Bird Treaty was created in 1918 and updated in 1936. In conjunction with Canada, Mexico and other nations, it limits the taking of certain species for commercial products or as game. He cited the wood duck as one example, which is now plentiful but was almost wiped out a century ago.

"That species was almost extinct," he said, "and it is a hunted species - but there's strict regulations that are developed between the U.S. Fish and Wildlife Service and the states every year, based on the number of birds, that then are applied to the following season."

This year's festival celebrates the manu o ku, or white fairy tern, as an ambassador for other native Hawaiian species. Organizers have said conservation groups, educators and others are invited to share games and activities for people of all ages in learning about the manu o ku.

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.
