Although it has experienced a decline, the Service found that the purple lilliput has not yet met the threshold for ESA protection.
InIsaac Lea described the longsolid Fusconaia subrotundaa medium-sized mussel up to 5 inches long, which can live up to 50 years. It is found in small streams to large rivers, including the Ohio River, and prefers a mixture of sand, gravel, and cobble stream bottoms. With a historical high of known populations, 60 are known to exist today, and 48 of those are small populations in poor condition.
The round hickorynut Obovaria subrotunda is a small- to medium-sized mussel up to 3 inches long, which lives up to 15 years.
It is found in small streams to large rivers, and prefers a mixture of sand, gravel, and cobble stream bottoms. With a historical high of known populations, 65 are currently known to exist today, and 45 of those are in poor condition.
Purple lilliput Toxolasma lividum is a small freshwater mussel, up to 1. It is found in small streams to large rivers, Hickory flirting search the Tennessee River, and prefers a mixture of sand, gravel, and cobble substrates. Historically there were known populations, with remaining today, and of those, 87 are small populations, confined to a limited area, with no evidence of young mussels or mussels of multiple ages, as you would expect in healthy populations.
These mussels have suffered impacts from negative influences commonly found in central and eastern U. Beyond the overall of populations, the purple lilliput is still found in in all six major river basins where it is historically known to occur. Beyond looking at historical declines, biologists also assessed a variety of scenarios to get an idea of future trends, and the purple lilliput is likely to maintain more than populations across all six river basins where it occurs.

The purple lilliput does not currently meet the threshold of endangered — in danger of going extinct throughout all or a ificant portion of its range, or threatened — and neither is it likely to become endangered in the foreseeable future throughout all or a ificant portion of its range.
Federally funded or authorized projects would be reviewed for impacts to the listed mussels, and actions of the federal government may not jeopardize their existence. Listing would prohibit harassing, harming, pursuing, hunting, shooting, wounding, killing, trapping, capturing the listed mussels and attempts to engage in such activity, except where permitted or in certain cases where it is part of a broader effort to conserve the mussels.
The listing would make recovery efforts for the mussels eligible for funding under the ESA. When the Service proposes an animal or plant for listing as endangered or threatened under the ESA, we identify specific geographic areas called critical habitat that are essential to conserving those species. Along with the proposal to list the longsolid and round hickorynut, the Service also proposes deating critical habitat, or habitat critical to the recovery of the species.
Deation of critical habitat does not affect land ownership, does not allow the government to take or manage private property, nor does it establish a refuge, reserve, preserve or other conservation area, and it does not allow government or public access to private land.
Deating critical habitat on private land has no impact on landowner activities that do not require federal funding or federal permits. Critical habitat alerts federal agencies that they are required to make special conservation efforts when they work, fund or permit activities, including consulting with the Fish and Wildlife Service on the effects of their actions. The proposed critical habitat for the longsolid is comprised of 12 units, along a total 1, river miles, in Alabama, Kentucky, Pennsylvania, Tennessee, Virginia, and West Virginia.
Proposed critical habitat for round hickorynut is comprised of 14 units along a total of river miles in Alabama, Indiana, Kentucky, Mississippi, Ohio, Pennsylvania, Tennessee, West Virginia.
Eight of the proposed units overlap in part or whole. All proposed units are occupied by the species, and all are considered essential to the conservation of the longsolid or round hickorynut mussels because they provide the suitable habitat necessary for this species to survive and reproduce.
The Service compiled and analyzed data for these wide-ranging species. These status assessments subsequently went through a peer-review process. For each of these species, this represents the first time such a comprehensive, range-wide investigation into their status has been conducted. After examining historical, current, and projected future populations in light of the threats facing these mussels, the Service found that while all three have declined over time, only two, the longsolid and round hickorynut, currently warrant the protection of the ESA, something afforded our most imperiled species.
According to these rules, certain actions with a minimal level of disturbance and no anticipated long-term negative impacts to the species would be excepted from prohibitions.
Those actions are species restoration efforts by the Service or state wildlife agencies, and stream channel and bank restoration projects for creation of natural, physically stable, ecologically functioning streams, taking into consideration connectivity with floodplain and groundwater aquifers.

We will post all comments on regulations. Although people are far more familiar with saltwater mussels commonly offered in restaurants, the United States is home to a tremendous diversity of freshwater mussels. There are more than species worldwide, with North America being a global center of mussel diversity, with about species.
Sensitive to pollution, native mussels are indicators of broader stream health — vibrant mussel populations typically reflect a healthy stream. In addition to being indicators of stream health, mussels clean water as they feed, filtering their food from the water column, and with it, sediment and other pollutants.

Endangered species act decisions for longsolid, round hickorynut and purple lilliput mussels
What protections would these mussels receive by being on the threatened and endangered species list? What is critical habitat? How much critical habitat is being considered for the longsolid and round hickorynut?
How did the Service come to this conclusion? Is the Service proposing a 4 d rule as the ESA allows? How do I provide comments on the proposed listing, 4 d rules, and critical habitat? Why should we care about mussels?
