Rare W.Va. mussels may get species protection
By _Staff reports_ (mailto:) , The Charleston Gazette, November 2, 2010
CHARLESTON, W.Va. -- The U.S. Fish and Wildlife Service has proposed
Endangered Species Act protection for two rare freshwater mussel species known
to exist in streams in West Virginia and several other eastern states.
The rayed bean mussel is known to exist in only six states and one Canadian
province, while populations of the snuffbox mussel are found in 14 states
and one province.
Rayed bean mussels were believed to have disappeared from West Virginia
during the 1990s, but 600 of the rare shellfish were reintroduced in the Elk
River in 2006 and 2007.
Populations of the snuffbox mussel have been found in the Elk River, North
Fork of Hughes River near North Bend State Park, Middle Island Creek near
Wheeling and in Dunkard Creek in Monongalia County prior to last September's
massive fish kill in that stream.
The snuffbox is a thick-shelled, triangular shaped mussel with a yellowish
shell with dark green rays. The snuffbox is about 2 inches long when
mature, while the rayed bean is about 1.5 inches long and has a greenish shell
with heavy, wavy rays.
According to the Fish and Wildlife Service, nearly 70 percent of all U.S.
freshwater mussel species are already extinct or vulnerable to extinction.
Six mussel species known to live in West Virginia have already received
Endangered Species Act protection.
According to the Fish and Wildlife Service, the rayed bean mussel have been
eliminated from 75 percent of its historical range, while the snuffbox has
experienced a 65 percent drop in the number of streams in which it lives.
Dam and lock chamber construction, sand and gravel mining and pollution are
among causes attributed to the mussels' decline.
A public hearing will be held on whether or not to grant Endangered Species
Act protection to the two mussel species prior to any final decision by
the U.S. Fish and Wildlife Service
