URBANA (AP) — Scientists from the Illinois Natural History Survey are looking for sites along the Vermilion River in eastern Illinois to transplant endangered mussels from Pennsylvania.
Survey scientists last summer moved 1,200 northern riffleshell and clubshell mussels to locations on the Salt Fork and Middle Fork rivers in the area.
Jeremy Tiemann is with the Natural History Survey. He tells The News-Gazette in Champaign (http://bit.ly/10j4KQJ ) the moves are part of an effort backed by the Illinois Department of Natural Resources and the U.S. Fish and Wildlife Service to restore the two species to their historical range in Illinois.
The freshwater mussels are among the most endangered in North America. They're also considered a good indicator species for water quality.
The mussels moved to Illinois come from the Allegheny River.
