INHS researcher Jeremy Tiemann is part of a team working to relocate endangered mussels from a bridge construction site in Pennsylvania to Illinois rivers. The first mussels (relocated in 2010) were given PIT (Passive Integrated Transponder) tags to allow monitoring and after a year and a half, approximately 80% of the relocated mussels had survived. An additional 1200 were transplanted in 2012, and now, new locations are being sought for additional transplants.
