Our Underwater Experience Facilitates Accurate Freshwater Mussel Density Estimates
Native freshwater mussels are an important part of river ecosystems because they remove particulate matter from the water column and are excellent indicators of water quality. Today, many bridge and road rehabilitation projects require freshwater mussel surveys as specified by the Federal Endangered Species Act. These projects typically involve:
- Mussel habitat delineations
- Qualitative surveys to determine presence or absence
- Quantitative surveys to determine mussel diversity and density
- Mussel translocations and subsequent monitoring programs
