Surveying for dwarf wedgemussels

Detailed Description

Understanding ecological flow needs requires an evaluation of species distribution and field habitat conditions.  USGS researchers conduct various types of surveys to locate new populations, monitor existing populations, and quantify habitat.  Here, researchers are conducting quantitative quadrat surveys for freshwater mussels to estimate the number of individuals that are found both above and buried below the stream bottom.
