Daguna Consulting, LLC provides scientific expertise on the conservation and management of endangered species inhabiting our freshwater ecosystems.

This summer, we relocated mussels from under the Ford Bridge in St. Paul, Minnesota prior to repairs and bank stabilization at the site.  We found a remarkable assemblage comprising 17 species and nearly 400 indiviuals in only a tenth of an acre!

In recent years, our work has focused on better understanding the status and population dynamics of the federally endangered James spinymussel (Pleurobema collina).  We have been partnering with the Virginia Department of Game and Inland Fisheries, Three Oaks Engineering, James Madison University, Virginia Department of Conservation, and  the U. S. Geological Survey in Virginia.  

In 2016, we completed conservation plans for several state-listed mussels inhabiting the Virginia portion of the Upper Tennessee River Basin.  Our work will guide informed management of an increasing imperiled fauna. 

Current, ongoing projects in 2017:

  1. Surveys for Dwarf Wedgemussel in eastern Virginia Streams
  2. Relocation of mussels away from construction impacts in a mountain tributary to the Holston River in Virginia, in a prairie stream in western Minnesota, and in the St. Croix River on the border of Minnesota and Wisconsin
  3. Occupancy study of federally listed speices in Copper Creek for the Virginia Department of Game and Inland Fisheries
  4. Relocation of mussel fauna in the Mississippi River (Ramsey County, Minnesota)
  5. Mussel survey and relocation at Petttibone Condos on the Wisconsin side of the Mississippi River
  6. Monitoring relocated mussels using Passive Integrated Transponder (PIT) tags and employing mark-recapture models to estimate survival
  7. Cooperating with James Madison University to better understand population dynamics and detection of the federally endangered James spinymussel 
  8. Population monitoring of the federally endangered James spinymussel using mark-recapture methods and Progam Mark models
