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

Wow!  That was some mussel population!  We just moved over 2,000 mussels beyond the direct impact of a bank restoration in a western Minnesota river.  We documented 13 species, including one state-listed species.  This relocation ensured these mussels can continue to thrive, while land managers take action to keep sediment out of the river.

In 2017, 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 individuals 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. 

 2018 projects:

  1. Preparing a Biological Assessement (BA) for a barge loading facility that may impact endangered species habitat in the Mississippi River
  2. Surveys for protected mussels in tributaries to the Ni River near a proposed residential development outside of Fredericksburg, Virginia
  3. Relocation of a mussel assemblage for a bridge replacement in southwest Virginia
  4. Relocation of a mussel assemblage in a western Minnesota river prior to a SWCD bank restoration project
  5. Survey and relocation of mussels in the James River at a dredge site
  6. Relocation of mussel fauna at an Army Corps of Engineers bank stabilization project near Lynchburg, VA
  7. Relocation of state-listed mussels from a marina along the Minnesota bank of the St. Croix River prior to dock removal and replacement
  8. Occupancy study of federally listed speices in Copper Creek for the Virginia Department of Game and Inland Fisheries
  9. Mussel survey at a proposed barge mooring facility on the Wisconsin bank of the Mississippi River
  10. Quantitative sampling at long-term monitoring sites in the Clinch River for the U. S. Fish and Wildlife Service
  11. Survey for mussels in the Upper Iowa River prior to bridge replacement
  12. Providing technical assistance to a mittigation bank enhancing endangered species habitat in northern Virginia

  5. Relocation of mussel fauna in the Mississippi River (Ramsey County, Minnesota)
  6. Mussel survey and relocation at Petttibone Condos on the Wisconsin side of the Mississippi River
  7. Monitoring relocated mussels using Passive Integrated Transponder (PIT) tags and employing mark-recapture models to estimate survival
  8. Cooperating with James Madison University to better understand population dynamics and detection of the federally endangered James spinymussel 
  9. Population monitoring of the federally endangered James spinymussel using mark-recapture methods and Progam Mark models
