  • MBS specializes in field surveys (fish, mussels, amphibians and macroinvertebrates), laboratory processing and taxonomic identification of macroinvertebrates collected with current protocols from all regions in North America. 
  • MBS has one of the most respected taxonomists in the western region, trained & certified to work on USGS NAWQA samples in the mid-1990’s, he has processed and identified 1000's of samples from ID, WY and MT DEQ's, BLM, MTFWP, PIBO and EMAP.

Small Budget Projects

It's hard to get the big consulting firms to pay attention to your small projects < $5,000, the overhead makes these un-profitable. MBS is nimble in assembling a field crew or processing your samples with quick turn around times.   

MBS can tackle projects on small travel budgets and is not afraid of getting dirty, even preferring camping to hotels, to keep our project costs lower than big consulting firms. 

Technical Support

​Additional Field Associates include fisheries scientists with M.S. and Ph.D's from Montana State University, a B.S. from UC Santa Barbara and multiple macroinvertebrate processors with B.S. in Environmental Studies from Carroll, the Univ. of Montana and MSU.
