Fisheries Applied Research and

Technical Assistance

Fishery biologists with Montana Ecological Services collaborate with biologists and scientists in other branches of the US Fish and Wildlife Service and with partners in other Federal and State agencies to coordinate, lead, and support applied research projects designed to give management biologists the information they need to make informed decisions about native fish conservation given threats like nonnative species, habitat fragmentation, and climate change.  Montana Ecological Services also provides technical assistance in` support of applied research projects such as decision support models.  Please click on the links below to see examples of projects in different field offices in Montana.
