BLACK BUTTE MINE AQUATIC ASSESSMENTS (TINTINA RESOURCES)
MBS with our collaborators, Rhithron (Periphyton) and Peter Brown, Ph.D (Fish), will continue to collect and analyze baseline aquatic assessment data in 2017, as we did for their initial assessments in 2014-2016. See 2 year report: http://www.tintinaresources.com/ In addition to the aquatic communities previously evaluated, this year we collected rocky mountain sculpin for tissue analysis of baseline metals (Energy Laboratories) and performed redd counts in the fall. MBS's Aquatic Ecologist has provided scientifically-robust, biological data for other controversial projects, including Otter Creek Coal Tracts, Spring Creek/Big Metal Coal Mine Expansion, Absoluka Mine and Coal Bed Natural Gas monitoring in Wyoming and Montana (see Past Projects).
MISSOURI RIVER BASELINE MACROINVERTEBRATE STUDY, UPPER MISSOURI WATERSHED ALLIANCE (UMOWA)
UMOWA contracted with MBS's Aquatic Ecologist in 2015 to began the Missouri River Baseline Monitoring program and has continued this study in 2017, including a flushing flow component. This study was initiated to fill the need of establishing baseline monitoring stations, especially for benthic macroinvertebrates and water chemistry in the Blue Ribbon section of the Missouri River between Wolf Creek and Cascade. This study will allow us to document and understand the shifting insect communities, including explosions of scuds and isopods, decreased caddisfly hatches and missing cohorts of BWO mayflies. Braden Lewis of Headhunters (a serious bug guy) has been an integral collaborator on this project.

WESTERN PEARLSHELL MUSSEL POPULATION ASSESSMENT AND CONSERVATION ACTIONS IN WESTERN MT (MTFWP, MT Chapter AFS, MTNHP, Turner Enterprises)
MBS's Aquatic Ecologist has been tracking and reporting on mussel populations in MT since 2004. The western pearlshell mussel (WEPE), Margaritifera falcata has experienced significant statewide range reductions in the last 100 years and is now known from ~85 populations, of which, only ~20 are expected to be viable 100 years from now. Short-term trend analysis has shown significant losses of WEPE populations in the last decade (see figure). We have been investigating ways to stop the loss of this species of concern, including translocating of adult mussels, propagating juveniles from fish hosts with marginal success. (See reports: http://mtnhp.org/Reports.asp?key=1) and Pacific Standard News Article
