Long-term, standardized data collection for Michigan fisheries
Sport Fish Restoration funding has supported Michigan Department of Natural Resources (DNR) to develop a standardized sampling plan for long-term collection of spatial and temporal data for aquatic communities and habitat, which can supplement lake and stream classification data. This will allow for improved definitions of population status, identify spatial and temporal patterns in aquatic communities, and track changes due to landscape features, habitat characteristics, or regional factors such as climate. The sampling techniques identified are more intensive and extensive than traditional lake and stream surveys. The primary modules for sampling lakes in this sampling plan include fish surveys, limnology, zooplankton, and residential lakeshore development, while the primary modules for sampling streams are fish, water temperature, instream habitat, and riparian surveys. Fisheries managers have applauded Michigan's standardization of gear and sampling techniques, to get a more comprehensive data for the long-term.
