​Maryland Department of Natural Resources' (DNR) Maryland Biological Stream Survey (MBSS) is getting ready for another exciting year! In 2020, we will have one training session for our volunteer stream sampling program, Maryland Stream Waders.

Stream Waders volunteers will help to fill the gaps in areas of interest to the Maryland Biological Stream Survey crews in 2020. This year, your efforts will be supporting the MBSS by providing data on the effectiveness of various stream restoration projects.

Volunteers are trained and outfitted to collect benthic macroinvertebrate samples which are turned in to DNR biologists who subsample, identify, and rate the sites according to our Index of Biotic Integrity. Stream Waders is rigorous and produces data that are available to the public on the StreamHealth website.
