Spotlight on Daniel Kowalski: The Mussel Behind Aquatic Ecosystem Protection

Mussel Surveying Season in Michigan

As summer approaches, so does freshwater mussel surveying season in Michigan. Typically conducted between June 1 and October 15, these surveys help evaluate and salvage a vital natural resource before in-water construction or development activities begin. Freshwater mussels (Order: Unionoida) have been identified as the most imperiled of any major group of animals in North America. Of the 43 species found in Michigan, 19 (43%) are state threatened or endangered and five species are federally threatened or endangered. Because many freshwater mussel species are protected, proper evaluation and survey helps projects stay compliant with environmental regulations while protecting sensitive aquatic ecosystems.

Meet Daniel Kowalski

Meet Daniel Kowalski, Ecological Project Manager and Staff Malacologist at ASTI Environmental and one of the region’s experienced native freshwater mussel specialists. With more than 16 years of experience in aquatic ecology and wetland systems, Daniel focuses on ecological assessments of aquatic biota, including native freshwater mussels and fish populations throughout the Great Lakes region.

Daniel’s work includes wetland and critical habitat delineations, threatened and endangered species assessments, and implementing state and federal ecological survey protocols across the United States. He also has experience supporting ecological risk assessments, restoration oversight, spill response, and Natural Resource Damage Assessment, helping clients navigate complex environmental requirements while supporting responsible development.

Supporting Projects Across Michigan Waterways

Daniel has conducted freshwater mussel surveys at over 100 locations on nearly 70 waterbodies across the Great Lakes region, including the following in 2025: The Kalamazoo River in Calhoun County, the Looking Glass River in Ionia County, the River Raisin in Washtenaw County, the Flint River in Genesee County, the Pine River in Gratiot County, the Middle Rouge River in Wayne County, and Stoney Creek in Macomb County. These efforts help ensure natural community impacts are minimized whilst construction or development activities remain compliant.

Experience and Certifications

Daniel is both a Michigan Certified Mussel Surveyor and an Ohio Approved Mussel Surveyor and holds technical training including NAUI SCUBA Open Water Diver certification with full face mask (FFM), Swift Water Diver certification, Stormwater Management Operator certification for streams, and OSHA 40-hour HAZWOPER.. He is also an active member of the Society of Wetland Scientists, the American Fisheries Society, and the Michigan Wetlands Association.

Planning an In-Water Project?

If your project involves impact below the ordinary high-water mark (OHWM) or work near aquatic habitats, early coordination with experienced industry professionals is essential.
