Sasha Bozimowski is a Budget Analyst in Ann Arbor, MI.
Sasha has expertise using traditional methods of community assessment for multiple wetland species including aquatic benthic invertebrates, fish, and vegetation. She also uses advanced monitoring technologies (remote water quality monitoring and sample collection, hydroacoustic sonar and machine learning) to achieve a greater understanding of essential Great Lakes coastal wetland functions over diurnal, seasonal, and annual timescales.

Restoring Wetland Habitat and Function at the Shiawassee National Wildlife Refuge
Hydrologic connectivity is essential to maintaining coastal wetland services and functionality. Impounded wetlands often do not provide essential services such as flood mitigation and nutrient retention, nor can they be utilized as spawning and nursery habitat by important Great Lakes fishes. The Shiawassee National Wildlife Refuge manages hundreds of acres of historical coastal wetland habitat...
