Matt Ashton

Matt is a native of Cleveland, Ohio, but has lived in Maryland for approximately three years since joining the Department of Natural Resources. His professional interests are freshwater mollusk and darter ecology, imperiled species, large river aquatic communities, and the ecological role freshwater mussels have in Maryland streams. When free, Matt likes to work in his vegetable garden, snorkel and SCUBA dive, fish, and enjoy the outdoors.

Matt has been working on the DNR’s Maryland Biological Stream Survey since 2007, with his effort primarily focused on using the statewide stream assessment to describe the environmental conditions that influence freshwater mussel distribution. He works with other DNR biologists studying the distribution, ecology, and stressors of stream fishes and crayfish, and recently completed a two year assessment of Maryland’s large rivers as part of the National Rivers and Streams Assessment. Matt also has been instrumental in bringing together information on the status of the Chesapeake logperch (Percina bimaculata) and non-native Oriental weatherloach (Misgurnus anguillacaudatus).

Matt received his B.A. in Biology from Hiram College, where he did field and laboratory work on native fishes, animal husbandry, and developing inquiry based science curricula. He received his M.S. in Biology from Tennessee Technological University after characterizing the current distribution, status, and microhabitat of the federally threatened snail darter (Percina tanasi).
