Wetland Biologist
Cuyahoga Valley NP, 330-342-0764 ext.7
Sonia Bingham is a duty stationed employee at Cuyahoga Valley National Park, where she manages the Wetland Monitoring Program and Invasive Plant Monitoring at CUVA. Prior to joining the network in 2007, Sonia was an environmental consultant, where she gained extensive professional field experience assessing and monitoring wetlands and streams in Northern Ohio and other locations throughout the Midwestern U.S. In this work, she conducted wetland delineations, developed restoration plans, and surveyed plant, fish, macroinvertebrate, and freshwater mussel communities. Sonia received a B.A. in Biology from Hiram College, Ohio and an M.S. in Environmental Science from The Ohio State University. Her research focused on root habitat for aquatic macroinvertebrates created by common forest trees at the stream bank.
Aquatics Ecologist
Missouri State University
Cameron joined the Heartland I&M Network's aquatics program as an ecologist in 2024. He primarily assists with data analysis, report writing, field surveys, sample identifications, and maintaining reference collections for the network's fish, aquatic invertebrate, and aquatic plant monitoring projects. Cameron graduated from the University of Arkansas, Fayetteville with a B.S. in Biology in 2015 where he described a new species of freshwater mite endemic to the Ouachita Mountains, Torrenticola larvata. In 2017, he started an SCA internship at Buffalo National River assisting park ecologists with various monitoring and outreach programs. The following year, Cameron started graduate school at Missouri State University where he studied the effects of riparian vegetation structure on dragonfly and damselfly communities inhabiting Ozark spring streams. He received his M.S. in Biology in 2020 before joining the Heartland I&M Network as a research specialist. Cameron is a naturalist with a keen interest in how aquatic invertebrate and plant communities are responding to environmental changes.

Doug Marcum
Biological Science Technician
Cuyahoga Valley NP, 330-342-0764 ext. 3Doug has been working as a seasonal biotech under Sonia Bingham since 2011. While initially hired to assist with the wetlands monitoring program, he has been fortunate enough to contribute in other ways as well. Doug leads a breeding bird study at Cuyahoga Valley National Park (CUVA), while occasionally assisting with other wildlife studies. His BS in Conservation Biology and MS in Ecology both come from Kent State University. Doug’s master’s research (at CUVA) examined the effects of habitat and succession on mammal communities at two spatial scales.
