Joy Grissom and Gerry Moll: Preserving East Tennessee’s natural heritage with shovels and wheelbarrows

If there’s a massive ecological disturbance in your neighborhood, who you gonna call?

The Knoxville Native Plant Rescue Squad, of course. 

Joy Grissom and Gerry Moll spent the past six years identifying, digging, hauling and muscling native East Tennessee plants to salvation from construction, grading and logging sites.

The duo has saved thousands of plants and their communities from certain demise. They have plucked plants to safety from areas ranging from a 170-acre logging operation in Cocke County to relatively small commercial developments in Knox County.

ORNL researchers receive 2021 Sustainability Science Award for mapping human influence on U.S. river and stream changes 

Researchers from Oak Ridge National Laboratory mapped and quantified hydrological changes throughout the country due to urban development, energy production and other human factors and won a prestigious award for their efforts.

The team’s analysis was published in the Proceedings of the National Academy of Sciences and received the 2021 Sustainability Science Award from the Ecological Society of America.

“The Sustainability Science Award recognizes the authors of a scholarly work that make a substantial contribution to the emerging science of ecosystem and regional sustainability through the integration of ecological and social sciences. The researchers will be recognized during the society’s annual meeting in August,” according to an ORNL release announcing the award.

The research coupled U.S. Geological Survey stream-flow records with geospatial modeling to quantify human impact on national water resources and concluded the 7 percent of affected aquatic systems hold 60 percent of North American freshwater fish, mussels and other species.

“This work exemplifies how ORNL’s interdisciplinary research in environmental and geospatial science helps equip decision makers with the tools needed to move our nation toward a more sustainable future,” Stan Wullschleger, associate laboratory director for ORNL’s Biological and Environmental Systems Science Directorate, said in the release.

Lead author Ryan McManamay, an aquatic ecologist and faculty member at Baylor University, was with ORNL’s Environmental Sciences Division at the time of publication. Co-authors include ORNL’s Sujithkumar Surendran Nair, Christopher DeRolph, the late April Morton, Robert Stewart, Matthew Troia and Budhendra Bhaduri; Northern Arizona University’s Benjamin Ruddell; and the University of Tennessee’s Liem Tran and Hyun Kim.

“It was a privilege to work with this team that spanned across multiple disciplines and institutions,” said Bhaduri, an ORNL Corporate Research Fellow and director of ORNL’s Geospatial Science and Human Security Division. “Given the impacts of climate change, there has never been a more pressing opportunity to address environmental sustainability. It’s a tremendous honor to make this scientific contribution and to be recognized for it.”

Integrating economics and ecology for seasonal migratory species conservation

Dr. Charles Sims
Howard H. Baker Jr Center for Public Policy

Baker Cafe Zoom Meeting - Free and open to the public

The Baker Cafe Series is an informal discussion about various topics. Guests are encouraged to ask questions that pertain to the topic and gain insight straight from the experts.

Species that migrate face different natural and anthropogenic threats than other species. Protecting migratory species poses unique policy challenges because survival depends on the migratory process's integrity through space and time.
