Interview with Dwayne Estes. Mr. Estes serves as executive director for SGI. For ten years Dwayne has served as Professor of Biology at APSU and was promoted to Full Professor in 2015. Grassland loss is the single greatest conservation issue currently facing eastern North American biodiversity. Southern grasslands are nearly extinct and the species that depend on them are fading fast. The Southeastern Grasslands Initiative (SGI) is a collaboration of leaders in international biodiversity conservation led by the Austin Peay State University Center of Excellence for Field Biology, in partnership with the Botanical Research Institute of Texas, North Carolina Botanical Garden, and Roundstone Native Seed. SGI seeks to integrate research, consultation, and education, along with the administration of grants, to create innovative solutions to address the multitude of complex issues facing Southeastern grasslands, the most imperiled ecosystems in eastern North America.
