8am Breakfast and check-in

8:45am Welcome

9am “Prairie Ecosystems as a Model for Plant Biodiversity in the Home Garden”
Speaker: Lara Souza, Norman, Oklahoma

Learn about prairie diversity, plant traits, and their role in promoting system function as Dr. Lara Souza shares research she has conducted across Oklahoma’s native prairie ecosystems. Plant biodiversity supports pollinators, prevents soil erosion, and is one of the largest contributors to ecosystem function in both our prairies and our gardens. Because much of our world’s carbon is captured from our grasslands, its loss in biodiversity is a driving force in the future of our climate. By modeling these ecosystems in our home gardens, we can grow sustainable and beautiful pockets of life.
