Savanna Ecosystem Restoration and Importance

Theresa Edwards, a ranger at Government Canyon State Natural Area, introduces the unique and endangered savanna ecosystems. She explains the threats they face, such as housing developments and cattle grazing, and highlights the historical role of fire in maintaining these ecosystems. Due to fire suppression, many savannas have transformed into woodlands. Restoration efforts at Government Canyon aim to reclaim these spaces by removing trees and promoting native grasses.
