Student Research at Leon Creek and Salado Creek Greenways in San Antonio, Texas
May–August 2024
EcoJEDI students measured forest structure and composition in Leon Creek Greenway. Data for soils, ground cover, shrubs, and trees were collected from multiple plots across the greenway to evaluate differences among upper, mid-slopes, and the dry creek bed from the east to west side.
