Natural Features: Trees such as Mountain Laurel, Ashe Juniper, Mesquite and Live Oak abound, as well as Mexican Buckeye, Lindheimer’s Silk-Tassel and Escarpment Black Cherry. Steep slopes provide scenic overlooks of the surrounding Bexar County and glimpses of San Antonio. Rare birds such as the Golden-cheeked Warbler can be found. Geologically, the Natural Area lies on the Balcones Escarpment, an area of deeply entrenched canyons that defines the eastern boundary of the Edwards Plateau. Approximately 88% of the Natural Area overlays the Edwards Aquifer recharge zone. The remaining acreage overlies the transition zone for water recharge.
