Your neighbors, family, friends, employers, and colleagues are the members and supporters of Green Spaces Alliance. Â We all treasure the uniqueness of the South Texas region â€“ from the Edwards Plateau to the South Texas Plains, from the Hill Country to the prairies. Â Green Spaces works hard to protect the clean air and safe drinking water that we enjoy today. Â Population growth in the region is projected to almost double in the next 50 years. Â Urban growth, without careful planning and preservation, will disrupt our quality of life unless we act today. Â Green Spaces Alliance has one mission: Â Our mission is to sustain the natural environment and enhance urban spaces through land conservation, community engagement and education.
