Presentation by Jeannie Hernandez, Quality Assurance Specialist II with San Antonio River Authority

Slow Down Burden, Spread Out Teamwork, Sink In Impact

The Residential Rain Garden Club at The San Antonio River Authority is a group of like-minded people who enjoy sharing expertise and solving landscape problems. For the past 10 years our group has worked to solve drainage issues with nature-based practices including rain gardens, pollinator swales, and replacing turf grass with native plants on member-owned properties. Our volunteer efforts have resulted in many residential projects that improve landscapes for the homeowner, wildlife, and the watershed. Our team has worked hard to implement solutions, teaching and learning as we grow a community of watershed wise stewards.

Jeanette Hernandez is a Quality Assurance Specialist II currently holding the position of Deputy Quality Manager for the San Antonio River Authority TCEQ Laboratory Accreditation Program. She also serves as the Laboratory Quality Assurance Officer for the Texas Clean Rivers Program (CRP).

If you are attending in person, there is no need to register. However, if you are attending via Zoom, please register here before the meeting begins as late registration and entry will not be allowed. After registering, you will receive a confirmation email containing information about joining the meeting.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
