She’ll dive into the critical importance of bats in the Hill Country, from their crucial role in controlling insect populations to their remarkable adaptations for survival. Whether you’re curious about their habitats, behaviors, or how they contribute to maintaining the delicate balance of our local environment, this talk promises to be both informative and eye-opening. Don’t miss the chance to learn more about these incredible nocturnal creatures and the rich habitat they call home!and. Join us at our Tuesday March 4th chapter meeting!

Krystie Miner began working with Bat Conservation International (BCI) in January 2023 as the Project Coordinator for Bracken Cave Preserve in San Antonio. She coordinates volunteers to lead tours of Bracken Cave and to help with numerous other research, conservation, education, and citizen science projects. She also aids in other BCI projects as needed, including White-Nose Syndrome surveys and swabbing agave plants for eDNA.  

Krystie has a background in wildlife research and conservation and has been working with bats since 2014. She has a B.S. in Ecology from Boise State University and an M.S. in Conservation Biology from Texas State University. In addition to working with bats, she has previously worked with birds, insects, and fish, though bats remain her biggest passion. She resides in San Antonio, Texas, where she is within a half hour drive to Bracken Cave and spends her spare time exploring the hill country with her dog.  

Bat Conservation International’s mission is to conserve the world’s bats and their ecosystems to ensure a healthy planet. They are dedicated to prevent the extinction of bats, the world’s most vulnerable wildlife, and they focus on the rarest and most vulnerable bats and their habitats. 

Bracken Cave Preserve is located north of San Antonio, Texas. Bracken Cave is the summer home of more than 15 million Mexican free-tailed bats (Tadarida brasiliensis), making it the world’s largest bat colony and one of the largest concentrations of mammals on earth. The centerpiece of Bat Conservation International’s Bracken Cave Preserve is, of course, the cave and the millions of bats that live there. But BCI is also involved in the stewardship of the preserve’s 1,500 acres of hills, canyons, woodlands, and grasslands.

The meeting will start with a social time at 6:00pm, at Hunke Gathering Hall at Herff Farm, 33 Herff Road, Boerne. Announcements will begin at 6:45pm, followed by the presentation. For the social time, please bring any snacks/appetizers/desserts that you would like to share.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
