Join us on an exciting journey into the mysterious world of bats and their habitat right here in the Hill Country! Krystie Miner of Bat Conservation International (BCI)’s Bracken Cave Preserve in San Antonio, TX, will unravel the myths and facts surrounding these fascinating creatures, shedding light on their often misunderstood reputation. 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

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 four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
