Join the Nightlife: And Discover the World of Bats and Pecans​

Earlier this year, we partnered with Bat Survey Solutions to survey for bats at Swift River Pecans, where MTBC is currently testing characteristics of bat house success in Texas. The goal was to identify bat species using native pecan forests and cultivated orchards and to document their role in agricultural pest controlWe identified seven species using mist nets, harp traps, and acoustic monitoring, including Brazilian free-tailed bats, evening bats, and cave myotis. These species are known to occupy bat houses and other man-made structures, increasing the potential for attraction to bat houses on these properties. Many insect pests listen for bat echolocation and flee areas where bats are heard, making bat houses a unique tool for commercial growers.

This fall, we will be partnering again to bring you an educational workshop where you’ll visit the orchards along the San Marcos River in Central Texas, the birthplace of the commercial pecan industry. You’ll be immersed in the world of bats and agriculture, while learning field survey techniques including mist netting and acoustics. Participants will be able to see bats up close and view live echolocation recordings. This Discovery Workshop showcases a holistic approach toward commercial agriculture that safeguards native soils, water, and wildlife – including bats!

Dates: Thursday thru Saturday 22-24 September 2022

3 nights / 2 days

Cost: $275 per person before September 1, $325 after (LIMITED CAPACITY)

Activities: Thursday night kicks off with a picnic dinner and spectacular bat emergence at the famous Bracken Cave Preserve, just north of San Antonio.

Friday morning (9am) formal instruction begins and will conclude by Saturday night (10pm). Field trips include exploring Central Texas bat habitat, building artificial roosts, and visiting both commercial and native pecan groves to learn about sustainable agricultural practices.

Additional evening programs to see bats in the wild are planned for Friday and Saturday. We will capture live bats in the orchards with mist nets and harp traps and record the echolocation calls of bats flying overhead.
