February 2024 Presentation by Wendy Leonard
A Rare Texas Native-Conservation of the Bracted Twistflower (Streptanthus bracteatus)

Explore the factors limiting the growth and distribution of a true Texas Native, the endemic Bracted twistflower (Streptanthus bracteatus).  A member of the Brassicaceae (mustard) family, S. bracteatus is a rare wildflower growing exclusively in the Edward’s Plateau ecoregion.  With less than 12 populations remaining, the species was listed at threatened in 2023.  Much of the populations that remain are experiencing decline due to a number of factors including genetic inbreeding, mismanagement of habitat, residential development, and over browsing by deer, just to name a few.  Wendy Leonard will discuss conservation efforts for Bexar and Medina Counties and the work being done to help save this species.    

Wendy Leonard has been with the City of San Antonio for 19 years.  She has a BS in Wildlife Biology and Geography: Resource and Environmental Studies from Texas State University-San Marcos and a Master’s of Science in Biology with thesis in Plant Ecology at the University of Texas at San Antonio.  Her thesis research focused on the factors limiting the growth and distribution of a rare Texas endemic wildflower. In the City of San Antonio Natural Areas, she manages native plant communities, surveys and monitors rare and endangered species and conducts research and restoration projects.
