The Zapata Bladderpod (Physaria thamnophila; Brassicaceae) is a federally and state endangered species endemic to the Tamaulipan thornscrub of South Texas with documented occurrences in Northern Mexico. In this project we documented the breeding system, flower visitors, reproductive success, and seed germination of this species. From 2022-2024, data were gathered at eleven sites ranging from federal, private, and NGO lands. All the data gathered during this project has expanded our knowledge of the biology and ecology of Physaria thamnophila and can contribute to future reintroduction efforts for the species. The latter is extremely important due to the anthropogenic pressures associated with habitat loss and degradation facing Physaria thamnophila and the Tamaulipan thornscrub in south Texas.
