Predictive Mapping of Potentially Listed Rare Plant Species

The U. S. Fish and Wildlife Service (USFWS) has identified a number of rare plants that may be proposed for listing as threatened or endangered under the federal Endangered Species Act (ESA) in the next several years. Because the distribution and habitat requirements for many of these species is poorly known, TxDOT could be subject to increased numbers of surveys for these plants in the near future. Without well informed tools to identify areas that potentially support these species, TxDOT could be subject to significant survey cost and delays to ensure project compliance with the ESA. This project will identify existing populations and define habitat requirements (e.g., soils, land-use, and community associations) for these potentially-listed species. Distribution maps will be created and researchers will develop predictive metrics and models that will enable TxDOT to understand the likelihood of impacting these species in future projects, including identification of suitable habitat as well as areas that are clearly unsuitable habitat for the target species.
