3.4.4 Roadside Pest Management Program

Texas is divided into ten vegetation regions (see ) and the State is known for its biodiversity, but at least nine species have disappeared completely. TxDOT, through the , has identified candidate, threatened, and endangered species, as well as vegetation considered to be a targeted species for removal. As part of the aesthetic design, best practices would include:
  • Inventory and identification of existing roadway vegetation species; and
  • Designation of those areas to be preserved and possibly enhanced within the proposed design.
