Abstract
Texas Parks and Wildlife Department (TPWD) regulates the commercial trade in 177 amphibians (51) and reptiles (126) with two lists: the White List (species can be commercialized) and the Black List (cannot be commercialized). I evaluated the appropriateness of assigning species to the lists from five perspectives, or factors: Available habitat, reproductive potential, relative abundance, demand in trade, and a combination of all four. Species list placement using data for all four factors had little agreement with TPWD lists, e.g., a comparison based on all factors combined was only 56%. A ranking system and 12 recommendations are provided to assist future management efforts.
