Freshwater turtles are especially susceptible to environmental changes such as habitat fragmentation and riparian modifications (e.g., dam construction). These changes, which influence stream flow, also produce nesting area inundation. Moreover, these chelonians are pursued for their commercial value as pets. Phrynops williamsi is a species severely impacted by habitat fragmentation. Its distribution in Uruguay has been significantly reduced and only the most austral population remains (Paso Centurión locality). In Brazil and Argentina, population status is unknown. Rivers and streams with prior capture data have been modified by dam construction. Currently, P. williamsi is considered “Endangered” in Uruguay by IUCN, “Data Deficient” in Argentina, and “Endangered” for Paraná State, Brazil. In Uruguay it is included in the “Official List of Species of the Wild Fauna” (Decree 514/001) and protected by law (Decree 164/996). Although only the trades of in captive individuals are permitted, the extraction of wild populations still happens. Around 20 specimens per year are exported from Uruguay as captive bred individuals when indeed they are not. If we consider that only one population is confirmed for Uruguay and that exported individuals are wild captured, the number of exported individuals is vitally important. Moreover, this population is found in marginal distribution of species range, and for that reason population density should be low. The capture of wild individuals is incremented by international demand and they are sold for 500 € in European market. It is crucial to continue the study if wild populations in order to influence management plans for species conservation. Furthermore, local communities and governmental institutions need to work more closely together to diminish species trade.
