Freshwater turtles depend on basking opportunities for thermoregulation, and loss of suitable basking sites is a significant welfare concern.
Turtles unable to bask adequately develop metabolic disorders and are more susceptible to disease. Waterways choked with invasive plants or developed shorelines eliminate basking logs and rocks. Road mortality during nesting season causes immense suffering and population decline. Illegal collection for the pet trade removes individuals from the wild.
