Painted turtles are North America's most widespread freshwater turtle, but they face mounting pressures from road mortality, nest predation, and climate-driven temperature shifts.
Road mortality during nesting migrations is the most significant anthropogenic welfare concern for painted turtles. Females crossing roads to reach nesting sites are struck by vehicles, often fatally. Because painted turtles are long-lived and slow-reproducing, loss of breeding females has disproportionate population impacts. Individual turtles struck by vehicles suffer traumatic injuries including shell fractures and internal injuries that cause prolonged suffering if not treated. Wildlife crossing structures and temporary fencing to guide turtles under roads substantially reduce road mortality. Climate change threatens to skew sex ratios toward females as incubation temperatures rise, potentially reducing male availability and reproductive success in the long term.
