Abstract
This management plan has been prepared for the Lower Columbia Estuary Partnership and is intended to provide guidance for the improvement and protection of western painted turtle (Chrysemys picta bellii) habitat at the Sandy River Delta in Troutdale, Oregon. The Sandy River Delta is a 1500-acre natural area situated where the Columbia and Sandy Rivers meet. Its dynamic floodplain habitat supports a diverse assemblage of species, including the western painted turtle, an Oregon Conservation Strategy Species. A small, unknown number of western painted turtles utilize the wetland habitats of the Sandy River Delta, and the frequency in observations of these turtles has decreased over time. The habitat utilization of western painted turtles at the Sandy River Delta has likely been influenced by changes in site hydrology, disturbance by off-leash dogs, and the presence of invasive vegetation in key turtle habitat. To create this management plan, western painted turtle habitat at the Sandy River Delta was evaluated to determine the necessary management actions for habitat improvement and protection.
