Abstract
  • We compiled Western Pond Turtle (Actinemys marmorata) and Painted Turtle (Chrysemys picta) locations in northwestern North America, consolidating data from multiple sources including nine U.S. State and Canadian Provincial jurisdictions. We assessed numbers of discrete locations, and analyzed distribution patterns temporally and spatially. Western Pond Turtle observation records ranged from years 1850 to 2011 and for the Painted Turtle, from 1805 to 2011. For the Western Pond Turtle, 2,935 locations were compiled range-wide; using a 500-m buffer criterion to aggregate adjacent coordinates, we consolidated these to 2,111 discrete sites. We compiled 2,953 locations for the Painted Turtle, which consolidated to 1,219 discrete sites in the United States using the same 500-m criterion. Our occurrence maps and spatiotemporal patterns can be used to advance new efforts toward northwestern North America turtle management.
