This dataset includes location and genetic data for Blanding's turtles sampled in Wood County, WI. The first sheet ("NestingFemaleData") includes data for females captured during terrestrial nesting surveys. Nesting areas are as described in the publication; any turtle captured outside of the seven main nesting areas identified are listed as "other". The second sheet ("NonNestingData") includes all other turtles, including adult males, adult females captured in aquatic locations, and juveniles of unknown sex. For all location data, "X" and "Y" are UTM coordinates (UTM zone 15N, WGS84 datum). When individuals were captured more than once, coordinates represent the centroid of all capture points. Missing data for microsatellites are represented as "xxx".
