Article abstract: Data Summary. To document occupied areas in southern California, record demography of remaining pond turtle populations and assess suitable habitat, the U.S. Geological Survey (USGS) conducted pond turtle specific surveys throughout Los Angeles, Orange, western Riverside, and southwestern San Bernardino counties. These surveys included habitat suitability assessments to determine whether appropriate habitat existed at survey locations, as well as identifying threats from invasive species, especially the presence of non-native turtles. Pond turtles were also detected during surveys focused on other species, but no habitat assessment was done at those sites.
