These data were compiled to study the effects of severe drought and a concurrent large wildfire on a large population of southern Pacific pond turtles living in a rapidly drying lake. The study was done in collaboration with biologists from Ecorp Consulting in Santa Ana, California with funding from the Desert Tortoise Council. Data were collected in August and September of 2014. This worksheet contains the data that were used to analyze straight-line carapace length in cm and create a histogram of the size distribution and sex ratio of the population of southern Pacific pond turtles (n = 122) in Elizabeth Lake, Los Angeles County, California (Figure 4 from manuscript.) Carapace length was measured with tree calipers accurate to within + or - 1 mm. This worksheet also contains the data that were used to estimate abundance survivorship of southern Pacific pond turtles (Actinemys pallida) in Elizabeth Lake, Los Angeles County, California, USA based on daily survivorship calculations from August to September, 2014 (Figure 5 from manuscript).
