Summary
These data are CSV files comprised of a heading and tables from Appendix 1 and Appendix 2 in the accompanying paper. The tables show the sampling dates and locations for the coachwhip (Masticophis flagellum) and striped racer (Masticophis lateralis) in pit-fall arrays (Fisher et al. 2008) monitored in southern California from 1995-2000. GPS data are shown in decimal degrees and were collected in the field using the WGS84 datum system. Elevation is in meters. Columns in the tables include a site ID number assigned to each site name, the year and calendar dates each site was sampled, number of arrays, number of sampling days, number of sampling occasions, and whether or not each of the target species were detected on that particular [...]
