The data are presented in a single spreadsheet with the following sheets: The 'Environmental Data' sheet includes the site locations (longitude and latitude), percentage canopy cover, leaf litter depth, distance to the high water mark, and snake presence and absence information for the 50 locations with retrieved microclimat data. The 'Microclimate Summary - Day' and the 'Microclimate Summary - Night' sheets include the means and variances for temperture and absolute humidity data collected during the day and at night, respectively, for these 50 locations. The 'Microclimate Raw' sheet includes all the temperature and humidity data collected for the 50 sensors in these locations. The 'Snake Survey' sheet includes location and time information for all sea kraits that were encountered suring surveys for this study. The 'Vegetation Data' sheet has the cover abundance data for plant species data collected for all 37 transect points used in the study.
