Detection and non-detection records of Saipan's terrestrial herpetofauna, 2018

Metadata Updated: July 6, 2024

There are two datasets included in this entry. The diurnal dataset contains 28 columns of data collected during transects surveys. The nocturnal dataset contains 52 columns. We randomly select 56 sites, each 50 m in length, from 37,968 m of transects spanning the island that were originally created for bird surveys in 1982 through the cooperative efforts of the U.S. Fish and Wildlife Service, the Department of Natural Resources of CNMI, and the U.S. Forest Service. For diurnal surveys, 56 transects were surveyed twice per day for 1–3 consecutive days resulting in six survey occasions. For nocturnal surveys, we surveyed 51 of the 56 transects 4 times per night for 1–3 consecutive nights resulting in 12 survey occasions. Each survey was alotted ~10 min to complete. All species encountered during this time were recorded. The covariate enhanced vegetation index (10-meter resolution) was derived using Sentinel-2 satellite imagery from dates around and through the sampling periods: 12 June 2018, 22 June 2018, 02 July 2018, 22 July 2018, 27 July 2018, and 11 Aug 2018. Elevation data was resampled to 5-m resolution from a native 3-meter resolution.
