Land use data and anuran species richness for North American Amphibian Monitoring Program survey sites

Data from 587 NAAMP survey sites. NAAMP survey locations are organized as "stops" within "routes," each of which has a unique SiteID. Land use variables were measured within buffers of 300m, 600m, 1000m, 5km, and 10km. Variables include "wet_prop" (proportion of area covered by wetland), "imperv" (proportion of area covered by impervious surface), "PROP_FOR" (proportion of area covered by forest), "PROP_DEV" (proportion of area covered by developed land uses, and "PROP_AGR" (proportion of area covered by row crop agriculture. Road-related variables are given as linear lengths (meters) within each buffer. Variables are T_ROAD_LEN (total road length), P_ROAD_LEN (primary (divided) roads), S_ROAD_LEN (secondary roads), O_ROAD_LEN (other roads, i.e. not P or S), and PS_ROAD_LEN (the sum of primary and secondary road lengths). Data also show the number of NAAMP surveys of each stop (Num.Surv), the number of years covered (Num.Years), mean car count during surveys (Car.Count), number of surveys with ambient noise (Noise.Num), and proportion of surveys that noted noise (NOISE_LEV = Noise.Num/Num.Surv). Amphibian presence/absence over all surveys are given for the species ANFO, HYCI, HYSQ, LICA, LICL, LIPA, LIPI, LISP, LISY, HYCV, PSTR (full scientific names are provided in the associated paper). NAs indicate sites outside the known range of each species. Richness is shown as the sum of all species detected at each stop, and NPP represents estimated Net Primary Productivity at that set (which provided a geographic expectation of anuran species richness).
