Format

A data.frame containing 49 variables describing covariates and other descriptors for the individual BBS observations. Variables include standardised information gathered by BBS (i.e. route IDs, temperatures, times, etc...) as well as GPS coordinates and percent cover for a range of landcover covariates. Landcover variables were accessed at 40km resolution, downloaded from MODIS Landcover Type 1, product MCD12Q1. See scripts at https://github.com/nicholasjclark/LandcoverMODIS for more details on MODIS downloads. PRISM climate variables were downloaded at 40km resolution using get_prism_monthlys and coerced into lagged variables representing climate conditions over the previous Spring (March - May) and over the previous year (July - June) before sampling occurred. Altitude data was downloaded at 40km resolution using the Aster Global Digital Elevation map. NDVI data was downloaded at 40km resolution using downloadGimms
