Covariates and coordinates for prediction of relative warbler abundance in Pennsylvania, USA
Description
Bioclimatic and land cover variables extracted at a 12km resolution across the state of Pennsylvania, USA for use in predicting relative abundance of six warbler species across the state. Land cover data come from USGS EROS, while climate data come from PRISM.
Usage
data(bbsPredData)
Format
bbsPredData is a data frame with seven columns:
bio2: bioclim variable 2.
bio8: bioclim variable 8.
bio18: bioclim variable 18.
forest: proportion of forest cover within a 5km radius.
devel: proportion of developed land cover within a 5km radius.
x: the x coordinate of the point. The proj4strig is "+proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=37.5 +lon_0=-96 +x_0=0 +y_0=0 +datum=NAD83 +units=m +no_defs".
y: the y coordinate of the point. The proj4string is "+proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=37.5 +lon_0=-96 +x_0=0 +y_0=0 +datum=NAD83 +units=m +no_defs".
