SHAPEFILES

LandoutlineCEA2 – Outline of the world map

GridCEALand - shapefile with one polygon for each of the
terrestrial grids used in the analyses. The unique identified for each cell
grid (to match with other files) is PageNumber

GridMammalsCEA - shapefile with data for each of the
terrestrial mammals overlapping each terrestrial grid described in GridCEALand.
This file was used to calculate grid statistics presented below.

CSV FILES

RoadlengthGrid.csv – sum of all paved roads in each cell grid. The
unique identified for each cell grid (to match with other files) is PageNumber.

GridStats.csv - summary statistics for each grid cell
described in GridCEALand shapefile.

Metadata – description of all steps to prepare Figure
