This dataset is derived from the WOODIV database (available at: https://www.nature.com/articles/s41597-021-00873-3). It contains the grid cells of sites (10 km x 10 km horizontal resolution) sampled in Portugal, Spain, France, and Italy (Mediterranean part) for which at least one of the 24 Conifer tree species occurs.
This dataset exemplifies the argument site_locations used in
several functions of funbiogeo. The variable site corresponds to the
site labels (must match the same column in site_species) and the variable
country will be used as a site grouping factor.
Format
An sf POLYGON object with 5,366 rows (grid cells) defined in the
ETRS89-extended / LAEA Europe Coordinate Reference System (EPSG:3035).
