PR (landscape level)
Description
Patch richness (Diversity metric)
Usage
lsm_l_pr(landscape)
Arguments
landscape
A categorical raster object: SpatRaster; Raster* Layer, Stack, Brick; stars or a list of SpatRasters.
Details
PR = m
where m is the number of classes
PR is a 'Diversity metric'. It is one of the simplest diversity and composition measures.
However, because of its absolute nature, it is not comparable among landscapes with
different total areas.
Units
None
Range
PR >= 1
Behaviour
Equals PR = 1 when only one patch is present and increases, without
limit, as the number of classes increases
Value
tibble
