Statistics for each 15 km X 15 km grid cell, for all California native vascular plants, as studied by Baldwin et al. (2017 Amer. J. Bot.), including randomization results.

Shown in columns in this Excel spreadsheet are (1) Cell identifier; (2
& 3) X and Y coordinates for the centroid of each grid cell, using
the California Albers (EPSG:3310) coordinate system; see
http://spatialreference.org/ref/epsg/3310/ ; (4) Observed species
richness; (5) Observed redundancy (1 - [richness / number of specimens]);
(6) Observed weighted endemism (1/number of cells occupied by a species,
summed across all species in a cell); (7) Observed corrected weighted
endemism (WE/cell richness); and (8) Number of randomizations with a CWE
score lower than observed; 950 and above is considered significant. All
calculations and indices are from the Biodiverse software package (Laffan,
S.W., Lubarsky, E. & Rosauer, D.F. (2010) Biodiverse, a tool for
the spatial analysis of biological and related diversity. Ecography. Vol
