Data for Local nutrient addition drives plant diversity losses but not biotic homogenization in global grasslands

The files include: 1, raw cover data for control and nutrient addition by NPK in year 4 and year 14 at 72 NutNet sites. 2, raw cover data for sites have five blocks in year 4. 3, sites with geolocation and experimental years used, 4. site drought index, 5. site herbivores. 6, site productivity. 7, site species pool, 8. minimum area and distance among blocks, and generated dataset of 9. effects of nutrient addition on diversity across scales.
Methods for estimating cover and species richness, definitions and quantification for site covariates (i.e. site drought index, site herbivores, site productivity, site species pool, and minimum area and distance among blocks) can be found in the method section of the main text.
