#---------------------------------

Data contains species richness of plants, earthworm, spiders and bees (wild bees and bumblebees) in 195 farms in 12 study regions in Europe. The observed species richness are complemented by a 5% lower and a 95% upper confidence level derived from species accumulation as well as the number of samples drawn in each farm.
