In order to test the effect of grazing treatment on the two biodiversity metrics, richness and unicity, and on forb:graminoid ratio and litter amount, while considering block, topography and treatment, All parameter variables are continuous, except for species richness, withered intercepts and sensitive species, which only consist of integers. The values for species richness, unicity and Ellenberg L were normally distributed, whereas the values for sensitive species, Simpsons diversity and evenness, the ratio of forbs to graminoids, withered intercepts and Ellenberg N had skewed distributions. Block location in either the hills or on the old seabed beneath the Littorina slope was identified in the field and in the subsequent analyses as a significant factor for several parameters.
