  1. The environmental variables (Env. var.) used in the tests were: sampling period (S), Treatment (Treat) and the interaction of Time × Treatment (S × Treat), mean sward surface height (Heig), mean number of flowers (flow), percentage of grasses (gras) and percentage of forbs (forb). Covariables (Cov.): Block (B), sampling period (S), Treatment (Treat) and Plot Identifier (PI). The permutation scheme (Perm) on the whole plot level/ split plot level was: freely (F) or no permutation (N). %Axis: Cumulative percentage of variance of species data explained by Axis 1. F first, F all: values of F on the first ordination axis and all constrained axes respectively. P value: P values on all the ordination axes. Results of non-standardized tests are provided.
