Coefficient of correlations between the matrix of environmental (habitat/land-use) variables and the 4 axes of the CCA ordination scores. Different levels of significance of Spearman rank coefficients of correlation of the environmental variables with axes: * ; ** ; *** ; ns: . Correlations indicate the degree to which species occurrence and distributions correspond to changes in each variable in the environmental matrix.
