  1. For each of the six group defined by species/sites indirect clustering, the most indicative species is indicated under the group. The percentage (number of sites) correctly classified by the environmental analysis is provided as well as the number and name of misclassified sites and groups in which they were placed. The coefficients of the linear discriminant function are provided for each environmental factor and each group.
