We apply the machine learning approach of induction of regression trees to biological and chemical data collected through regular monitoring of rivers in Slovenia. A predictive model is built, which identifies the most important parameters for predicting the species richness (the number oftaxa) of the community: these include biological oxygen demand (an overall indicator of pollution), water temperature, the season (month), total hardness, NO3, SiO2 and alkalinity.Text/Conference Paper
