Explanatory variables of vascular plant species diversity depend on study scale. In the continental-scale, amount of solar radiation and the availability of water explain plant diversity well in the northern hemisphere. In the landscape level climate is not a significant determinant. On the local scale the plant species diversity is affected by abiotic and biotic factors. In a boreal forest, the amount of nutrients, water economy and the amount of light explain the species diversity. Furthermore, the activities of humans have a significant effect on the species richness of plants. It increases because seeds disperse with humans to new areas. The activities of humans cause disturbances and add to the environmental heterogeneity. While the quantity of habitats increases, the species richnes also increases. Intermediate disturbances lessen the competition and maintain the various phases of succession. In this research I have modeled factors affecting all vascular plant species and native species richness in the region of southern boreal forest. I assumed the activities of humans were the most significant factor affecting the number of all plant species. Native species, which arrived to the region before the 17th century, were assumed to be more dependent on abiotic factors. Plant survey material gathered from 286 square kilometers in the municipality of Luopioinen was used in this research. The plant species richness on a square kilometer rectangle was known and it was explained using variables calculated from geographic information using a Generalized Additive Model (GAM). Thirteen variables, which were abiotic, biotic, or explaining environmental heterogeneity were fitted into the model. The result was that species richness of all vascular plants was best explained by the impact of humans, nutrient level of the soil and the heterogeneity of the environment. The results were fairly similar to previous research. The native species didn't behave in the model like I assumed. The diversity of the native species was explained by the impact of humans, nutrition level, water economy and the heterogeneity of the environment. The model for the native species was very much like the model for all species. There were only three additional variables and the level of determination of the model was lower. The used modeling approach cannot detect causality, so the impact of humans on the native species, which came as a surprise, could be explained by the fact that human settlements can have emerged on already species rich regions instead of being randomly distributed.
