The study uses the methodology of ecological field theory to model the effect of Scots pine seed trees on the density of tree seedlings and other plants in the field layer. The seed trees had a clear effect onthe expected value of the amount and distribution of the ground vegetation. The vicinity of seed trees had an adverse effect on the growth of grasses, herbs and seedlings, while mosses were most abundant near the trees. Models based on the ecological field approach were derived to describe the effect of seed trees on the ground vegetation.
