In a study of tree dispersion in a forest, we divided the forest into 1 sq km grid cells, choose 50 of them at random, and counted the number of trees in each cell. The means to variance ratio of the counts of trees per cell was much less than 1. What does this tell us about the spatial distribution of the trees?
