Data on tree size, competition and mistletoe occurence on individual stems

Data used in the article to test effects of tree size, neighbourhood competition and distance from nearest infected tree on probability of mistletoe infection and number of mistletoe plants on individual stems. Tree size is represented by diameter at breast height (DBH), competition by Hegyi competition index (CI_stem) and by number of trees in 12m radius around a tree. Distance data stand for the nearest distance to an infected stem infected by mistletoe of given minimum size (diameter in cm). Infection by mistletoe is indicated by 1 = infected, 2 = not infected.
