Count represents the total number of observations (animal relocations) during which a koala was observed on an individual tree species. The data presented for tree diameter at breast height (DBH), tree height, and koala height in trees represents the mean data for all koalas surveyed in each environment. The tree species shown represents > 95% of animal relocations in each environment.
