The study conducted in the year 2011 aimed at the determination of the health state of selected urban trees and the quality of their habitat (using two simple methods), and then the characterization of the correlations between them. The analysis included five areas of the town of Oświęcim (Silesian Voivodeship, Southern Poland), differing in tree habitat conditions. The health state of the trees was evaluated based on the health scale developed by J. Duda, and the habitat quality was determined on the basis of the scale proposed by Jendrzejczak, Buczkowska and Chojnacka, modified by Mazuruk and the authors of the article. The study included 424 trees of 22 species. The most numerous were: the small-leaved lime Tilia cordata – 16,7% and broad-leaved lime Tilia platyphyllos (15,8%). The majority of the trees (as many as 76,2%) were in good health condition, and the largest group (38%) consisted of the specimens on the habitat of average quality. The trees on the habitats of very high and average quality were characterized by the best health state, and the trees on low quality habitats were in the worst state of health. The research has shown, that the quality of tree habitat is not always directly responsible for its health state. This may result, inter alia, from the fact, that the trees growing in the exposed stands and posing a real threat to pedestrians and traffic, are more often subjected to care treatments directly influence the result of health state assessment.
