Urban forests are forests near cities and settlements and are being given increasing importance today. Function of urban forests is to improve the quality of life of residents by providing them with ecological, aesthetic and social significance in the urban environment. In a broader meaning, these are individual trees (solitaires), tree-lined avenues, alleys, parks and park forests. According to the Nature protection law (2019) the purpose of the park-forest is conservation or planting forests of greater landscape value, rest and recreation. One of the most important functions for the health of people in urban areas is recreational function. For the forest to fulfill its recreational function it has to be in a good condition considering the environment, level of development and health status that can be achieved by assessment of the trees.The aim of the research was to make an assessment of the trees in the park-forest Borik in Đurđevac, at the training stations along the trim track in order to propose certain interventions on trees and the environment of the trim track that would improve the use of space and safety of the visitors. The research was conducted on a trim trail located in the Borik forest in the town Đurđevac. The trim track is a sports and recreational facility within the Borik forest park as a protected area and within certain surrounding sections of GJ "Đurđevački peski" which are not under protection. Cultures of black and common pine and common acacia are represented. 17 stations located within the trim trail were analyzed. Circles with an area of 2000 m2 were formed and a visual assessment of trees with a diameter of more than 10 cm at a height of 1.30 m was performed inside them.The obtained research results show the connection between vitality ratings and final grades, with vitality scores slightly higher than final grades at all stations. The removal of trees located at the initial stations of the trim track is envisaged. The common acacia is the species that is mainly being removed. In conclusion, the stations within the park-forest differ from the stations outside the park-forest area by number of trees, by percentage of removing trees and by the assigned final grade.
