Opis (eng)

A visual identification of tree species and an assessment of health status were carried out over the entire area of the urban forest. The presence of entomological and phytopathological diseases was determined through a detailed assessment. Carpophores of decay fungi belonging to the genera Ganoderma, Pleurotus and Phellinus and Schizophyllum commune Fr. (1815), were detected. These fungi cause the destruction of trees, which can lead to boot breakage. These fungi cause stem rot and severe damage in forests. On maple trees, the fungus Rhytisma acerinum (Pers.) Fr. 1818, causes chlorotic spots on the leaves in spring, which turn black in summer (tar spots on the leaves) and lead to premature leaf fall and continuously weaken the tree‘s vitality. This paves the way for other pests and diseases. All deciduous tree species have been found to be heavily infested by the widespread polyphagous species Metcalfa pruinosa (Say, 1830), which is often found in urban areas and causes a heavy secretion of honeydew. Sooty dew fungus is a fungal disease that grows on plants and other surfaces covered with honeydew, a sticky substance produced by this insect. After successive attacks, the assimilation functions decrease and the plants become physiologically weakened. There are also a large number of leaf miners: Tischeria ekebladella (Bjerkander, 1795) and Phyllonorycter robiniella (Clemens, 1859), as well as galls of the family Cynipidae and Cecidomydae. Numerous exit holes of bark beetles (Coleoptera:Scolytinae) were observed on the felled pines. Tumours and, less frequently, bacterial tumours were found on various species. Of the abiotic factors causing damage to the trees, ice fractures, frost cracks and bark cracks due to drought were observed. Numerous mechanical injuries were recorded as a result of human activity. The assessment of the current situation leads to the conclusion that the entire area is in a very poor state of health. Due to lack of maintenance and a number of abiotic and biotic factors, the overall health of the entire complex has been compromised. In the interest of the safety of all users, it is necessary to rehabilitate the area and reforest it in accordance with the biology of the species.
