Opis (eng)

The "Jozića Koliba" memorial is located within the "Obrenovački Zabran" forest complex, which also includes the "Jozića Koliba English oak group", which is a level III protected monument. This natural monument consists of six English oaks (Quercus robur L.) with an average age of 250 years. Due to the effects of climate change and anthropogenic activities, all trees require intervention to maintain the overall attractiveness of the area. The tree number 1 requires immediate action to slow down its ageing and decay. The aim of this study was to analyse the state of health and the degree of deterioration of the protected tree number 1. Based on the results obtained, measures were defined to remedy the damage caused by biotic and abiotic factors. The investigation included recording the habitat-ecological conditions, dendrological parameters and the health of the tree. Boot damage was determined by visual inspection, sampling for laboratory tests and the use of an increment borer from inside the boot. The vitality and decorative value of the tree were assessed on the basis of these analyses using a modified VTA method. The analyses showed that the tree is dying due to its age and that this process is accelerated by ecological and, above all, anthropogenic factors. Based on the measurements, a cross-sectional model of the tree was created at the root collar and at a height of 1.5 metres. The percentage of the healthy part of the tree is between 10-85% of the total cross-section. The rehabilitation of the tree included cleaning the rot in the boot, disinfecting the cavity and filling it. Finally, a crown reduction was carried out by removing damaged branches. Support pillars were designed to improve and ensure the stability of the tree. The proposed restoration measures will extend the life of the tree and allow the area around the protected tree to be used safely.
