THE USE OF THE RESISTOGRAPH ON THE EXAMPLE OF THE PROTECTED LANDSCAPE "ZELENJAK

Cilj ovog rada je utvrđivanje zdravstvenog stanja stabala u neposrednoj blizini "Staze kroz krošnje Zelenjak" koja se nalazi na području zaštićenog krajobraza "Zelenjak". Istraživanje je provedeno na 13 stabala u rujnu 2022. godine. Na stablima je provedena njihova vizualna analiza VTA metodom (Visual Tree Assessment) i mjerenja promjera, a zatim su rezistografom izvedena mikro bušenja. Rezultati istraživanja pokazuju da su sva stabla zdrava i statički sigurna. S obzirom da ovu šetnicu svakodnevno posjećuje veći broj ljudi, što predstavlja dodatni stres okoline na stabla, ističe se potreba da se ispitivanje stanja stabala ponovi kroz određeno vremensko razdoblje, odnosno da se monitoring nastavi.The aim of this research was to determine the health status of trees in the immediate vicinity of the "Zelenjak Canopy Path" located in the area of the "Zelenjak" protected landscape. The research was conducted on 13 trees in September 2022. The trees were visually analyzed using the VTA method (Visual Tree Assessment). Diameter measurements were firstly made and then micro-drilling was performed with a resistograph. The results of the research show that all trees are healthy and statically safe. This promenade is visited by a large number of people every day which represents additional environmental stress on the trees so the need to repeat the examination of the condition of the trees over a certain period of time, i.e. to continue the monitoring, is emphasized
