Arboristični popis dreves predstavlja pomemben sestavni del urbanega gozdarstva, ki nam omogoča ohranjanje vitalnost dreves, ki so varna za okolico. V mestni občini Radovljica smo na šestih izbranih lokacijah popisali skupaj 161 dreves z vizualno metodo s tal ter vizualno metodo iz zraka s pomočjo drona. Drevesom smo s pomočjo obeh metod določili višino, premer debla, simetričnost krošnje, vizualno ocenjevanje krošnje, vitalnost, določili ukrepe, ocenili stanje korenin, socialni položaj ter vrsto in vzrok poškodovanosti. Največja razlika med metodama se je pokazala pri ocenjevanju oblike krošnje, pri kateri se je vizualna metoda iz zraka izkazala za prednostno. Vizualna ocena iz zraka se je izkazala za dobro dopolnilo vizualne ocene s tal v primeru ocenjevanja krošnje in njene simetričnosti ter oceni vrste poškodovanosti vej in vrha. Izvedba obeh metod ocenjevanja dreves bi v prihodnosti lahko postala stalna praksa, ki bi nudila bolj celostno oceno stanja dreves in posledično boljše odločanje glede nadaljnjih ukrepov. Arborist tree inventory is an important part of urban forestry, which allows us to maintain the vitality of trees that are safe for the environment. In the municipality of Radovljica, we inventoried a total of 161 trees at six selected locations using the visual method from the ground and the visual method from the air using a drone. Using both methods, we determined the height, trunk diameter, crown symmetry, visual assessment of the crown, vitality, reinforcement, root condition, social status, and type and cause of damage. The greatest difference between the methods was found in the assessment of crown shape, where the visual method from air proved to be more advantageous. Visual assessment from above proved to be a good complement to visual assessment from the ground in assessing the crown and its symmetry, and in assessing the nature of damage to the branches and top. The use of both methods of tree assessment could become a permanent practice in the future, which would allow a better overall assessment of the condition of the trees and better decision making regarding further actions. |
