Abstract:In this study, we investigated the health status of balsam poplar (Populus balsamifera L.) trees in a residential area of the city of Bratsk (Irkutsk Oblast, Russia). Visual and instrumental assessment of the health status of pruned and unpruned trees was performed. The identified internal defects in the tree were analyzed with a Resistograph device, which enabled the extent of decayed wood to be determined. Visual analysis revealed various types of damage: dried branches, brittle crowns, frost cracks, mechanical damage, curvature of trunks, decay and inclusions of foreign bodies. We compared trees with and without canopy pruning. We found that pruned trees were significantly more damaged than non-pruned trees. Decomposing wood at different stages of development was found in all the trees studied. A tree passport combining the visual and instrumental assessment data was compiled for each tree. The results of the research were used to formulate conclusions and recommendations for improving the management of urban trees in order to restore their ecological and aesthetic functions.

Title:Ocena stanja balzamastih topolov (Populus balsamifera L.) v stanovanjskih delih Bratska
Abstract:V tej študiji smo raziskovali zdravstveno stanje balzamastih topolov (Populus balsamifera L.) v enem izmed stanovanjskih območij Bratska (Irkutsk Oblast, Rusija). Opravljena je bila vizualna in instrumentalna ocena zdravstvenega stanja obrezanih in neobrezanih dreves. Ugotovljene notranje napake v drevesu smo analizirali z napravo Resistograph, s katerim je mogoče ugotoviti obseg razkrojenega lesa. Vizualna analiza drevesa je pokazala različne vrste poškodb: posušene veje, lomljive krošnje, mrazne razpoke, mehanske poškodbe, ukrivljenost debel, razkroj in vključke tujkov. Primerjali smo med drevesi z in brez obrezovanja krošenj. Ugotovili smo, da so bila obžagana drevesa bistveno bolj poškodovana kot neobžagana. Razkrajajoči se les je bil ugotovljen pri vseh preučevanih drevesih, vendar v različnih razvojnih fazah. Za vsako drevo je bil izdelan drevesni potni list, ki združuje podatke vizualne in instrumentalne ocene drevesa. Rezultati raziskave so bili uporabljeni za oblikovanje zaključkov in priporočil za izboljšanje gospodarjenja z mestnim drevjem zato, da se je lahko obnovila njihova ekološka in estetska funkcija.
