Static Pulling tests can be used for urban and forest trees

Static pulling tests were performed to compare the mechanical stability of Eurasian aspen (Populus tremula L.) and silver birch (Betula pendula Roth.) in both urban and peri-urban forests. The loading resistance of the species differed, with birch being more stable than aspen. Additionally, the mechanical stability of birch did not differ between trees growing in urban and peri-urban forests, suggesting static pulling tests are a suitable method for comparing trees from completely different growing conditions.
