英文摘要: A test was conducted on the relation between the intensity of bark stripping by Polish primitive horses and the directly measured degree of bark detachability. A DI (damage index) was calculated for particular tree species, using those measuring 5–20 cm DBH (diameter at breast height), separately for five DBH sub-classes. Bark detachability measurements were taken using a dynamometer in ten selected tree species. The results for eight of these species showed a decreased DI the greater the DBH value and distinct differences between species (with DI varying between 0 and 2.79). The force (N) and relative force (N/g dm) used to detach a piece of bark differed between species, but this difference was not always statistically significant. The force required to detach bark generally decreased with DBH subclass, whereas this tendency did not apply to the relative force. A regression model explained less than 20% of the DI variability, and extent of damage (DI) significantly decreased with the mean relative force. Based on these results, it can be concluded that relative force (that required to detach 1 g of bark) is one of the direct factors influencing the selection of different tree species by horses. © 2016 Elsevier B.V.
