    Opis:
    The lack of knowledge about seasonal dynamics and impact of deer browsing on deciduous saplings in plantations in managed forests in Poland raises difficulties in assessing the impact of cervids on forests and in selecting effective methods for protecting plantations against damage caused by deer. The studies covered 1129 saplings of sycamore, oak, beech, linden and birch species that were planted on the unfenced sites accessible for animals and fenced sites left for comparison.

    Opis:
    Assessment of the impact of large herbivores on young generation of trees in the protected forests can support decisions about whether to intervene in natural ecosystems (e.g. individual tree protection, animal culling) or not. A study on the condition of forest regeneration, including the assessment of the damage caused by deer, was performed in the Gorczański National Park (GNP; southern Poland) in 1993 for the first time. The inventory was repeated in 1996 and 2011 on the same 415 concentric permanent sample plots located in the centers of 400×400 m grid. Trees with diameter <16 cm or height 1.3 m were counted. The impact of deer was assessed using: (i) the share of browsed terminal shoots in h=0.3−1.3 m class trees and the tolerable (based on a reference) share of browsed trees of such height with the most damaged tree species taken into account and (ii) the proportion between the density of recently (the previous year) debarked, frayed or broken trees and the tolerable (based on a reference) density of such trees. The main interpretation unit was composed of all stands in the GNP, while stands in particular protection districts formed lower level. Over the time, the density of trees in the regeneration layer increased (fig. 1). The density of recently debarked (frayed or broken) trees decreased considerably (fig. 2), even if a large number of trees (especially silver fir) with old wounds existed (fig. 4). The density of the browsed trees remained more or less unchanged. This type of damage most frequently affected silver fir, sycamore maple and rowan (fig. 3). Differences between the level of forest regeneration damage in different protection districts of the GNP remained similar (fig. 5). The deer impact assessed on the basis of the density of debarked trees significantly decreased to be classified as tolerable in 2011. However, the impact assessed with the share of trees with the browsed terminal shoot did not reach the tolerable level in one protection district. Results show that measures undertaken to protect forest regeneration produce a partially positive effect. The browsing level was still too high. Differences in the deer impact on the forest regeneration between protection districts can be considered as permanent ones.

    Opis:
    The results of the inventory of damage caused by roe deer in a 2−year−old apple orchard in central Poland permitted to evaluate the browsing intensity as well as the relationship between biometric characteristics of trees and browsing intensity. The research showed that damage caused by the roe deer was mainly caused by shoot browsing, then rubbing the velvet antlers against trees and bark stripping. In one winter, roe deer damaged 35% of the orchard by browsing even up to 100% shoots on an individual tree. Significant differences were found between the intensity of browsing the different varieties of apple trees. The largest damage was noted in the case of the Ligol variety (35% of shoots on average), while the smallest – for the Idared and Golden Delicious varieties (approximately 5% of shoots on average). Branching and tree height were not found to affect the level of damage. When establishing forest hunting grounds, the Ligol variety, eagerly browsed by roe deer, should be planted on browsing plots, while Idared and Golden Delicious varieties – in orchards designed for fruiting.
