“…Changes in species composition and structure are the basic component of forest dynamics (Fürst et al 2007;Klopcic & Boncina 2011), but in the last several centuries (Linder & Östlund 1998).These factors include unfavourable development of ungulate game population and high damage to forests. Game management is often preferred over forestry (Ambrož et al 2015; Konôpka et al …”

“…When defining the methods of their care, it is necessary to know how the forest would have spontaneously developed at given sites in the past (Klopcic & Boncina 2011). It is possible especially only in an original or natural forest where developmental processes not disturbed by primary anthropogenic activities are taking place (Tabaku 2000).…”

Knowledge of the structure and dynamics of near-natural mixed forests is a key factor for ecologically oriented management of forest ecosystems. The development of these model forests mostly takes place continually without any pronounced disturbances. Natural regeneration can be locally limited by ungulate browsing. The paper was focused on the structure and development of forest stands with emphasis on natural regeneration in relation to ungulates in Černý důl Nature Reserve and Trčkov National Nature Reserve situated in the Orlické hory Mts., Czech Republic. The case study was conducted in a spruce-beech-fir forest stand on four permanent research plots (PRP) of 0.25 ha in size. PRP are situated in the same stand and in comparable site and stand conditions, but two PRP has been protected against game by fencing since [1985][1986][1987][1988][1989]. The stand volume ranged from 478 to 565 m 3 ha −1 in age 143 -156 year. The results showed that the diversity of tree layer was higher by 19.8% (48.0% in species richness) in the stands protected by fence. In the phase of natural regeneration, the species composition, stand structure and number of recruits were poorer on unfenced PRP (7,990 recruits ha ). Admixed silver fir and rowan were completely eliminated by browsing (to 94 -100% of individuals). Growth analyses statistically confirmed that ungulates were a significant limiting factor for successful forest development (P < 0.001).

“…Silver fir was more resistant to low growth and had lower mortality in comparison with Picea abies (Vieilledent et al 2010). However, the decline of Abies alba in natural ecosystems is more often observed (Thomas et al 2002;Camarero et al 2011;Ficko et al 2011;Klopcic and Boncina 2011).…”

Context Taxus woodlands suffer from a lack of natural regeneration across its whole distribution range. Aims In Knyazhdvir Reserve in Ukraine Taxus baccata primarily competes with Abies alba. It has been assumed that in the conditions of deep shade, yews have a greater competitive advantage than firs. Methods To verify this hypothesis, a plot with both species growing under the canopy was established. Wood samples were taken from 20 trees of T. baccata and 20 trees of A. alba. Results There were no differences in the mean tree-ring width, height and age between both species. Due to a lack of spatial separation of both species, yews and firs inhabited the same area in the analysed plot. Fir seedlings (up to 0.5 m) were recorded to grow under yew saplings (above 0.5 m), but the inverse situation of yew seedlings growing under fir saplings was not seen. Conclusion Seedling distribution, tree-ring growth rate, possibility of growth of fir seedlings under yew saplings and greater potential growth suggested that fir was predisposed to having the competitive edge over yew. Our results may confirm the hypothesis that T. baccata has a restricted distribution because of weak competitive abilities and can exist only in habitats where faster growing species are absent. The results call into question the prevailing opinion that human influences are the principal cause for the decline of T. baccata.

“…According to Köppen classification, the climate is marked as Cfwbx. Because of being evenaged and consisting of only one tree species (>95% of growing stock), this type of forest is rarely found in forest management of European fir forests [18]. Stands which belong to the observed forest are extremely similar to each other in terms of timber stock, stand basal area and increment [10].…”
