“…The P concentrations recorded in our study indicate that the P supply is limited on the site. Similar conclusions based on P availability in the area were published by Špulák and Dušek (2009). The P content upswing in 2008 might be a random deviation although it is too early to state it with certainty because the P concentrations in 2009 were still detectably higher as compared to those before 2008.…”

The aims of the paper were as follows: (1) to assess the applicability of speckled alder for pioneer stands on the mountainous clear-cut tracts and (2) to evaluate the effects of slow-release fertilizer on the survival and growth of speckled alder under harsh environmental conditions. On the basis of seven-year results we can presume that speckled alder is a convenient pioneer species that can be cultivated on harsh mountain sites where the climatic extremes need to be alleviated and a layer of surface humus renewed. The initial slow-release fertilization is, nonetheless, highly desirable. As contrasted to the control the surface and planting hole applications of amendment reduced the total seven-year mortality rate by 9.5% and 20.1%, respectively, and the periodic annual height increment (2003–2009) was promoted by 47% and 59%, respectively. Analogous results were obtained when the values of basal stem diameter and crown diameter were compared. As for the method of application, the placement of the slow-release amendment in the planting holes seems to be more efficient mainly in terms of survival promoting. The surface application is, nonetheless, less laborious and also yielded satisfactory results.

“…Pedological surveys in the locality revealed the accumulation of 153 tons of dry matter in organic horizons (L, F, H) under the blue spruce (Špulák, Dušek 2009). Reserves of N, P, K, Ca and Mg established by the Mehlich III method were 2.28 t, 3.8 kg, 71.7 kg, 140.0 kg and 41.16 kg per ha, respectively.…”

Sample trees were taken for analyses from an 18-years-old blue spruce stand growing in the summit part of the Jizerské hory Mts. (Czech Republic). The sample trees were measured and dry matter and nutrient contents were analysed in needles, branches, bark and stem wood. Based on the actual stand structure, correlations were calculated between the diameter, dry weight of components and nutrient reserves. Dry matter of the stand constituted 46% of the stand fresh weight. The highest amount of nutrients was accumulated in needles (from 42% in magnesium to 82% in phosphorus) and the lowest in the stem wood (from 2% in phosphorus to 15% in potassium). Regarding the character of the locality, the complete removal of aboveground biomass during tending operations represents a considerable loss of nutrients. If only the merchantable timber volume is processed, the loss of the elements from the ecosystem could be reduced to 8% (phosphorus) to 22% (calcium and potassium) of the total content of these elements in the aboveground biomass of removals.

“…Forest stands consist of Norway spruce ( Picea abies ) [ 41 ] and non-native silver spruce ( Picea pungens ) which was planted in Ore Mts. as a stress tolerant tree species into the pollution-damaged ecosystem [ 42 , 43 ]. The broadleaf tree species are mainly represented by downy birch ( Betula pubescens ) and common rowan ( Sorbus aucuparia ) [ 44 ].…”

We evaluated the spatiotemporal patterns of predation risk on black grouse nests using artificial nests that were monitored by camera traps in mountain areas with a small extant (Ore Mts.) and already extinct (Jeseníky Mts.) black grouse population. The overall predation rate of artificial nests was 56% and we found significant differences in survival rate courses over time between both study areas (68% Ore Mts. vs. 41%, Jeseníky Mts.). Within the time required for successful egg incubation (25 days), nest survival probability was 0.32 in the Ore Mts. and 0.59 in Jeseníky Mts. The stone marten (Martes foina) was the primary nest predator in both study areas (39% in total), followed by common raven (Corvus corax, 25%) and red fox (Vulpes vulpes, 22%). The proportion of depredated nests did not differ between habitat types (i.e., open forest interior, clearing, forest edge), but we recorded the effect of interaction of study area and habitat. In Ore Mts., the main nest predator was common raven with seven records (37%). The Eurasian jay (Garrulus glandarius) was responsible for most predation attempts in Jeseníky Mts. (five records, i.e., 83%), while in the Ore Mts., most predation attempts were done by red fox (six records, i.e., 38%).
