“…The pollution load, particularly of sulfur, was reduced tremendously, however, the acid deposition in coniferous stands in the Ore Mts. still plays an important role, particularly due to nitrate deposition, which is currently exceeding critical load in 87 -90 % [28]. We suppose that the full recovery of Norway spruce forest in the Ore Mountains will not occur in the nearest future due to persisting adverse soil conditions.…”

Abstract:The Ore Mountains are an example of the region that suffered from severe environmental pollution caused by long-term coal mining and heavy industry leading to massive dieback of the local Norway spruce forests between the 1970's and 1990's. The situation became getting better at the end of 1990's after pollution loads significantly decreased. In 1998 and 2013, airborne hyperspectral data (with sensor ASAS and APEX, respectively) were used to study recovery of the originally damaged forest stands and compared them with those that have been less affected by environmental pollution. The field campaign (needle biochemical analysis, tree defoliation etc.) accompanied hyperspectral imagery acquisition. An analysis was conducted assessing a set of 16 vegetation indices providing complex information on foliage, biochemistry and canopy biophysics and structure. Five of them (NDVI, NDVI 705 , VOG 1 , MSR and TCARI/OSAVI) showing the best results were employed to study spatial gradients as well as temporal changes. The detected gradients are in accordance with ground truth data on representative trees. The obtained results indicate that the original significant differences between the damaged and undamaged stands have been generally levelled until 2013, although it is still possible to detect signs of the previous damages in several cases.

“…This type of damage affected about 8,000 ha of forest stands Lomský, Šrámek 2004 Podrázský 2006;Šrámek et al 2006). The ameliorative methods including biological and chemical amelioration and reduced air pollution pressure have contributed to stand regeneration and enabled the transformation of existing transitory stands into stands composed of the target tree species (Slodičák et al 2008;Šrámek et al 2008b).…”

Since 1994, the nutritional status and the air pollution load have been evaluated on 20 research plots, located in young Norway spruce stands in the ridge area of the Krušné hory Mts. The most recent acute damage to the spruce stands, in the winter of 1995/96, was connected with a long-lasting inversion situation in the eastern area of the Krušné hory Mts. Today, the health status of the spruce stands, expressed in terms of the crown defoliation, has recovered and is comparable to that found in other regions of the Czech Republic. The sulphur and fluorine content of the needles has decreased significantly. The long-term negative effect of acid deposition that contributes to the degradation of forest soils remains an important part of stressors acting on forest ecosystems in the region. In recent years, nitrogen and sulphur concentrations in the needles have increased slightly again. A long-term tendency towards a decrease in the phosphorus, calcium and potassium content of the needles was detected.

“…and in the Jizerské hory Mts. However, it was found to be an unsuitable tree species in the mountain conditions due to suffering from a site-based decline (Bäucker, Eisenhauer 2001;Šrámek et al 2008). Then the forestry research focused also on Carpathian birch (Betula carpatica Waldstein & Kitaibel ex Willdenow) and white birch (Betula pubescens Ehrhart) that are native pioneer tree species on mountain sites; they can grow also near the tree line.…”

ABSTRACT:Reduced air pollution load has allowed to use commercially oriented forestry in the Central European mountains since the 1990s. The goal is, however, to restore species-and age-diversified stable stands that are expected to cope with uncertain changes of the harsh mountain climate. The microclimate of current young forest stands can impact on growth and performance of underplanted seedlings. In the present study, aboveground (+10 cm), surface (0 cm) and belowground (-10 cm) temperatures were compared under Norway spruce and Carpathian birch canopies. Measurements were performed in 22-year-old Norway spruce and Carpathian birch stands and replicated three times. These measurements were compared with three adjacent gaps dominated by herbal vegetation. Temperatures were measured automatically during the growing periods 2011 and 2012. The research was conducted on Norway spruce on an acidic Spodosol forest site in the summit part of the Jizerské hory Mts., Czech Republic. Data were analysed using the Horn procedure of pivot measures. The highest variability of aboveground and soil surface temperatures was observed within the gaps during a spring time. The temperatures beneath the leafless birch were close to those within the gaps, whereas in the period of leaved trees the temperature extremes were reduced similarly like under the spruce stand canopy compared to the gaps. The differences between the plots were the smallest at the end of growing seasons.
