Unraveling climatic effects on growth of oak -Europe's most ecologically and economically important forest species -has been the subject of many recent studies; however, more insight based on field data is necessary to better understand the relationship between climate and tree growth and to adapt forest management strategies to future climate change. In this report, we explore the influence of temperature, precipitation and drought variability on the productivity and vitality of oak stands in the Czech Highlands. We collected 180 cores from mature oaks (Quercus petraea) at four forest stands in the Czech Drahany Highlands. Standard dendro-methods were used for sample preparation, ring width measurements, cross-dating, chronology development, and the assessment of growth-climate response patterns. Crown vitality was also evaluated, using the modified ICP Forests methodology. Late spring precipitation totals between May and June as well as the mean July temperature for the year of ring formation were found to be the most important factors for oak growth, whereas crown condition was significantly affected by spring and summer drought. This study is representative for similar bio-ecological habitats across Central Europe and can serve as a dendroclimatological blueprint for earlier periods for which detailed meteorological information is missing.

“…This is particularly important for forest management on summits of the Central European mountains that are "islands" of boreal conditions within temperate landscapes. In the Czech Republic, these mountain conditions of Norway spruce and dwarf pine forest vegetation zones -the 8 th and 9 th in the Czech forest site classification system (Viewegh et al 2003), are the harshest forested sites together with specific conditions of frost pockets regarding the frequency of minimum temperatures, snow cover duration and cold air retention on the site. To restore a needed species composition, coniferous canopy can mitigate partially the impact of frost events occurring over the growing season.…”

It is Norway spruce on acidic Spodosols (Piceetum acidophilum) according to the Czech forest site classification system (Viewegh et al 2003); potential natural vegetation is Calamagrostio villosae-Piceetum (Neuhäuslová et al 1997). In addition to Norway spruce, individually mixed tree species such as European beech, silver fir and rowan share the natural species composition (ÚHÚL 1999).…”

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.

Thinning in artificially regenerated young beech stands

Although beech stands are usually regenerated naturally, an area of up to 5,000 ha year -1 is artificially regenerated by beech in the Czech Republic annually. Unfortunately, these stands often showed insufficient stand density and, consequently, lower quality of stems. Therefore, thinning methods developed for naturally regenerated beech stands are applicable with difficulties. The paper evaluates the data from two thinning experiments established in young artificially regenerated beech stands located in different growing conditions. In both experiments, thinning resulted in the lower amount of salvage cut in following years. Positive effect of thinning on periodic stand basal area increment and on periodic diameter increment of dominant trees was found in the beech stand located at middle elevations. On the other hand, thinning effects in mountain conditions were negligible. Thinning focusing on future stand quality cannot be commonly applied in artificially regenerated beech stands because of their worse initial quality and lower density. However, these stands show good growth and response to thinning, hence their management can be focused on maximising beech wood production.Key words: diameter growth; basal area; Fagus sylvatica; quantity of production abstrakt Ačkoliv jsou bukové porosty obnovovány obvykle přirozeně, v České republice vzniká ročně až 5 tisíc hektarů bukových porostů obnovených uměle. Tyto porosty mají často bohužel nedostatečnou hustotu a v souvislosti s tím i nízkou kvalitu kmenů. Proto je v nich obtížné aplikovat metody výchovy vyvinuté pro porosty obnovené přirozeně. Studie je zaměřena na vyhodnocení dat z dvou experimentů s výchovou založených v mladých uměle obnovených bukových porostech v rozdílných růstových podmínkách. Provedené výchovné zásahy vedly na obou experimentech ke snížení nahodilé těžby v následujících letech. Pozitivní vliv výchovy na periodický přírůst porostní výčetní základny a na periodický tloušťkový přírůst dominantních stromů byl zjištěn ve sledovaných bukových porostech ve středních polohách. Vliv výchovy v horských podmínkách byl nejednoznačný. Kvůli nedostatečné hustotě a kvalitě je obtížné v uměle obnovovaných bukových porostech aplikovat tradiční výchovné zásahy zaměřené na podporu budoucí kvality produkce. Tyto porosty však vykazují dobrý růst a reakci na výchovné zásahy, a proto v nich může být hospodaření zaměřeno na kvantitu produkce bukového dřeva.
