The aim of this paper is to analyze change of the ecological conditions of forest vegetation zones of Krivánska Fatra Mts and evaluate the response of vegetation to climate change for the period 1974 – 2015. Phytocenological relevés in the vegetation zones of Krivánska Fatra Mts were realized in 1974 and re-entries were realized in the permanent study / stationary areas of the national nature reserves Rozsutec and Chleb between 2014 and 2016. Impact of climate change on vegetation in the past 40 years was assessed using the Ellenberg ecological indices and diversity indexes of the assessed communities. The values of ecological indices computed from 99 phytosociological records done in 1974 in the forest vegetation zones of Krivánska Fatra Mts were compared with nation-wide values of the indices in the same forest vegetation zones. The differences of average values of the ecological indices between 1974 and 2015 were not statistically significant. Also the tree species composition in the repeated phytocenological entries realized the past 45 years, revealed no significant changes. To summarize, ecological analyzes of forest phytocenoses in the forest vegetation zones of Krivánska Fatra Mts did not confirm the theorem of recent climate change impact on the forest vegetation zones of these mountains. This can be explained by the strong buffer effect of the forest cover, esp. by maintaining relatively stable forest microclimate (light, temperature, moisture) under the forest canopy. However, the species composition of forest ecosystems has been partly influenced by acidification and eutrophication of the environment in the second half of the 20th century.

Malá Fatra (Slovensko : pohorie) Jazyk dok. slovenčina Krajina Slovenská republika Systematika 911 Anotácia On the southwestern foot of Malá Fatra Mts is the northernmost locality of the European important oak-beech habitat (Fagetum quercinum Zl. 59, Luzulo-agetum Br.Bl.) in the Slovak Republic. Slope on granite bedrock is 25° to 35° at an altitude of 350-550 m a.s.l. The paper presents an ecological analysis of this community according to Ellenberg ecological numbers of between 1974 and 2014 years. Succession changes over the past 40 years are reflected by a spatial arrangement of tree species. For mineral poor, medium deep to shallow oligotrophic Cambisol in tree species composition dominated by sessile oak (Quercus petraea. Less is represented by beech (Fagus sylvatica, birch (Betula pendula) and pine (Pinus sylvestris. A single occurrence of a solitary pine binds to the top of the granite cliffs where there are no conditions for the application of oak. Spatial composition of trees is the mosaic in small areas (gaps, depending on the depth of the soil and the surface stoniness. In the last 40 years, there has been no significant change of ecological characteristics in the herb layer, which reflects the relative good ecological stability of this European Important Habitat Kategória publikačnej činnosti ADF Číslo archívnej kópie 37415 Katal.org.
