Changes of Climate Characteristics of Forest Altitudinal Zones within the Czech Republic and their Possible Consequences for Forest Species Composition
Abstract
Forest altitudinal zones are important ecological units of forest classification in the Czech Republic. The aim of the study present was to evaluate the changes of climate characteristics of forest altitudinal zones (FAZ) for climatic seasons of 1961-1990 and 1991-2014 in the Czech Republic. Based on these changes, the risks within forestry are identified and it is evaluated whether the current concept of FAZ is still applicable to the differentiation of forest management in the conditions of climate change. The most important changes from the perspective of growth conditions occurred after 1990 in the 1st to 3rd FAZs, where temperatures increased significantly, spring precipitation decreased, and the number of tropical days and the days of reduced water availability in the soil both increased. The detected changes of climate parameters of forest altitudinal zones are an important factor affecting their use in the forestry planning framework.
