Název v původním jazyce

Monitoring of alluvial soils in the Southern Moravian region of the Czech Republic

Popis výsledku v původním jazyce

The largest complex of floodplain forests in the Czech Republic is situated along the confluence of the rivers Morava and Dyje/Thaya. The studied locality is located in an area close to the Czech-Austrian-Slovakian border. Natural conditions, which affected the natural floodplain ecosystem for a long time, were markedly disturbed by man in the &apos;70s of the 20th century. After extensive water-management measures, both rivers including their local tributaries were channelised and diked. Formerly regularly repeating short-term floods were eliminated and as a result, the groundwater level decreased. However, its important annual dynamics have been preserved. The impaired water balance resulted in the local die-back of mature forest stands of the floodplain forest during a climatic dry spell. Monitoring takes place at the right and left banks of the Dyje river. The right bank of the Dyje river is covered by wetland meadows and the area takes approximately 231.87 ha. It is also an important protected catchment of drinking water for municipals. Stress factors like land use changes, riverbed regulations, and changes in temperature and humidity conditions directly affect the ecosystem stability. On the other hand, revitalization efforts, transboundary river management, wetland restoration, and integrated planning are undertaken to mitigate the negative effects and groundwater decline. Therefore, continuous monitoring and data set collecting are important, especially with the designation of National Nature Reserve Podyjí. This study aims to track changes in groundwater level, soil hydrophysical properties, and forest vitality during the period of 2019-2023. The results were assessed using z-scores, means, and standard deviations. Monthly evaluations of soil and climatic conditions revealed that irregular rainfall patterns and rising temperatures have a significant impact on the soil&apos;s hydrological regime and forest growth. Ongoing monitoring is important for developing projection models that can provide a better understanding of changes in both soil properties and tree growth parameters.
