Název v původním jazyce

Patterns of spring soil moisture regimes under the canopy of beech, spruce and larch trees

Popis výsledku v původním jazyce

Presented contribution follows the results of established soil moisture and temperature monitoring of Czech University of Life Sciences located at experimental site Amálie. It further broadens the insights into climate-change adaptation management of droughtprone forested areas, considering different effects of deciduous and evergreen species on landscape water management. The findings revealed substantial differences in soil moisture regimes between deciduous (beech – Fagus sylvatica, larch – Larix decidua) and evergreen (spruce – Picea abies) species (Kuželková et al., 2024). These differences are most pronounced during the spring months due to the canopy interception and early transpiration of evergreen spruce. In contrast, the interception and transpiration losses of deciduous trees are significantly reduced until foliage emergence in early May. From March to May, the soil moisture under spruce repeatedly drops below the limit of easily available water, while beech and larch retain significantly higher soil moisture levels, keeping the soil water resource for the warmest months. The repeating spring patterns of depleted soil moisture under the canopy of evergreen spruce, suggests the importance of respecting the species-specific adaptation to lower altitudes with limited precipitation and increased temperatures. With the actual rise in extreme meteorological events due to climate changes, the prioritizing of native habitat– adapted species over the abundant mountain–adapted species like spruce is becoming highly relevant.
