Comparison of Rainfall Partitioning and Estimation of the Utilisation of Available Water in a Monoculture Beech Forest and a Mixed Beech-Oak-Linden Forest

Monoculture forests formed by Fagus sylvatica L. belong to one of the most sensitive forest ecosystems, mainly at low altitudes. Cultivation this species in mixed stands should reduce its sensitivity drought vegetation period, which is why we researched water balance pure-beech (i.e., monoculture) and beech–oak–linden mixed) forest. This research was carried out Drahanská vrchovina Czech Republic period 2019–2021. The total precipitation measured, together with partitions throughfall stemflow), crown interception also calculated. transpiration calculated from values measured on sample trees. each rainfall partition (and their percentages) were compared. monoculture differed those While, average, annual percentages throughfall, stemflow 63%, 6% 31%, respectively, these 76%, 2% 22%, respectively. greater (31% precipitation) effective sum stemflow) (78% precipitation). greatest differences (in partition) between summer winter. (ca. 22% ca. 12% winter), 66% 51% winter). mean 318 (±52) mm 451 (±58) forest, i.e., about 99 (±65) more than transpiration, comparison precipitation, made up, 70% On other hand, reached 71% 2019), 74% 2020) even 100% 2021) Our results show that an oak–beech–linden can manage better a beech because leaked through onto soil monoculture, especially via summer. amount transpired monoculture. However, utilisation trees very similar all three years, while, increased, may have been caused saturation deeper layers first two years measurement. We can, Therefore, say that, lower altitudes, it will be suitable future cultivate assumed lack (mainly early spring summer).
