This article presents guidelines for assessing the optimal dimensions of forest road pipe culverts, based on input of actual and experimental data to standard engineering techniques. In doing so, we assess the need for (i) changes in the parametrisation of inputs (i.e. culvert micro-catchment dimensions, rainfall and resultant culvert flow, and culvert flow rates during culvert hydraulic dimensioning), and (ii) the need to redesign culvert outlets in relation to flow speed. Our results demonstrate that values for most inputs presently used under current technical practice for forest road pipe culvert sizing are significantly higher than...

Global climate change (GCC) is putting increasing pressure on forest ecosystems, leading to more frequent disturbances such as pest outbreaks and other climate-related stressors, all of which threaten forest stability. This study examines how different technical water retention measures (infiltration pits) can enhance the resilience of European beech (Fagus sylvatica L.) to these climatic challenges, focusing on their impact on radial growth, sap flow, and acclimatisation to moisture conditions at two sites in Czechia (430–440 m a.s.l.). Three treatments were compared: a water infiltration pit under a culvert mouth, an infiltration...

An unprecedented bark beetle outbreak has led to a significant decline in forest cover in Central Europe in the last 10 years, affecting an area estimated at more than 200 000 ha in the Czech Republic. Among the many ecological threats associated with extensive clearings, the potential alteration of hydrological processes is one of the most important. Therefore, after 2022, the precipitation–runoff balance in three catchments in the Jeseníky Mts. area was studied. This study focuses on the rainfall variability within the area, which was measured using 24 rain gauges deployed to cover different altitudes as well as the geographical exposures...
Carbon storage and climate mitigation effect in Central European forestry – To be managed, or left unmanaged?Original Paper

This study investigates differences in carbon storage between managed and unmanaged forests in the growth conditions of Central Europe. Norway spruce (Picea abies), European beech (Fagus sylvatica) and pedunculate oak (Quercus robur) dominated forest types were considered, as these are the most common forest species in the Czech Republic. Scots pine (Pinus sylvestris), as the second most common species, was excluded due to lacking relevant reference data on unmanaged forests. Managed and unmanaged variants of each forest type were assessed in terms of carbon sequestered in biomass, dead wood and harvested wood products (in...
