Disturbance Recovery

Abstract Context Recovery from disturbances is a prominent measure of forest ecosystem resilience, with swift recovery indicating resilient systems. The forest ecosystems of Central Europe have recently been affected by unprecedented levels of natural disturbance, yet our understanding of their ability to recover from disturbances is still limited. Objectives We here integrated satellite and airborne Lidar data to (i) quantify multi-decadal post-disturbance recovery of two indicators of forest structure, and (ii) compare the recovery trajectories of forest structure among managed and un-managed forests. Methods We developed satellite-based models predicting Lidar-derived estimates of tree cover and stand height at 30 m grain across a 3100 km2 landscape in the Bohemian Forest Ecosystem (Central Europe). We summarized the percentage of disturbed area that recovered to > 40% tree cover and > 5 m stand height and quantified the variability in both indicators over a 30-year period. The analyses were stratified by three management regimes (managed, protected, strictly protected) and two forest types (beech-dominated, spruce-dominated). Results We found that on average 84% of the disturbed area met our recovery threshold 30 years post-disturbance. The rate of recovery was slower in un-managed compared to managed forests. Variability in tree cover was more persistent over time in un-managed forests, while managed forests strongly converged after a few decades post-disturbance. Conclusion We conclude that current management facilitates the recovery of forest structure in Central European forest ecosystems. However, our results underline that forests recovered well from disturbances also in the absence of human intervention. Our analysis highlights the high resilience of Central European forest ecosystems to recent disturbances.

<p>With the aim to simulate the exchange of energy and matter between air and vegetation, we applied the LES PALM to a typical Central European forest. The presentation shows how the level of detail within vegetation model and the orography alters the simulated flow.</p><p>The site of investigation is a managed mixed forest stand (mainly Picea abies, height 30 m; a long-term CarboEurope monitoring site) within the Tharandter Wald near Dresden, Germany. Terrestrial laser scans (TLS) provided the data basis for the high-resolution vegetation model of this forest stand and a nearby clearing (50x90 m) building the inner range of the model domain. To investigate orographic effects on the flow, we extended the domain for about 1.5 km to the west. This includes the S-Berg, which is about 40 m height and therefore the highest elevation on the windward side. We used information from airborne laser scanning (ALS) along with forest inventory data to build a vegetation model as well as a digital elevation model for the extended area (2 km in streamwise and 1.5 km in lateral direction) with a resolution of (2m)<sup>3</sup>. </p><p>In a first step, we restricted all simulations to a neutral atmosphere to exclude effect of buoyancy.</p><p>Wind data from four measurement towers (from DFG SPP 1276 MetStröm) provided data for a validation of the simulations. They were located within the inner domain along a west-east transect over the clearing.</p>

Trifolium rubens is a Central European forest-steppe plant species reaching its eastern distribution limit in Ukraine and listed in the Red Book of Ukraine (2009).Our study was carried out in 2016–2020 and aimed to analyze the distribution of T. rubens in Ukraine, to identify the composition of phytocoenoses with T. rubens, and to evaluate the current state of its populations in the Zakarpattia region of Ukraine. The distribution of this species was analyzed based on data obtained from the field surveys, literature, online resources, and herbaria. In total, 78 localities of T. rubens were analyzed. Trifolium rubens was found to be distributed in Zakarpattia, Lviv, Ivano-Frankivsk, Ternopil, Rivne, Khmelnytskyi, Chernivtsi, and Vinnytsia regions of Ukraine. Two of these regions (Khmelnytskyi and Chernivtsi) were not mentioned before in the Red Book of Ukraine. The presence of T. rubens in Volyn, Zhytomyr, Cherkasy, and Kyiv regions is doubtful and not confirmed by recent data. Most localities of this species are known from Zakarpattia and Lviv regions.Three new localities were found in the Beregovo district of the Zakarpattia region in the foothills of the Volcanic Carpathians. The floristic compositions of the plant communities and ontogenetic structure of T. rubens populations in Beregovo and Mukachevo districts of the Zakarpattia region were investigated. Investigated populations are isolated with a dispersed disposition of plants on large areas. Trifolium rubens occurs here in meadow-steppe and meadow areas, on hillsides, and also participate in mesoxerophilous secondary (semi-natural) shrub communities in anthropogenically transformed areas. Often such populations are situated along pathways, on forest edges and fallow lands, and associated with ecotones of Trifolio-Geranietea sanguinei class. All studied populations were incomplete with the domination of generative shoots.
