    Aktiv Totholz schaffen? Das Projekt Hochstümpfe in Bayern (2020) AFZ-DerWald 2020 (21), S. 29-33.

    Mit einem neuen Naturschutzprojekt produzieren die Bayerischen Staatsforsten seit 2018 aktiv stehendes Totholz. Unter dem Sonderprogramm „Der Wald blüht auf“ entstanden bayernweit rund 5.000 Hochstümpfe – eine Literaturstudie zum Forschungsprojekt „Hochstümpfe in Bayern“.

    Nadelbäume im Trockenstress (2020) LWF aktuell 3/2020 (126), S. 24-27.

    Artverbreitung, Wachstum, Überlebenswahrscheinlichkeit, Jahrringsensitivität – in den vergangenen Jahren wurden an der LWF zu all diesen Vitalitätseigenschaften von Baumarten verschiedene Modelle entwickelt, um der forstlichen Praxis eine Hilfestellung zur Einschätzung der Baumarteneignung im Klimawandel zu geben. In dieser Studie vereinen wir diese Modelle in einem multikriteriellen Baumartenbewertungskonzept, um die Trockenheitsresistenz wichtiger Nadelbaumarten in Mitteleuropa abzuschätzen.

    Half a century of Scots pine forest ecosystem monitoring reveals long‐term effects of atmospheric deposition and climate change (2020) Global Change Biology . DOI: 10.1111/gcb.15265

    At two forest sites in Germany (Pfaffenwinkel , Pustert ) stocked with mature Scots pine (Pinus sylvestris L.), we investigated changes of topsoil chemistry during the recent 40 years by soil inventories conducted on replicated control plots of fertilization experiments, allowing a statistical analysis. Additionally, we monitored the nutritional status of both stands from 1964 until 2019 and quantified stand growth during the monitoring period by repeated stand inventories. Moreover, we monitored climate variables (air temperature and precipitation) and calculated annual climatic water balances from 1991 to 2019. Atmospheric nitrogen (N) and sulfur (S) deposition between 1964 and 2019 was estimated for the period 1969–2019 by combining annual deposition measurements conducted in 1985–1987 and 2004 with long‐term deposition records from long‐term forest monitoring stations. We investigated interrelations between topsoil chemistry, stand nutrition, stand growth, deposition, and climate trends. At both sites, the onset of the new millennium was a turning point of important biogeochemical processes. Topsoil acidification turned into re‐alkalinization, soil organic matter (SOM) accumulation stopped, and likely turned into SOM depletion. In the new millennium, topsoil stocks of S and plant‐available phosphorus (P) as well as S and P concentrations in Scots pine foliage decreased substantially; yet, age‐referenced stand growth remained at levels far above those expected from yield table data. Tree P and S nutrition as well as climate change (increased temperature and drought stress) have replaced soil acidification as major future challenges for both forests. Understanding of P and S cycling and water fluxes in forest ecosystems, and consideration of these issues in forest management is important for successfully tackling the new challenges. Our study illustrates the importance of long‐term forest monitoring to identify slow, but substantial changes of forest biogeochemistry driven by natural and anthropogenic global change.

    Plant indicators for Folic Histosols in mountain forests of the Calcareous Alps (2019) Applied Vegetation Science 23 (2), S. 285-296. DOI: 10.1111/avsc.12470

    Questions: Although thick forest floors overlying unweathered bedrock are important resources for mountain forests' functioning, their actual distribution is poorly known and difficult to delimit in the field. We therefore asked: (a) What is the specific composition of vegetation growing on Folic Histosols; (b) can indicator plants be used to detect Folic Histosols in mountain forests; (c) what do functional traits of plant indicators tell about the ecological properties of Folic Histosols? Location: Northern Calcareous Alps, south Germany. Methods: Based on representative stratified sampling of joint vegetation plots and soil profile descriptions, we estimated the frequency and thickness of Folic Histosols, determined the proportion of compositional variation specifically attributable to forest floor thickness using ordination, applied Indicator Species Analysis and searched for typical traits and ecological requirements of indicator species. Results: The co-existence of acidophilic and calciphytic plants is typical for the tessellated occurrence and the successional origin of Folic Histosols. In the study region, the detection of Folic Histosols on pure limestone or dolomite by ground vegetation works very well. Particularly acidophilic plants are suitable indicators for thick forest floors. The indicator value of bryophytes and Ericaceae for Folic Histosols is likely related to the colonization of rotten wood. Folic Histosol indicator species are widely spread in the allocation to sociology group, which ranges from open landscapes to dark forests and reflects successional origin. Conclusions: In mountain forests on carbonate bedrock, thick humus layers often occur next to bare rock. This tessellated structure can also be detected in the ground vegetation, where acidophilic and calciphytic plants occur side by side. Thick Folic Histosols in late successional forests are dominated by acidophilic plants colonizing rotten wood. Thus, the detection of Folic Histosols by understorey species is an easy and cost-effective possibility and one key to protect these vulnerable forest sites.
