How does the German forest look like for visitors from the north? There are taller trees and the exotic European beech, but the Norway spruce reminds us of home. We exchanged that and some other thoughts with a delegation from the Finnish Ministry of Agriculture and Forestry who visited the Bonn Office on the 29th of August. They were hosted by colleagues from the German Federal Ministry of Food and Agriculture (BMEL) who also participated in a field visit to an urban forest in Bonn.
After a brief introduction about the EFI Resilience Programme, we had the opportunity to visit the Jägerhäuschen Marteloscope site, where Uwe Schölmerich, the head of the Regional Forest Enterprise Rhein-Sieg-Erft, kindly guided us.
Despite the obvious differences between German and Finnish forest ecology and management, many of the challenges we face are similar. Bark beetles have been causing damages in both countries for a long time, and the exceptionally hot and dry summer brought forest fires to the agenda in an entirely new way. Halting the loss of biodiversity is also an important part of current forest management and planning even if the systems are different.
Forest managers and other interested groups learn about integrated forest management in both countries. The use of demonstration sites such as e.g. Marteloscopes has proven a valuable tool for educating and creating a dialogue among various interest groups relating to different aspects of forest management. The Finnish delegation at the Jägerhäuschen Marteloscope clearly recognized it. They suggested adding a carbon sequestration component to the I+ software training tool which allows to visualize, how forest management decisions affect the carbon balance of the site and how wood products from harvested wood contribute to store carbon over many years. We thanked the Finnish delegation for this valuable input and expressed our hope that Marteloscopes may also find application in training and education in Finland in the near future.

Die Entscheidung zu treffen, welcher Baum als Zukunftsbaum im Wald belassen wird und wachsen darf, und welcher Baum entnommen wird, ist nicht immer einfach. Schließlich spielen neben ökonomischen Parametern wie der Holzqualität und der Wuchsform auch ökologische Parameter, so genannte Mikrohabitate, wie beispielsweise tote Äste und Rindentaschen, bei der Entscheidung eine wichtige Rolle.
Um nachhaltige Forstwirtschaft und Naturschutz sinnvoll und anschaulich miteinander verbinden zu können, ist am 4. Juli 2018 das erste rheinland-pfälzische Marteloskop „Viergemeindewald“ eröffnet worden. Auf einer ca. 1 ha großen Waldfläche sind hier alle Bäume ab einem Brusthöhendurchmesser von 7 Zentimetern erfasst, vermessen und fortlaufend nummeriert. Zusätzlich sind für jeden Baum die ökonomischen sowie ökologischen Parameter aufgenommen.
Forstfachleute aus acht Bundesländern und aus der Schweiz tauschten sich zu den Perspektiven von IT-gestützten Waldbau-Schulungen aus.
Vom 10.-11.7.2018 trafen sich in Bonn forstliche Fachleute aus zahlreichen Bundesländern, aus der Schweiz und von Hochschulen sowie vom Europäischen Forstinstitut (EFI), um sich zum Stand und zu Perspektiven von Waldbau-Schulungen auszutauschen. Hierbei ging es vor allem um die künftige Rolle moderner Informationstechnologien und um die didaktische Weiterentwicklung von Waldbau-Schulungen. Präsentiert und diskutiert wurden Erfahrungen aus dem von EFI initiierten Integrate+-Projekt (Integration von Waldnaturschutz in die Waldbewirtschaftung und Nutzung besonderer Demonstrationsflächen) und aus den Forstverwaltungen verschiedener Bundesländer. Das Expertentreffen begann mit dem Austausch von Erfahrungen bezüglich der Nutzung von Demonstrationsflächen für die integrative Waldbewirtschaftung, sogenannte Marteloskopflächen, für unterschiedliche Trainingszwecke. Darüber hinaus wurden Beispiele aus der Praxis des Waldbau-Trainings vorgestellt und Entwicklungsperspektiven für die Waldbau-Schulung diskutiert. In Bonn sind die ersten beiden NRW-Marteloskope nach dem Integrate+-Ansatz eingerichtet. Eine dieser Flächen im Kottenforst wurde unter Führung von Uwe Schölmerich und Klaus Striepen von Wald und Holz NRW am zweiten Tag besucht, um den Erfahrungsaustausch im Wald fortzusetzen. Die Exkursion war auch verbunden mit einer virtuellen, von einer am EFI entwickelten Trainingssoftware unterstützten Durchforstungsübung.

The Steigerwald, one of Germany’s largest deciduous forest, was almost in summer attire when a group of forest experts from 12 different countries met for a workshop, organized by Andreas Schuck and Jakob Derks from the European Forest Institute and Daniel Kraus from the Bavarian State Forest Enterprise. No less than 45 participants gathered to exchange experiences related to the use of Marteloscopes in the Ebrach forest district. The group was composed of forest and nature conservation managers, forest administration and ministry representatives as well as scientists from different disciplines. Norbert Vollmann from the newspaper Mainpost wrote an article in German about the workshop.
The network of marteloscopes, which was started during the Integrate+ project, is continuously expanding in terms of sites and users. On April 12th, Andreas Schuck from European Forest Institute led a marteloscope exercise in the Jägerhäuschen marteloscope in Kottenforst near Bonn, assisted by me. The training session was organised in cooperation with the local forest district Rhein-Sieg-Erft. Most of the twelve participants work for the BfN, the German Federal Agency for Nature Conservation, but there were also two representatives of the German Federal Ministry of Food and Agriculture.
Foresters exploring the Rosskopf Marteloscope in cooperation with ConFoBi researchers

ConFoBi (Conservation of Forest Biodiversity in Multiple-Use Landscapes of Central Europe) is a research project of the University of Freiburg and the Forest Research Institute Baden-Württemberg (FVA) that focuses on the effectiveness of structural retention measures for biodiversity conservation in multi-functional forests. Researchers work in a common pool of 135 study plots located in the Black Forest. In the course of ConFoBi’s yearly information event for foresters managing those forest areas that contain one of the 135 plots, a Marteloscope training exercise was conducted with 10 foresters from Forst-BW.
Frank Krumm (Swiss Federal Institute for Forest, Snow and Landscape Research WSL) and Andreas Schuck (European Forest Institute) introduced the Marteloscope concept as a training tool for thinning exercises revealing common challenges and trade-offs in integrative forest management. Marteloscopes are one hectare forest sites where all trees have been numbered, mapped and measured. With the help of the “I+”software that runs on mobile devices, trees can be virtually harvested and retained. Thereby the results of the individual tree selection, namely the ecological and economic consequences, can be immediately displayed, initiating discussions as well as learning processes.
Representatives from nature conservation organisations, LIFE+ projects, state forest enterprises and forest associations (communal and private forest owners) situated in North Rhine Westphalia visited the Marteloscope Jägerhäuschen. The Marteloscope is located in the Kottenforst area at the Regional Forest District Office Rhein-Sieg-Erft just outside the City of Bonn.
A Marteloscope training exercise took place on the 25th of October 2017 in the Sihlwald Marteloscope in Switzerland which is managed by the Wildnispark Zürich.
The course was organised for 20 students from the Bern University of Applied Sciences – School of Agricultural, Forest and Food Sciences (HAFL). A central aim set by Thibault Lachat (HAFL), Andreas Schuck (EFI) and Frank Krumm (WSL) was to ensure that students learn to make educated decisions by taking into account numerous aspects when managing forest stands. In particular, the workshop focused on how to ensure maintaining biological diversity in managed forests – and dealt with the question of what the gains are and where to make the trade-offs .
Marteloscope sites are like outdoor forest classrooms where the trees are numbered, mapped and measured. They can be used to train foresters and other interest groups how different silvicultural measures may affect forest biodiversity and to what extent. Software running on mobile devices allows virtual tree selection exercises and then displays the results. Participants can immediately see the ecological and economic consequences of their choices. Variations in exercise results initiate discussion and stimulate the exchange of experiences and learning.
Andreas Schuck from the EFI Bonn team is conducting training exercises with different stakeholders from the field of forestry, nature conservation, and academia. The latest training took place at the Falkenberg Marteloscope on 16th of October. It is located in the northern Vosges region of France. Twelve participants representing both forestry and nature conservation were introduced to Marteloscopes and their potential applications followed by a virtual tree selection exercise. The exercise asked for selecting habitat trees while removing high quality trees for economic return. Andreas Schuck and Frank Krumm from the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) moderated the training jointly with Loïc Duchamp from the Parc Naturel Régional des Vosges du Nord, France (PNRVN). The same virtual tree selection exercise was implemented by groups of two followed by a brief presentation of results and joint discussion. Habitat and economic valuable trees were then looked at more closely in order to challenge the groups on their decisions.
Utilising our forests with care and understanding will ensure that they continue to deliver everything we value now and for generations to come. Wood is a much needed resource and will continue to be in future. The film wise use of our forests: the integrative approach aims at presenting Europe’s forest in this context.
