Um über die Waldarbeiten im Bonner Stadtwald aufzuklären, die vielerorts erst einmal auf Unverständnis stoßen, lud das Amt für Stadtgrün der Stadt Bonn für den Nachmittag des 19. Februar 2019 zu einem Waldspaziergang ein. Stadtförster Sebastian Korintenberg gab den interessierten Bonner BürgerInnen Einblicke in die derzeit durchgeführten Holzerntearbeiten und sprach über die Folgen des Borkenkäferbefalls.
Who does’t know the adventures of Asterix and Obelix? These two friends and their fellow villagers are constantly trying to defend their way of life against the never-ending attempts from outsiders to destroy it. Stories like this have occurred throughout history all across the planet, but luckily most of them are peaceful. This is a story about resilience; not only of forests, but mainly of people.
No, not the border fence between Ireland and Northern Ireland, no.
In this blog, we are discussing tree species composition, forest adaptation and conversion towards more resilient forests! Deer management in silviculture is one of the crucial factors to consider, just like enough light for the seedlings and site conditions. And here are the fencing news from Ireland, I quote from the Irish newspaper “Independant”.
“New deer fencing grant among measures to support biodiversity of Irish forests: Minister of State at the Department of Agriculture, Andrew Doyle today announced the opening of three new support measures to support biodiversity of Irish forests. A new scheme to support ‘Continuous Cover Forestry’, (CCF), which allows for the production of commercial timber while retaining forest cover at all times. Continuous Cover Forestry (CCF) is an alternative forest management approach where the forest canopy is maintained at one or more levels without clearfelling. The distinctive element of CCF is the avoidance of clearfelling areas greater than 0.25 ha or more than two tree heights wide without the retention of some mature trees. These systems are generally associated with natural regeneration but natural regeneration can be supplemented by planting if required.
Slovakia, as a member of the Network INTEGRATE, established two new Martelescope sites at the end of the year 2018.

The sites are located very close to Bratislava city, at a specific locality with the name „Devínska kobyla” in the Little Carpathian Mountains. The area is managed by the forest state enterprise LESY Slovenskej republiky, branch Smolenice. Forest managers selected two types of stands: predominantly beech and oak. The two sites are only a few kilometres away from each other, at an altitude of 300 m and 340 m above sea level. Both forests are more than 100 years old. Experts from our National Forest Centre in Zvolen realized measuring of all trees on a rectangular square of 100x100m. Consequently, they identified microhabitats on all trees according to the reference field list, which is part of the tree microhabitats catalogue developed by the European Forest Institute (Kraus et al. 2016). The total number of trees was 203 in the beech plot and 409 in the oak plot.
Simon Poljanšek, you are the new Slovenian national focal point for the European Network INTEGRATE. Would you please introduce yourself?
Growing up on a small farm, surrounded by forest and animals, it was easy for me to connect with nature and outdoor activities, road cycling, photography, animals, and becoming a family man. An obvious choice was to study at the University of Ljubljana Biotechnical Faculty, Department for Forestry and Renewable Forest Resources. I successfully finished my studies there with a rewarded diploma thesis on the analysis of the amount and structure of deadwood in Slovenian forests. My education continued with a doctoral thesis on dendrochronological investigation of Black pine (Pinus nigra Arnold) in the Balkan Peninsula, which I conducted at the Slovenian Forestry Institute. I used different tree-ring parameters (widths, density and stable isotopes) to investigate the influence of climate (temperature, sunshine, precipitation, river hydrology) or other extreme events (forest fires) on trees, growing in various environments from mountainous sites to urban surroundings. What are you currently working on in the Slovenian Ministry of Agriculture, Forestry and Food?
The knowledge obtained on this path I described above is now used for monitoring contents and procedures of forest management plans, and assessing forest resources. Furthermore, I use my scientific experience to review targeted research projects, and to collaborate with my team in the development of the “LULUCF” national forestry accounting plan. Finally, a crucial part of my work is to cooperate in different governmental and other institutional associations with the aim of developing system solutions for the sustainable development of forests ecosystems, resilience and biodiversity, alongside with environmental, production and social forests functions.

The network of I+ marteloscopes is in constant expansion. While the epicenter is still located in Central Europe, more and more demonstration sites are being installed in notably the Southeast and the Southwest of our continent. Exemplary for the latter category is the relatively new Hèches marteloscope, located at the foot of the central Pyrenees in southern France. Le réseau des marteloscopes I+ est en constante expansion. Alors que l’épicentre est toujours situé en Europe centrale, de plus en plus de sites de démonstration sont installés notamment dans le sud-est et le sud-ouest de notre continent. Le marteloscope d’Hèches, relativement récent, situé au pied des Pyrénées centrales, dans le sud de la France, est exemplaire pour cette dernière catégorie. (pour la version française : vers le bas)

In the beautiful autumn forest in Vosges du Nord – Forêt de Bitche, France, we organized a training session with 44 foresters from public and private forests on 18th and 19th of October 2018. The Marteloscope ‘Falkenberg’ was set up in the course of European Forest Institute’s Integrate+ project, and it is located on state forest land in a Nature Reserve, in the heart of the Northern Vosges Regional Nature Park (French part of the Transboundary Biosphere Reserve Vosges du Nord–Pfälzerwald). 60%, or 76.283 ha of the park are covered by forest, composed of 58% broadleaves and 42% conifers.
One main conservation objective in that nature reserve is to increase forest naturalness. This is achieved by designating strictly protected areas and preserving or restoring forest composition and potential habitats in managed forests.
Das Thema Waldnaturschutz spaltet Waldschützer und Waldnutzer. Dabei sollten gerade diese an einem Strang ziehen und im Interesse der Waldökologie zusammenarbeiten. Es reicht nicht aus, 5% der Waldfläche Deutschlands aus der Nutzung zu nehmen. Schutzmaßnahmen für unsere Waldarten müssen auch auf den restlichen 95% gewährleistet werden. Das sogenannte ‘Trittsteinkonzept’ ist dafür ein guter Weg – und die Elemente des Konzepts lassen sich in allen Wäldern umsetzen.

The Annual Pro Silva Ireland forestry tour 2018 was heading towards Obernai, France where the French National Forest Office’s (ONF) silviculture trainer Marc-Etienne Wilhelm hosted the “Irish forestry invasion” for 3 days. A total of 27 members of Pro Silva Ireland participated in the tour, indicating the strength of interest in continuous cover forestry (CCF) among Irish foresters, forest ecologists and woodland owners at the present time.
As a participant in the tour, I (Ted Wilson) took the opportunity to extend my travels and visit the Martelscope training sites at Mooswaldand Rosskopf, near Freiburg, Black Forest, Germany. My work is based at the Teagasc Forestry Development Department, Ashtown Research Centre, and at the School of Agriculture and Food Science (Forestry Section), University College Dublin, both in Dublin, Ireland. My current research focuses on CCF, and my main project is called TranSSFor. This deals with the transformation of Sitka spruce plantations to continuous cover forestry. Related to silvicultural and production objectives of the research project is the issue of training, which was the focus of a highly productive meeting with Alex Held and Andreas Schuck, who are with the European Forest Institute.
