Die Einführung von Baumarten ist ein bedeutendes und zugleich kontroverses Thema. In allen Ländern Europas sind eingeführte Arten einerseits als Chance für die Steigerung der Holzproduktion gesehen und können Alternativen für eine sich unter dem Einfluss des Klimawandels verändernde Artenzusammensetzung in Wäldern darstellen. Andererseits können eingeführte Arten auch die Ursache für den Verlust an Artenvielfalt sein, natürliche Ökosysteme stören und bei ungewünschter Verbreitung hohe Kosten verursachen.
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.
We are happy to share that our network of Marteloscopes is continuously expanding both in terms of number of sites and countries. New countries joining the Integrate Marteloscopes network are Luxembourg, Romania, Serbia, Slovakia and Spain. They are currently either in the process of setting up sites or have indicated to establish them in the coming months. Countries already having established Marteloscopes are adding additional ones as e.g. the Czech Republic, France, Germany (also increasing the coverage across Federal States), Poland and Switzerland. All in all we can look forward to increasing the total number of Marteloscopes by at least 25 new sites (adding to a total of then around 65) in the course of 2019.
Not only is the their number growing but also their application. Many events were implemented by different ‘Marteloscope managers’ during the second half of 2018. They varied from Marteloscope visits during field excursions to tailored training schools. In particular the value for silviculture training has gained momentum and goes as far as investigating options of embedding Marteloscopes in training curricula. The range of topics also does not stop at nature conservation aspects in managed forests but addresses also other aspects (such as silvicultural treatments and climate change impacts). We also continue to collect feedback from our network on what further applications are seen for Marteloscopes and the corresponding I+ software. Examples are exporting exercise results to growth simulators and adding new training modules to the software including topics such as climate change and carbon sequestration.
A recent development is the interest of pedagogic universities in Marteloscopes. They see good potential in using them within school education programmes. Concluding, we would like to draw attention to our ‘I+’ software store webpage. It serves as access point to downloading the ‘I+’ software components, provides software tutorials, contact details to established Marteloscope sites and a range of supporting documents.
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.
by Eva Hušťáková
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.
