Voices of Resilience introduces Rupert Seidl, Professor of forest ecosystem management and Deputy Head of the Institute of Silviculture at the University of Natural Resources and Life Sciences (BOKU), Vienna, Austria. His research focuses on understanding how climate and disturbances affect forest ecosystem dynamics, and on applying this knowledge towards increasing the robustness of forest management in a changing world.
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.
In this article, I talk about the “mode of competition”, in other words whether trees of different species compete more of aboveground or belowground resources when growing in mixed stands. Additionally, I highlight the advantage of mixed forests in the context of climate change.
If you have read some of my articles like What factors determine whether tree species compete or complement each other?, you know how much I like mixed forests. Forests rich in tree species not only are known for providing higher levels of ecosystem services but also be prompter to cope with unexpected disturbances and climatic changes. However, the mechanisms of competitions in multi-species forests are all but clear. Scientists are still studying which combinations of tree species grow better in a particular environment or what factor promote or reduce a positive growth complementarity in secondary forests and/or plantations. In one of my latest posts on the blog Forest Monitor I have tried to explain in simple terms the concept of how complementarity for a give species can be positive or negative when growing in association with other species depending on resource availability.

A group of researchers from all over Europe worked together to release a unique database to the scientific community. Assembling data collected under the auspices of an EU Cost Action, the database BeechCOSTe52 gathers over 860,000 measurements of phenotypic traits. These data, from more than 500,000 beech trees growing in plantations located in 38 European countries, cover the entire range of beech’s distribution. Over 15 years of work have gone into producing the database; a vital resource for analyzing and understanding the beech’s adaptive capacity to climate change and the potential effects of climate on its distribution range.
Der Sommer 2018 war und ist immer noch ein ausgesprochener Feuer-Sommer für unsere Wälder in Deutschland und Zentraleuropa. Eine ungewohnt hohe Zahl von Vegetationsbränden zwingt zur Diskussion der Ursachen einerseits, regt aber auch zum Nachdenken an, was zukünftig getan werden kann und muss.
Erste schnelle Reaktionen befassen sich wie üblich sofort mit der Feuerwehr und der Frage, wie die Einsatzkräfte in Zukunft noch besser und effizienter vorgehen können – also der reaktive Ansatz und die Bekämpfung des Symptoms, aber nicht der Ursache. Selbstverständlich brauchen wir Feuerwehren, die bestmöglichst ausgebildet und ausgerüstet sind. Der Blick über unsere Ländergrenzen hinweg bietet zahlreiche Möglichkeiten, hier nachzubessern. Die European Forest Risk Facility und das weitere Netzwerk sind seit langem in diesem Bereich des länderübergreifenden “Exchange of Experts” tätig. Allerdings nicht nur auf reaktiver Seite sondern auch und vorallem in den Bereichen Prävention und Erhöhung der Resilienz.
Since 1995, the Bonn-based German expert for green impact investing ForestFinance has been planting forests in the project countries Panama, Peru, Colombia and Vietnam. Now, the reforestation company has just planted its ten millionth tree.
“In 2009, we planted and celebrated our millionth tree in Panama City in the presence of the Panamanian Minister of Environmental Affairs. Today – nine years later – we have increased this number tenfold. We have achieved this together with over 19,000 customers and environmentally conscious investors,” explains Harry Assenmacher, founder of the ForestFinance Group.
Programms of afforestation to create forests increase carbon capture and carbon sequestration, and help to anthropogenically improve biodiversity.

“We must act to halt and reverse the unsustainable use of nature – or risk not only the future we want, but even the lives we currently lead”, says Sir Robert Watson – chair of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). This is but one somber, yet realistic conclusion drawn from the most recent reports on biodiversity and ecosystem services.
By the end of March, IPBES approved four landmark science reports on biodiversity and ecosystem services for different regions of the world and published a report on land degradation and restoration worldwide. These reports, comparable to the IPCC reports on climate change, result from three years of work, involving more than 550 leading scientists from over 100 countries to assess the state of worldwide biodiversity and ecosystem services. The main findings draw a gloomy future, however not without mentioning the one or the other ray of hope.
