ForestMoocForChange: join the first free online course on Continuous Cover Forestry

Published September 27, 2023 by Jonathan Spazzi

Today forests are under increasing pressure: on one side society demands productivity and multipurpose use, while on the other side there’s increasing pressure from climatic extremes and intensification of forest disturbances.

We need constructive responses to these pressures like integrative forest management approaches and close-to-nature solutions to both enable the multipurpose value of our forest as well as to enhance their biodiversity and resilience in the face of climatic disruption. However, one of the main hurdles to enable new management systems is the general lack of knowledge and expertise on alternative management options available, and we have a solution for that!

ForestMoocForChange is a new and free online course providing an introduction to continues cover forestry, covering the various aspects of this innovative forestry approach over an 8-week period. The course includes numerous videos produced in the field by experts, managers and owners. Each week, a live meeting will be organised with the speakers enabling you to ask your questions and discuss the subject covered. From discovering how continuous cover works and its dynamics, to questions of an economic, ecological or social nature, the MOOC is designed to be comprehensive and aimed at everyone.

Interview mit Axel Schopf zur Erforschung natürlicher Gegenspieler von Forstschädlingen

 Darüber habe ich mit Axel Schopf, Professor i.R. an der Universität für Bodenkultur in Wien und Berater  in dem Team des Eichenresilienz-Projekt gesprochen, in dem European Forest Institute mit dem Landesbetrieb Wald und Holz im Wissenstransfer zusammenarbeitet.

Die Durchführung des Projektes „Erhebung der Parasitoiden der Frostspanner-Arten Operophtera brumata und Erannis defoliaria sowie des Eichenwicklers Tortrix viridana“ erfolgt am Institut für Forstentomologie, Forstpathologie und Forstschutz (IFFF) an der BOKU Wien unter der Leitung von Frau Doz. Dr. Christa Schafellner. Ihre Aufgabe war, den Parasitoidenkomplex (Parasitoide = Raubparasiten, die als natürliche Gegenspieler von Schädlingen diese letztlich abtöten) der dominierenden Eichenschädlinge Kleiner und Großer Frostspanner (Operophtera brumata, Erannis defoliaria) und Grüner Eichenwickler (Tortrix viridana) in ausgewählten Eichenbeständen im Münsterland zu untersuchen. Ziel der Untersuchung war es, in Folge die Möglichkeit einer Steigerung der Widerstandsfähigkeit von Eichenwäldern durch bestimmte Förderung und Ausbringung von natürlichen Gegenspielern der Eichenschädlinge zu bewirken.

New FORWARDS project will provide crucial information on European forests’ vulnerability to climate change

Climate change has already had a deleterious impact on forests ecosystems and silviculture in various parts of the world. But healthy trees translate to healthy citizens: everyone benefits from forests’ clean air, safe food and water, and recreational space.

With a total budget of €14m funded by the European Commission’s HorizonEurope (plus additional funding by Switzerland and the UK) and more than 19 partners (incl. European Forest Institute) involved, the FORWARDS project (ForestWard Observatory to Secure Resilience of European Forests) will provide timely and detailed information on European forests’ vulnerability to climate change. The project will also deliver science-based knowledge to guide management using the principles of climate-smart forestry, ecosystem restoration, and biodiversity conservation. With its activities, FORWARDS aims at supporting European forests and society to transform, adapt, and mitigate climate-induced changes.

<strong>Experiencing an excursion through the eyes of a forest modeler</strong> 

Experiencing an excursion through the eyes of a forest modeler 

Published February 7, 2023 by Marc Grünig

For the RESONATE project, my task aims at developing high resolution future forest trajectories and disturbance maps for the European continent. Continental scale modelling always comes along with trade-offs regarding the detailed processes. Taking this into account, we follow a bottom-up approach, where we use detailed information from local process-based forest simulations to train deep neural networks. For this, we collected forest simulations under different climate scenarios from hundreds of locations across Europe, covering large gradients of environmental and climatic conditions. By combining simulations from different regions, we can explore the relationship between forest dynamics and climate signals using deep neural networks. These neural networks learn to represent forest dynamics depending on environmental and climate conditions, allowing us to upscale the forest dynamics to continental scale. We believe that with this approach we will make a step towards better capturing local scale dynamics at the macroscale.  

But guess what, forest modeling means we spend most of the time in front of our screen, working on code and data that eventually allow a glimpse into the future of forest ecosystems. Although I spend a lot of my leisure time hiking, cycling and sometimes ski touring in the mountains, professionally I spend very little time in the field. Therefore, I was really happy to join the excursion as part of a conference we organized in Berchtesgaden some months ago. The occasion to go to the field with colleagues who spend a lot of time there and visit the system that I am currently modelling is very special and of course informative. And for me, coming from a macroecology background, it is also particularly important to see gradients in the mountain landscape and discuss their impact on vegetation processes as well as disturbances.

‘Europe’s forests increasingly under pressure from climate-driven disturbances 

‘Europe’s forests increasingly under pressure from climate-driven disturbances 

Published December 12, 2022 by Marco Patacca

Every summer we see in the news flames burning down trees and houses, firefighters pouring water on mountain sides. In the winter we see massive windstorms blowing off entire forest landscapes. We read about very small insects that kill millions and millions of trees in few years. 

In parallel, we are also observing trees becoming political in Europe. Placed at the core of many policy documents and climatic pledges, forests and their climate mitigation potential are being increasingly recognised as key in the critical achievement of European climate and biodiversity targets, as well as for the many other services they provide to society.  

Media and policy attention underline that we urgently need more knowledge and sound research results on how disturbances develop, how they impact European forests and the so-called “ecosystem services” they provide, and how to respond to the seemingly increasing forest disturbance risks. A team of forest researchers from Wageningen University, the European Forest Institute and numerous research institutes across Europe investigated forest disturbances over the past 70 years and can now provide ground-breaking results in the paper “Significant increase in natural disturbance impacts on European forests since 1950” published in the journal “Global Change Biology”.

Reflections on inter-generational interactions in science and the potential of young scientists 

Imagine you are sitting in a room full of people for three days. Listening to a lot of presentations which do not necessarily light up your interests. You make the effort to resist the temptation of checking your mailbox. Feeling guilty for seeing work accumulating, knowing you will have to address part of it at night, alone in your hotel room. Eventually, you will be presenting your work and – if you are lucky – have an awesome 20 minutes of lit discussion and feedback. But after that, you will rely on coffee again to fight back the gravity attacking your eyelids, especially in the post-lunch sessions. You will be looking forward for the drinks at the end of the day to socialize a bit and get to know people. 

In my short, young scientist’s experience, that’s how I’ve portraited – and experienced – scientific conferences. 

A (much needed) alternative 

Well, the latest conference I attended was absolutely nothing of the above.

Wrangling resilience from concept to forest management application

Wrangling resilience from concept to forest management application

Published August 31, 2022 by Laura Nikinmaa

Record breaking temperatures, minimal rainfall, drying rivers and burning forests. The news from this summer show how acutely the warming climate is affecting our environment and lives. To me, the damages to forests due to fires, drought and insect outbreaks are particularly worrisome as we as a society are counting on forests to sequester our carbon emissions, to replace the fossil fuel products and to foster biodiversity that is rapidly declining. This concern on the capacity of forests to cope with increased disturbances started years ago and led me to pursue a PhD on forest resilience and how it could be improved with forest management. Now it is time to summarise my work from the last four years.

How we can better understand our forest ecosystems with laser scanning

How we can better understand our forest ecosystems with laser scanning

If you want to investigate the influence of management on forest resilience after disturbances, you can of course put your walking shoes on and do field measurements. However, how can you evaluate forest areas of several hundreds of square kilometers? In forest science, we consider Airborne Laser Scanning (ALS) a strong solution for mapping forest characteristics – including forests’ internal structure – at high resolution over wide areas. ALS is a remote sensing technology based on the emission of laser pulses. The laser light can penetrate the tree canopy and reflect on objects located inside the forest, or even by the ground. The Earth’s surface is then modelled as point clouds in three dimensions with geometric information on the height of the vegetation, but also on its internal structure. In the project Innovative forest management strategies for a resilient bioeconomy under climate change and disturbances (I-MAESTRO), we used ALS for two purposes: describing the forests to get an initial state for simulations, and analysing forest dynamics with repeated measurements.
