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.

Forest fires, field recorders, and four females 

Forest fires, field recorders, and four females 

Published March 8, 2023 by Sara Uzquiano

It is Monday, 6 am. My Colleague Patricia and I (working for Land Life Company) are leaving our office in Burgos heading to Ribera de Folgoso (León), where our SUPERB colleagues from CESEFOR Judit and Rocio are waiting for us. Today we will accompany them to collect and place again field recorders in the plots of our Spanish SUPERB demo in Castilla/León. 

Within the SUPERB project, we have 12 Demo-areas across Europe. In our Spanish demo we amongst other activities investigate degraded areas after a recent wildfire, and look at different states of forest recovery. In this regard, the aim of the field recorders is to identify different bird and bat species present across all these different recovery levels. Birds and bats play a very important role in many habitats as pollinators, insect controllers, dispersers, “reforesters” by regurgitating, defecating, or burying seeds, and they help the tree to “awake” the seed as it passes through their digestive system. Finally, they are of course indicators of biodiversity. Thus, their presence, or absence, can tell us a lot about the state of our forest.

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”.

Talking through research landscapes

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.

Let’s talk fire: How to move Integrated Fire Management forward?

Let’s talk fire: How to move Integrated Fire Management forward?

Published October 26, 2022 by Carmen Rodríguez

The last training of the Pyrolife project for its 15 Early-Stage Researchers (ESRs) took place on the 19th-30th of September in the Netherlands. Pyrolife is an Innovative Training Network funded under the Marie Curie Programme (MSCA-ITN) which supports the PhD training and research of 15 candidates working on wildfire-related issues across different European countries, covering a wide array of disciplines from engineering to human geography and sociology.

The whole Pyrolife training program is designed and anchored upon the recognition of the urgent need for change in the way our (highly heterogeneous) societies manage, govern and relate to wildfires across the globe. The project takes up the imperative of building landscape resilience through a better understanding of fire drivers, risk, and impacts, as well as creative approaches to risk reduction that are sustainable in the long term.
