You thought that humans were the only species that can affect areas far away from where they live? Think again. The forests in India might be the culprits of the rainy days you are having in Germany now.
Recent research has shown that forests and vegetation in general can control the weather across great distances, making the forests and climate even more interconnected than previously thought according to an article published in Quantamagazine. Plants, especially trees, are fascinating organisms: they pump up water from the soil to the atmosphere and simultaneously grab carbon dioxide from the atmosphere into themselves and soils. The features that make this transportation possible are tiny pores on the leaves’ surface, called the stomata. One leaf can have more than one million stomata. So in a large forest the number of stomata is stratospheric and the amount of water they pump can be trillions of liters!
The growing group of researchers studying the interactions between vegetation and climate can now estimate how a forest loss or gain in a certain area can sway the weather patterns in others. One of these scientists is Professor Abigail Swann, the head of the Ecoclimate Lab in the University of Washington. In her recent studies, she has found the teleconnection: the plant communities around the globe are connected by the atmospheric mechanics. Essentially, the effect is similar to that of El Niño, where the warm surface water in the East Pacific Ocean causes heavy rains in South America and Africa as well as drought in Southeast Asia and Australia.

When storms are expected to become more frequent and violent, how can we ensure a flourishing future for our forests and the people who depend on them? This was one of the main questions that the SURE project workshop “Res2Storm – pan-European Workshop on Wind, Storms, and Forests” aimed at answering. The objective was to map operational tools and processes for coping with storm events along the crisis management cycle. Emphasis was given to the phases ‘recovery’, ‘prevention/mitigation’ and ‘preparedness’, not neglecting adequate ‘response’. The workshop was hosted by Christoph Hartebrodt and his team from the Forest Research Institute of Baden-Württemberg (FVA) in Freiburg, Germany, on the 11-12th of October 2018. It was the first in a series of thematic workshops within the SURE project dealing with forest risks. It brought together 35 participants from 13 European countries with backgrounds in science, policy and practice.
What does resilience mean to you? Is it the ability to endure stress and still be able to perform? Or the capacity to recover after a catastrophe? Either answer could be right, as the definition of resilience is under a continuous debate. However, as current forest policies advocate building resilience with forest management, they create a point of frustration for forest managers: how do you implement something that you are not exactly sure of what it means in the first place? We tackled this problem with a workshop “Operationalizing Forest Resilience”, that was organised on the 6th and 7th of September 2018 in Bonn. We invited scientists from Europe and the USA to discuss how we can help forest managers to implement resilience in practice. And it is not as easy as you would think.
How does the German forest look like for visitors from the north? There are taller trees and the exotic European beech, but the Norway spruce reminds us of home. We exchanged that and some other thoughts with a delegation from the Finnish Ministry of Agriculture and Forestry who visited the Bonn Office on the 29th of August. They were hosted by colleagues from the German Federal Ministry of Food and Agriculture (BMEL) who also participated in a field visit to an urban forest in Bonn.
After a brief introduction about the EFI Resilience Programme, we had the opportunity to visit the Jägerhäuschen Marteloscope site, where Uwe Schölmerich, the head of the Regional Forest Enterprise Rhein-Sieg-Erft, kindly guided us.
Despite the obvious differences between German and Finnish forest ecology and management, many of the challenges we face are similar. Bark beetles have been causing damages in both countries for a long time, and the exceptionally hot and dry summer brought forest fires to the agenda in an entirely new way. Halting the loss of biodiversity is also an important part of current forest management and planning even if the systems are different.
Forest managers and other interested groups learn about integrated forest management in both countries. The use of demonstration sites such as e.g. Marteloscopes has proven a valuable tool for educating and creating a dialogue among various interest groups relating to different aspects of forest management. The Finnish delegation at the Jägerhäuschen Marteloscope clearly recognized it. They suggested adding a carbon sequestration component to the I+ software training tool which allows to visualize, how forest management decisions affect the carbon balance of the site and how wood products from harvested wood contribute to store carbon over many years. We thanked the Finnish delegation for this valuable input and expressed our hope that Marteloscopes may also find application in training and education in Finland in the near future.

On 6th of June 2018, EFI Bonn’s principal scientist Marcus Lindner and I, Junior researcher Laura Nikinmaa escaped tropical Germany to cool down in the Mediterranean Solsona, Spain, and to participate in the conference “COMMUNICATING RISKS IN Decision Support Systems: from basic research to advanced decision support tools” with 30 other researchers. Hosted by the Forest Science Centre of Catalonia (CTFC), the conference was organized by the SuFoRun project and IUFRO’s Risk Analysis working group 4.04.07. The program provided plenty diverse presentations ranging from using real option analysis to deal with uncertainties to effects of bark stripping on wind resistance of Norway spruce.
Strengthening weaknesses is one of the starting points in any management or developing plan, but what to do when even identifying them is tricky? Such is the problem forest managers often face while trying to predict and prevent storm damages to forests. The current models to predict storm damages suffer from lack of data, and the expected increase of severe storms caused by climate change adds its own spice to the mix.
Do you think that the weather during the last ten years or so has been wilder than during the good old days? Well, it is not just you! A study from European Academies’ Science Advisory Council (EASAC) shows that extreme weather events have become more frequent over the last 36 years. The increase in frequency can especially be seen in floods and other hydrological events, but also in storms and extreme temperatures, drought and forest fires. It is likely that we are just getting the appetizers and the main course of the more turbulent weather is yet to be served.
The increase in the frequency of the extreme weather events causes more threats to forests. Events that used to occur once in a hundred years might now happen once in a quarter century. Disturbances are also moving to new areas, as seen in the winter fires in Norway in 2014 or wind damages in Catalonian forests the same year. Local knowledge on how to deal with these events might be lacking, which can lead to high economic and sometimes even human losses.
What can be done then to mitigate these changes? In the European Forest Institute, we believe that exchanging the best available information and mutual learning between practice and science across borders is the most efficient way to adapt and deal with the extreme weather. Connecting expert knowledge and the ones in need of it is important in all the faces of crisis management: prevention, preparation, response and recovery. The European Forest Risk Facility offers exactly that: bringing together experts from science and practice, exchanging knowledge and inspiring to learn new ways to manage forests in the face of more extreme weather. This also involves discussing and thus avoiding to repeat the failures that other have made before. If that happens, a failure can still become a “fantastic failure” to learn from – and the European Forest Risk Facility will provide a platform for that.

To round up an already eventful week at the EFI Bonn, EFI-Senior Expert Alexander Held took us (Laura Nikinmaa, Junior Researcher and Johanna Strieck, Communications Trainee) last Friday, February 24th to controlled heathland burning to the Drover Heide, nearby Bonn, to learn more on fire management and to get an idea of its practical application in the field. It was a great day for making your first experiences with controlled burning, and the compact small-scale operation on 10-15 ha allowed plenty of time for explanations. Sun exposure and wind speed was quite high and the level of humidity was moderate to high.
The website for the project “SUstaining and Enhancing REsilience of European Forests” – or briefly SURE – is launched. It provides all the important information on the project, upcoming events, as well as material on the RISKplatform, a virtual communication tool for the European Forest Risk community.
If you are interested in experiences from both practice and science on how to best cope with risk and respond to disturbances, if you want to learn about developing and improving response strategies in policymaking and practical management be sure to check out the new website!
Coordinated by European Forest Institute’s Bonn Office and funded by the German Federal Ministry for Food and Agriculture, SURE is aiming at enhancing forest resilience and addressing disturbance related risks as an integral part of sustainable forest management through facilitating networking, learning and capacity building.
Fire is not only a threat to forests and livelihoods in the rural areas. As the forest fire season takes on entirely new dimensions by getting longer and more intense, fire – and smoke related health hazards increase, warned an international study published in Atmospheric Chemistry and Physics and reported by PhysOrg.
Burning vegetation releases small particulates, that are dangerous even in small quantities. According to the study, in countries with effective measures to reduce air pollution, wildfire emissions are not causing the average annual levels of small particles to surpass the World Health Organization’s (WHO) recommended thresholds. However, emissions from fires do increase air pollution severely, which in turn can have grave consequences for human health. According to WHO, the range of health effects of the small particulates is broad, but are predominantly to the respiratory and cardiovascular systems. In principle, the longer the exposure to small particulates is, the more severe the impact on health is.
Tragically, it is estimated that more than 700 000 hectares of land have burned in 2017 alone. The data from European Forest Fire Information System (EFFIS) points out that the majority of fires were caused by human activities. Additionally dry conditions paved the way for small fires to turn into uncontrollable wildfires. Both conditions, on the bright side, indicate that there is potential for fire prevention.
Currently, air quality policies do not include wildfires and the emissions they cause. Additionally, up until this point there is no widely approved way to manage wildfires. In the light of the late megafires, there is an urgent need to collaborate on the international level to find the best approach to manage and prevent wildfires. For the sake of our forests and our health.
