The heatwave across central and northern Europe is preparing the ground for a severe wildfire season. Normally mostly green vegetation is turning into “fuel” in countries normally not affected by serious fire problems. Hereby I am referring to countries not prepared for a wildfire season (compared to the Mediterranean areas, who are dealing with frequent forest fires), despite the climate change scenarios and increasing risks and disturbance predictions.
We have reported here on this blog about the fire situation and early warning systems in the UK, Ireland, and Germany already. Now Scandinavia is receiving a lot of media attention. Sweden for instance is calling for international assistance:
However, what I do miss in most news articles is the fact that the crisis management cycle has more phases than just the response. Is that single focused reporting maybe a reason for the political ignorance of urgent needs for prevention and mitigation?
A short report on the annual Pro Silva Europa meeting in Weimar, Germany
Pro Silva is a European federation of professional foresters across 24 European countries (and more recently in New England, USA) who advocate and promote Pro Silva Close to Nature Forest Management Principles as an alternative to age-class forestry to create and maintain resilient forest ecosystems. Increasing forest resilience was also the motivation to create Pro Silva 29 years ago.
This year, the annual meeting was hosted by ANW Thuringia and the state forest administration of Thuringia in and around the city of Weimar on 20-23 June 2018. The Pro Silva Program addressed topics such as forest conversion from age-class to continuous-cover forestry, re-introduction of silver fir (and other climate-change-relevant tree species) and the ungulate-silviculture challenge of converting European forests to more biodiverse, stable and resilient forests.
Here we would like to provide you with recent updates:
After responding to 50 wildfires over the past two weeks, Collite urged the public not to engage in “fire tourism” as forest and gorse fires continue to rage across the country amid hot, dry conditions. https://www.irishtimes.com/news/environment/coillte-warns-public-against-fire-tourism-1.3556266
The president of a protection association overseeing a natural area near Villers-lès-Nancy lamented the destruction done to birds’ nesting grounds by an 8-hectare wildfire which roared through the area several days ago. https://france3-regions.francetvinfo.fr/grand-est/meurthe-et-moselle/nancy/espace-naturel-sensible-incendie-villers-nancy-1507109.html
Hier ein Update zu einem erneuten Brand auf ehemaligem Militärgelände (Quelle: Spiegel online) und meine Kommentare dazu.
In Deutschland, vor allem im Osten, gibt es tausende Hektar aktive oder ehemalige Truppenübungsplätze. Naturschutzfachlich sind diese Flächen auf Grund der ehemaligen militärischen Störung äußerst wertvoll und zumeist auch NATURA 2000- Flächen. Leider sind die militärischen Hinterlassenschaften (UXO Unexploded Ordnace) nicht so wertvoll, sondern gefährden Umwelt, Boden, Grundwasser und im Falle von Wildfeuern auch die Einsatzkräfte.
Zwei Fragen stellen sich: Wie können wir den Offenland-Charackter dieser Natura 2000 Flächen erhalten und gleichzeitig die Sicherheit der Einsatzkräfte im Brandfall erhöhen?
A very sunny June 2018 was also a very dry June! And I mean dry:
The sunshine duration in June with about 215 hours of sunshine reached 108 percent of the target of 198 hours. Persistent drought in the northeast, severe thunderstorms in the southwest:
At around 50 l / m², June reached only 57 percent of its target nationwide (85 l / m²). The month was very poor in Thuringia and Saxony-Anhalt, which had already been part of the drought affected areas in May. In Wittenberg for instance, from April 27 to June 20, only 0.9 l / m² were recorded. The drought had a catastrophic effect, because in addition to numerous wildfires, agriculture and forestry is already suffering enormous drought related damage.
Discussing solutions and searching for more resilience forests
How are different European countries dealing with bark beetle outbreaks and which role do questions like sanitary cutting, monitoring systems, forest ownership, windstorms and expectations towards nature conservation play? What are the challenges regarding climate change? How do the social perception of active and inactive forest management impact forester’s activities in local forests? Which tools should be used to cope with natural disturbances and how we can educate foresters, policy makers, and other relevant stakeholders? Following the invitation of the Polish Ministry of Environment and the Polish State Forests, we discussed these and more issues in the Białowieża Forest during a working seminar of the European Network INTEGRATE from 25-27 June 2018.
The dry weather pattern over the northern parts of Europe are more stable than we like it to be… Ireland’s Forest Service, part of the European Forest Risk Facility network, has issued a RED fire danger warning, while the UK is burning already.We are observing these conditions more often now, outside the fire prone regions of the Mediterranean. Is this a sign of things to expect under climate change scenarios?
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.
Thanks to the careful observation of colleagues at Universidade de Trás-os-Montes e Alto Douro (UTAD) we are able to report an unusual “record”: As of 11 June 2018, the largest burnt forest area in this year so far in Europe can be found in the United Kingdom. We are looking at 8049 ha of burnt area – that is more than the combined burnt area of Spain, Portugal, France and Italy together.
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.
