Der tote Taucher im Wald – Gedanken zur Feuerbekämpfung aus der Luft

Vielleicht erinnert sich noch der ein oder andere an den Tatort „Der tote Taucher im Wald“. Ein Löschflugzeug schöpft Wasser, ein Taucher landet in einem Waldbrand…Die gegenwärtige Diskussion über Löschflugzeuge in Deutschland erinnerte mich jedenfalls daran.

Während wir schon jetzt bis August 2019 teilweise überraschende Ausmaße der Waldbrände feststellen müssen, wird kontrovers über den Umgang mit Feuer und den möglichen Löschmöglichkeiten diskutiert. Auch wir haben uns zum Thema integriertes Feuermanagement hier auf diesem Blog hinreichend geäußert und wollen nun auch zur Diskussion über Löschflugzeuge beitragen, im Folgenden ein paar Gedanken.

EFI as chartered member of PyroLife

Deadly wildfires in the past two years and the heatwave we are facing throughout in Europe this year are a glimpse of what to expect in the future. Therefore, the European Union has granted 4 million Euro for PyroLife, a project in which framework a new generation of experts will be trained in integrated fire management. We are happy to announce that we will take part in the newly established project.

PyroLife is the first integrated doctoral training programme on wildfires globally and will train 15 PhD candidates across Europe, coordinated by Wageningen University & Research.

Within this project, the European Forest Institute will supervise one PhD student and further offers various fire related trainings through the SURE project.

Polish-German exchange on wildfire prevention

Written by Michael Herrmann, ForestFireWatch and Alexander Held

„One firefighter within the first 15 minutes is worth more in the forest than 100 firefighters after an hour” – motto of Polish forest fire protection services, emphasizing the importance of initial attack

From 6-7 June 2019, Polish forest officers from the State Forests organization, firefighter and representatives of the Forest Research Institute met with members of the German volunteer organization “ForestFireWatch” for an exchange of knowledge and experience in Rzepin (Forest District), Poland. Main objective of the meeting was the exchange of experience in the field of wildfire prevention.

rescEU put into practice!…partially.

The current heat wave does not only create a feeling of summer holidays but above all, it puts fire and rescue services as well as foresters on constant alert.

At the same time, the rescEU plan is getting into its next phase, which is good news. RescEU is the common European response to disasters by strengthening the EU’s collective ability to react.

Especially in consideration of the high risks of forest fires, the Commission has launched the first fleet of firefighting aircraft under the new rescEU systems, consisting of two aircraft from Croatia, one aircraft from France, two aircraft from Italy, two aircrafts from Spain, and six helicopters from Sweden. The Commissioner for Humanitarian Aid and Crisis Management Christos Stylianides stated: “With rescEU, we have put words into action. We have delivered a practical tool for citizens that can save thousands of lives in the future. RescEU means having a much stronger, pan-European civil protection system.”

Springtime in flames

and Alexander Held

What had already been predicted in 2018, became true.

Spring is too warm and too dry, again. The year 2019 had a hot start: during the first four months, more areas have been burned than during the entire 2018 across Europe. The Joint Research Centre’s European Forest Fire Information System (EFFIS) of the EU Science Hub recorded 1233 fires corresponding to a burned area of more than 250 000 ha by the end of April. In comparison, there were 1192 fires burning 181 000 ha during the whole 2018.

New winds in dealing with forest disturbances

For a young professional in the field of forestry, reading the news nowadays is a schizophrenic experience. On one hand, I’m scared to death with the heat waves and drought occurring at odd times of the year, continuously increasing CO2 concentrations in the atmosphere, alien species invasions in new areas and massive insect outbreaks in various parts of Europe.  On the other hand, it is very exciting and hopeful: climate change awareness is increasing, and actions are being taken, wood product innovations are replacing many fossil-fuel based ones, and biodiversity conservation measures are adopted by many forest managers. Nevertheless, we are facing a serious situation that cannot be fixed with few tricks. With the disturbance frequency and intensity increasing all the time, we need to revise how we manage the risks they are causing to our forests.

Extreme Trockenheit führt zu hoher Waldbrandgefahr

Von Alexander Held & Maria Schloßmacher

Aufgrund akuter Waldbrandgefahr herrscht in vielen Regionen Deutschlands und darüber hinaus derzeit die höchste Warnstufe. Bereits vor Ostern musste die Feuerwehr zahlreiche Waldbrände löschen.

Der Waldbrandgefahren-Index des Deutschen Wetterdienstes (DWD) stuft vor allem Brandenburg, den Süden Mecklenburg-Vorpommerns, das nördliche Sachsen und den Osten Sachsen-Anhalts als stark gefährdet ein. Im nördlichen Sachsen dürfen wegen der hohen Brandgefahr einige Wälder nicht von der Öffentlichkeit betreten werden.

Gründe für den Ausbruch des Feuers sind vielfältig und doch leicht auszumachen. Die Kombination aus dem Rekordsommer 2018 und die anhaltende Trockenheit haben den Wäldern zugesetzt, sodass die letzten (Wasser)-Reserven aufgebraucht sind. Sollten sich die Prognosen über ein weiteres Dürrejahr 2019 bestätigen, werden auch die Zahlen der Waldbrände weiter drastisch steigen. Trockene Pflanzenreste und der Wind tragen zum Ausbruch des Feuers bei. Der Wind trocknet altes Gras, noch bevor das neue Grün wachsen kann und begünstigen so die schnelle Ausbreitung des Feuers. Da die Bäume erst langsam beginnen ihre Blätter zu bilden, kann die Sonne ohne Schutz bis auf den Waldboden scheinen und trockenen Pflanzenteile sind leichter entflammbar. Dadurch ist die Waldbrandgefahr im Frühling besonders hoch einzuschätzen.  Wind und Trockenheit, mehr noch als die Temperatur und die warmen Tage über dem Osterwochenende, spielen dabei eine entscheidende Rolle.

No storm clouds without silver linings

Written by Alexander Held, Andrea Ortiz, Maria Schloßmacher

Two major storms, Eberhard and Franz, hit Germany and so its most populous state, North Rhine-Westphalia, last week. Experts are still assessing the full extent of the damage, but what is clear: this huge damage will have long-term impacts on forests. It also demonstrates once again the extent of enormous damages that are caused by storms and the related secondary damages like bark beetle infestation.

Resilience: the ball-and-cup metaphor


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.
