Targeted or tactical grazing for fire prevention is nothing new, but worthwhile to be highlighted again under the current wildfire situations across Europe.
Personally, I am a believer in large scale prescribed burning as an effective and nature friendly prevention tool. But I have to admit that the idea of producing steaks, chops and sausages through fuel load reduction grazing is also very appealing to me indeed! And it can be applied all year round! And as always, to manage fire we need a toolbox with many different tools! Prescribed burning is one, grazing another. The recent BBC report on “prescribed grazing” says it all.
Recently, the idea of resilience has started to dominate thinking about all sorts of biological and social systems. It is, in fact, quite an old idea, first introduced in 1973 by C.S. Holling, an ecologist himself. Based on his first seminal paper, Holling and others later extended the concept of resilience to a wide range of systems that include aspects of social and ecological sciences. But what is resilience? And how does it differ from stability?
Holling distinguishes resilience and stability as two opposite characteristics of ecological systems. Stability is the ability of a system to return to the same equilibrium state after a temporary disturbance. “Resilience, on the other hand, is the ability of systems to absorb change and disturbance and still maintain the same relationships between populations or state variables.”
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:
“Wildfires rage in Arctic Circle as Sweden calls for help. Sweden worst hit as hot, dry summer sparks unusual number of fires, with at least 11 in the far north” (source: The Guardian) or
“Swedish firefighters were still battling 49 different wildfires across the country on Thursday afternoon, and in some areas residents have been asked to leave for their own safety. Here’s where evacuations take place.” (source: The Local)
As we can see from this and most other media articles, reports focus on the weather, the heat and fires and smoke and on helicopters as well as water-bombing aircraft. And that is what you need in a out-of-control fire situation: Hit the fire fast and hard. And for that you need resources like planes, absolutely. However, what I do miss in most news articles is that the crisis management cycle has more phases than just the response. Is that single-focused reporting maybe a reason for 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 planned and prepared by ANW Deutschland and Pro Silva Europa. It was operationally 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.
Nature is the diversity of living organisms on Earth. It constitutes an essential element for human well-being and for ecosystems services (such as food production, water cycles, soil fertility).
In Europe several studies have demonstrated a steady loss of animal and plant species related to forest, caused for example by intensive land use, invasive alien species introduction, pollution and global warming (EEA short report on Biodiversity, 2008). Maintenance of biodiversity in forests will support its resilience to natural and human pressures. It contributes for example to the mitigation of raising temperatures and to food security.
I have recently been working on several mandatory and voluntary tools supporting nature conservation in forests, and I would like to introduce some of the most important here.
Hier ein Update zu einem erneuten Brand auf einem 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.
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?
Since 1995, the Bonn-based German expert for green impact investing ForestFinance has been planting forests in the project countries Panama, Peru, Colombia and Vietnam. Now, the reforestation company has just planted its ten millionth tree.
“In 2009, we planted and celebrated our millionth tree in Panama City in the presence of the Panamanian Minister of Environmental Affairs. Today – nine years later – we have increased this number tenfold. We have achieved this together with over 19,000 customers and environmentally conscious investors,” explains Harry Assenmacher, founder of the ForestFinance Group.
Programms of afforestation to create forests increase carbon capture and carbon sequestration, and help to anthropogenically improve biodiversity.
