Können wir durch großflächige Wiederbewaldung den Klimawandel stoppen?

This blog post was translated and is now available in English here

Letzte Woche hat das Magazin Science eine viel beachtete Studie der Arbeitsgruppe von Prof. Crowther vom Institut für Integrative Biologie der ETH Zürich publiziert, in der mithilfe von Satellitenaufnahmen, Felddaten und Computermodellen das enorme Potential von großflächiger Waldvermehrung für den globalen Klimaschutz herausgestellt wurde.

Das Besondere an dieser Studie ist der Fokus auf „Restoration“, also Wiederbewaldung. Es gibt viele Abschätzungen zu CO2 Minderungspotenzialen durch Aufforstungen, und es ist wichtig, bei solchen Abschätzungen den Landbedarf einer wachsenden Weltbevölkerung sowie aus anderen Sektoren realistisch abzuschätzen (Canadell and Schulze 2014). Die Autoren der Studie haben daher von der global theoretisch möglichen Waldfläche den Flächenbedarf für Landwirtschaft und Siedlungen abgezogen. Als Resultat ergab sich eine riesige Fläche von fast 1 Mrd ha für potenzielle Wiederbewaldung.

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.”

Deadwood management in production forests

Written by Lucie Vítková

“Deadwood has a major role for the conservation of saproxylic species and contributes to carbon sequestration, nutrient supply, natural regeneration and protection against falling rocks.” (Lachat et al., 2013:92)*

A substantial amount of literature on the importance of deadwood in Central European forests has been available providing partial recommendations to enhance deadwood-dependent biodiversity. However, a comprehensive review of science- and forestry experts-based recommendations effectively enhancing deadwood bearing in mind operational implications has not been presented in international literature.

Wald-Wild-Klima! In Brandenburg haben sich die Wildbestände seit 1957 mehr als verzehnfacht

Anlässlich des 10-jährigen Bestehens des Landesbetriebs Forst Brandenburg gratulierte Forststaatssekretärin Carolin Schilde in Ihrem Grußwort allen Verantwortlichen und betonte dabei die Bedeutung des Waldumbaus in Zeiten des Klimawandels.

Noch sind 500.000 ha des Brandenburger Waldes reine Kiefernbestände. Die Folgen der Kiefernreinwirtschaft seit ihrem Beginn vor über 200 Jahren werden auch erst in Generationen zu bewältigen sein. „Forstleute wissen, dass eine Beimischung von zirka zehn (Prozent) Laubholz bereits wesentlich dazu beiträgt, dass Massenvermehrungen von Kiefernschadinsekten einzudämmen. Uns allen muss klar sein, dass der aktive Waldumbau mit Fördermitteln keine flächendeckende Lösung sein kann“, fasste die Staatssekretärin zusammen.

The Forest Biodiversity Programme METSO – voluntary forest conservation and management in private forests

During the meeting of the European Network Integrate in Toruń, Poland, Sanna Kasurinen, from the Finnish Forest Centre, presented the METSO-programme, an initiative aiming to halt the ongoing decrease of biodiversity of forest habitats and species in Finnish forests. The Forest Biodiversity Programme in particular addresses private forest owners. The overall objective is that based on a voluntary agreement, nature conservation is enhanced and communication improved on biodiversity of forest habitats and ecosystem services amongst stakeholders.

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.

Managing forests as functional complex networks

Although a variety of forest management approaches to cope with climate change have been proposed worldwide, what has been missing so far is a way to integrate them at appropriate scales, particularly at landscape level, and to put a primary focus on enhancing forest resilience in the Anthropocene.

I suppose that readers of the Resilience blog do not need a long introduction on the myriad of threats that the climatic and global changes pose to forest ecosystems. Mutating climate, drought, unexpected extreme disturbances, sudden shifts in socio-economic conditions but also forest fragmentation, pollution and new pest and diseases are making long-term forest planning more and more difficult. Scientists are still debating on the topic, but many are convinced that we entered in a new geological era: the Anthropocene. How can we therefore manage our forests so that they are more resilient to the high level of uncertainties that characterize this new era?

Beech leaf disease affects American trees and raises concerns for European forests

By: Carrie Ewing, PhD Student at The Ohio State University

We are always happy to have “guest-authors” who give us an insight into their work. Carrie Ewing, PhD Student at The Ohio State University, is currently researching tree genetics to determine the plant pathogen(s) that are causing beech leaf disease (BLD), a new and seemingly lethal disease affecting American beech trees (Fagus grandifolia).  

The disease was first discovered in forests in the northeastern United States and parts of Canada. John Pogacnik, a biologist at Lake Metroparks in Ohio, first observed BLD in 2012 in northeast Ohio, U.S.A.  The disease has been spreading rapidly and has now affected forests in Ohio, Pennsylvania, New York State, and Ontario, Canada.

Happy International Day of Forests!

Written by José Bolaños and Maria Schlossmacher

This year the International Day of Forests (IDF) will address the exciting theme “Forests and Education”. It is an occasion to raise awareness, to inform and to educate a broad public, different stakeholders and forest-managers about forest-related topics.

Forests cover one third of land on Earth, and they perform crucial and vital functions around the world. Trees improve our lives both at a grand scale and at the local level. Despite those benefits, deforestation and consequences of climate change are among other great challenges for forests.
