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.
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?

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.

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.

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.
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.

Die Einführung von Baumarten ist ein bedeutendes und zugleich kontroverses Thema. In allen Ländern Europas sind eingeführte Arten einerseits als Chance für die Steigerung der Holzproduktion gesehen und können Alternativen für eine sich unter dem Einfluss des Klimawandels verändernde Artenzusammensetzung in Wäldern darstellen. Andererseits können eingeführte Arten auch die Ursache für den Verlust an Artenvielfalt sein, natürliche Ökosysteme stören und bei ungewünschter Verbreitung hohe Kosten verursachen.
The North is getting hot! Last year with its uncommonly warm and dry spring and summer caused lot of problems to the forest and agricultural sector in the Nordic countries. In addition, Sweden suffered from extensive wildfires. Due to climate change, summers like 2018 might become the new normal. To address this, the Nordic Council of Ministers launched a project group that is a collaboration between Nordic Agri Research (NKJ) and Nordic Forest Research (SNS). SNS held a workshop “Nordic forestry in times of extreme weather” in Copenhagen, Denmark, on the 1st of March to discuss amongst the participants from the ministries and fire service, how Nordic collaboration could be strengthened to face the new challenges. Laura Nikinmaa from the European Forest Institute’s Resilience Programme was invited to be a guest speaker together with Marc Castellnou from the Pau Costa Foundation and Martin Vendelbo from the Danish Emergency Management Agency.
The European Commission recently published a report entitled: Forest Fires, Sparking firesmart policies in the EU.
Forest fires constitute a serious and increasing threat throughout Europe, particularly in Greece, Spain, France, Italy and Portugal. Currently we are also observing more and more fires in the temperate zone of Central Europe. Despite a decreasing trend in the number of fires and areas burned, observed in some countries since the 1980s, larger and more damaging fires (i.e. ‘megafires’) are challenging the suppression capacities of many wildfire protection programmes across Europe.

Um über die Waldarbeiten im Bonner Stadtwald aufzuklären, die vielerorts erst einmal auf Unverständnis stoßen, lud das Amt für Stadtgrün der Stadt Bonn für den Nachmittag des 19. Februar 2019 zu einem Waldspaziergang ein. Stadtförster Sebastian Korintenberg gab den interessierten Bonner BürgerInnen Einblicke in die derzeit durchgeführten Holzerntearbeiten und sprach über die Folgen des Borkenkäferbefalls.
