Cities need to learn from nature in order to organise themselves. (Vicente Guallart, IAAC) The first day of the Urban Forestry Days 2021 kicked-off on…
Stürme, Trockenheit, Borkenkäfer – unsere deutschen Wälder standen in den vergangenen Jahren vor großen Herausforderungen.
Wussten Sie, dass viele Förster*innen in den letzten Jahren nicht nur mit großen Waldschäden zu kämpfen hatten, sondern auch unter Druck geraten sind, wenn sie wieder aufforsten müssen? Können Sie sich vorstellen, wie unser Wald in 100 Jahren aussehen wird? Was genau muss getan werden, um die Resilienz der Wälder zu erhöhen?
Cannot wait for the Urban Forestry Days (March 23-24, 2021) to be out in the forest? Our 1-minute conference trailer invites you on a journey through urban forests and green spaces from Beijing to Bonn.
The two-day collaborative event of integrated activities on Urban Forestry, hosted by the European Forest Institute (EFI), the European Forum on Urban Forestry (EFUF) and the Horizon 2020 CLEARING HOUSE project, brings together advanced practitioners, researchers, sector-leading policymakers, and everyone eager to learn about urban forestry’s latest developments in and beyond Europe. The online conference will be split into two main themes. While Day 1 addresses integrated forest management, Day 2 is themed on urban forests and health infrastructure. Further, there will be a specific focus on Sino-European collaboration. The conference will thus be run in English with Mandarin translations. Join us for lively and interactive talks and register here to secure a virtual seat.
From storm events to megafires, from drought to bark beetle damage – with intensified forest disturbance regimes during the last decades we have learned that if we want to mitigate forest risks and prevent negative impacts, we cannot only focus on emergency response and recovery. Thus, preventing disturbances and making forests more resilient has significantly gained in importance along with the insight that we need to learn how to live with intensified disturbances. In the past three years, several networking activities and events as well as fast track sharing of experiences and knowledge during forest related risks crisis have been organized in the framework of the project SUstaining and Enhancing REsilience of European Forests (SURE). These activities were aiming at promoting and further developing a European Forest Risk Facility, an evolving knowledge hub consisting of several organisations and experts from all over Europe, coming from the fields of academia, forest practice and risk management, policy and society. After three years (2017-2020) of fruitful activities within SURE, the project reached an end, and we use this opportunity to look back, reflect upon and summarize our work.
Did you know that researchers have linked extreme drought events to losses in forest productivity and widespread tree mortality on every forested continent on earth? As a result of climate change, in the coming decades we expect these drought events to increase in frequency, duration and intensity in many parts of the world, posing an emerging set of challenges at a scale that many contemporary forests have so far not had to deal with. This in turn means that we need to understand how forests respond to, and recover from, such events across a range of both temporal and spatial scales to ensure our forests are resilient to the challenges of a future climate. This understanding must cover everything from how between-tree variability buffers against stand-level change, which tree and stand attributes and management practices confer resilience, how different species growing in different locations respond to similar types of drought and what the long-term implications of these events mean for biodiversity, forest carbon, stand structure and forest growth, amongst many others. In our recent paper “Life after recovery: Increased resolution of forest resilience assessment sheds new light on post‐drought compensatory growth and recovery dynamics” published in the Journal of Ecology (Ovenden et al. 2021), we look at the recovery of trees after drought from a new perspective.

Some time ago we discussed how viewing and analyzing forest landscapes as functional complex networks could be a promising approach to increase ecological resilience to global uncertainty. Now, two new studies show how this could be applied in differently structured landscapes.
Our blue marble planet is one single interconnected organism. From plants to pollinators, preys to predators, climate to primary production, Earth’s natural ecosystems have evolved for million years to build complex and balanced interactions. Forest landscapes are also complex ecological networks, which can be depicted in many ways depending on the scale of observation. For example, if we take a look at a satellite image of a rural area (e.g., an administrative region in Germany or in southern Canada), we will immediately recognize patches of forests fragmented by agricultural crops, roads, powerlines or human settlements. In other areas, forest might cover a larger proportion of the land, resulting in a more continuous matrix. In both cases, a series of interconnected relation exists among tree species, stands, and forest patches allowing the maintenance of vital functions of such ecological system.

Um die Ziele des Projekts „Waldbrand Klima Resilienz“ in einem Video wiederzugeben, war es wichtig für mich die WKR Projektaktivitäten hautnah zu erleben. Darum nahm ich an der Pressekonferenz in Bruchsal und an einem Feuerwehrtraining in Munster teil und habe mir das Ziel gesetzt, das Thema „Waldbrand“, das eine große Medienpräsenz hat, mit einer anderen Perspektive zu behandeln. Ein umfassendes Waldbrandmanagement bedeutet eben nicht nur Brände zu bekämpfen, sondern auch Prävention und Waldumbau als wichtige Elemente miteinzubeziehen.
Das Video bringt den Zuschauern das Projekt „Waldbrand Klima Resilienz“ nahe. Es zeigt das WKR-Team und die im Projekt beteiligten vielfältigen Akteure, wie Forst, Feuerwehr, Politik und Waldeigentümer, die ihre Erfahrungen miteinander teilen und für ein ganzheitliches Waldbrandmanagement zusammenarbeiten.
Faced with biodiversity loss, climate impacts, and changes in societal demands, forest owners and managers across Europe have started to use integrated forest management to address the trade-offs between multiple uses of forest ecosystems. Integrated forest management is a highly dynamic, multi-functional management approach with as many different strategies for implementation as there are different forest ecosystems in Europe. This flexibility was showcased in the final conference of the oForest project: “How to balance forestry and biodiversity conservation – a view across Europe” organized by the Swiss Federal Institute for Forest, Snow, and Landscape Research (WSL) as well as European Forest Institute (EFI) and supported by the Swiss Federal Institute for the Environment (BAFU), the German Federal Ministry of Food and Agriculture, and the Canton of Basel. The conference, held on November 9th-11th, 2020 as an online webinar, was named after the title of the upcoming oForest book publication, which compiles expertise of integrated forest management from over 150 authors.
How can we increase the resilience of our forest to be better prepared for future natural disturbances and climate change, while maintaining a high level of wood production, carbon storage, and habitat quality for biodiversity? The project Innovative forest management strategies for a resilient bioeconomy under climate change and disturbances (I-MAESTRO) aims at improving the scientific basis for developing adequate forest management strategies. In an interview series, we are introducing the different I-MAESTRO partners and their roles in the project – and we are sharing very personal perspectives from different researchers involved. We are now introducing Mats Mahnken, PhD researcher at the Potsdam Institute for Climate Impact Research (PIK).
What is PIK contributing to I-Maestro?
PIK is involved in I-Maestro with tasks regarding forest modelling and simulation of forest dynamics taking into account environmental change effects and forest management. It is using the forest model 4C (‘FORESEE’ – Forest Ecosystems in a Changing Environment) at different spatial scales and will also be involved in work dealing with data for model comparisons and data for calibration. Thus, we are applying the expertise of the working group on Forest and Ecosystem Resilience at PIK from prior projects that focused on modelling shifts in temperature and precipitation and possible adaptive forest management on European forests as well as projects on model comparison and data harmonization.
