It is Monday, 6 am. My Colleague Patricia and I (working for Land Life Company) are leaving our office in Burgos heading to Ribera de Folgoso (León), where our SUPERB colleagues from CESEFOR Judit and Rocio are waiting for us. Today we will accompany them to collect and place again field recorders in the plots of our Spanish SUPERB demo in Castilla/León.
Within the SUPERB project, we have 12 Demo-areas across Europe. In our Spanish demo we amongst other activities investigate degraded areas after a recent wildfire, and look at different states of forest recovery. In this regard, the aim of the field recorders is to identify different bird and bat species present across all these different recovery levels. Birds and bats play a very important role in many habitats as pollinators, insect controllers, dispersers, “reforesters” by regurgitating, defecating, or burying seeds, and they help the tree to “awake” the seed as it passes through their digestive system. Finally, they are of course indicators of biodiversity. Thus, their presence, or absence, can tell us a lot about the state of our forest.

The Return of the Woodpecker
It was an early arrival at the airport for departure on Saturday morning, packed with several layers of clothing and warm shoes. This time the trip was up North, with final destination Umeå to visit SUPERB’s Swedish demo area. We were first flying to Stockholm and from there taking the train onwards to Umeå. While looking out of the window from the airplane close to Stockholm, we noticed that everything was still very green, no snow in sight. Or at least not yet.
At the train station we met with Magda, deputy project coordinator of SUPERB, who was also joining us. As we didn’t see any snow yet, we made a bet after how much time on the train we would see full snow cover. Of course, a full snow cover needed to be defined; “Enough snow to not wreck your skis.” Apparently, this was still open for own interpretations. In the end we were all too optimistic. It took longer than expected to reach our expected “winter wonderland”. But we had some beautiful views during the train ride, and the sunset was spectacular.
During dinner that night in Umeå we had our second Swedish experience, eating reindeer. We would learn more about the role of reindeer for Swedish forests and forest-depending communities later. But now, after such a long travel day and a tasty dinner, it was time for a good night of sleep, so we would be well rested for the next day, exploring the demo area.

Oaks can live up to a thousand years and grow to trees of impressive magnitude. They are of great importance, economically and ecologically. Oak wood is hard and resistant and provides a valuable resource for the market. And with over a thousand species of beetles, butterflies, birds and bats, fungi and more living on oaks, these trees are a real biodiversity hotspot.
Since the mid-1980s, however, the condition of oaks in Europe has deteriorated dramatically. This is due to an interaction of climatic extremes, such as drought or late frost, herbivorous insects and mildew. Among these stress factors, insect damage by early defoliators is of particular importance. Oaks generally show a strong ability for regeneration and can regrow their foliation even after complete defoliation. However, if severe defoliation in spring occurs repeatedly or in combination with a second stressor, the oaks’ energy reserves cannot be restored and the tree is lost.
The critical question is: how can we make oaks more resilient? And are there ecological means to combat oak decline? In Germany, committed people from forestry practice and science have joined forces to find solutions. The project “Oak Resilience” investigates the resilience of the native pedunculate oak and sessile oak and looks into predatory parasites –called parasitoids– of the most important early defoliators in oaks, the winter moth Operophtera brumata, the mottled umber moth Erannis defoliaria and the oak leafroller moth Tortrix viridana. Parasitoid insects are natural antagonists of defoliating insects and are an important regulatory force in the ecosystem. The project will develop recommendations for silvicultural measures to support these natural regulating forces in order to strengthen the oak’s vitality and forest resilience in general. The project is led by Wald und Holz NRW and funded by the FNR (Agency for Renewable Resources; FKZ 22017517). Watch this video to get an introduction to the project – and check our Resilience blog for upcoming project results in 2023.

New FORWARDS project will provide crucial information on European forests’ vulnerability to climate change
Climate change has already had a deleterious impact on forests ecosystems and silviculture in various parts of the world. But healthy trees translate to healthy citizens: everyone benefits from forests’ clean air, safe food and water, and recreational space.
With a total budget of €14m funded by the European Commission’s HorizonEurope (plus additional funding by Switzerland and the UK) and more than 19 partners (incl. European Forest Institute) involved, the FORWARDS project (ForestWard Observatory to Secure Resilience of European Forests) will provide timely and detailed information on European forests’ vulnerability to climate change. The project will also deliver science-based knowledge to guide management using the principles of climate-smart forestry, ecosystem restoration, and biodiversity conservation. With its activities, FORWARDS aims at supporting European forests and society to transform, adapt, and mitigate climate-induced changes.

Developing a Local Urban Forestry Action Plan
Are you interested in gaining a quick overview of the huge potential that urban forestry offers to solve environmental, social, and economic challenges in cities? Do you want to learn how increasing the presence of trees and other vegetation in cities can contribute to urban resilience? EFI’s Urban Forestry Team members from the Resilience Programme in Bonn (Juliet Achieng Owuor, Ian Whitehead and Rik De Vreese) have recently been involved in editing and co-authoring a new publication, entitled “Unlocking the Potential of Urban Forests”, which has been the result of a huge effort of some of the world’s leading professionals and researchers in urban forestry.
The publication proposes an integrated vision for urban forestry which delivers multifunctional objectives through the involvement of diverse local stakeholders, whilst effectively responding to wide-ranging sustainability challenges and societal demands. These include the need to fight climate change, to retain biodiversity and to improve overall health and wellbeing of urban citizens through providing everyday opportunities for contact with nature. It proposes practical steps to achieve this vision, whilst considering the bigger picture of how urban forestry can be an effective tool to deliver key aspects of EU policy.

Every summer we see in the news flames burning down trees and houses, firefighters pouring water on mountain sides. In the winter we see massive windstorms blowing off entire forest landscapes. We read about very small insects that kill millions and millions of trees in few years.
In parallel, we are also observing trees becoming political in Europe. Placed at the core of many policy documents and climatic pledges, forests and their climate mitigation potential are being increasingly recognised as key in the critical achievement of European climate and biodiversity targets, as well as for the many other services they provide to society.
Media and policy attention underline that we urgently need more knowledge and sound research results on how disturbances develop, how they impact European forests and the so-called “ecosystem services” they provide, and how to respond to the seemingly increasing forest disturbance risks. A team of forest researchers from Wageningen University, the European Forest Institute and numerous research institutes across Europe investigated forest disturbances over the past 70 years and can now provide ground-breaking results in the paper “Significant increase in natural disturbance impacts on European forests since 1950” published in the journal “Global Change Biology”.

They help farmers to pick asparagus and support foresters with salvage-cutting bark-beetle damaged trees: The EU – and especially countries like Spain, Poland and Germany – is heavily dependent on so called “seasonal migrants”, either from other EU Member States or third world countries. Bringing the issue closer to home, Germany receives around 300,000 workers per year for agricultural, horticultural and forestry work, many of them from Central and Eastern Europe, especially Poland and Romania. Very often, they remain invisible. We asked ourselves, how many of these workers can we specifically find in the forest sector? What roles do they play and how can these be distinguished from the agricultural sector? How are the working conditions? And what can we do to make this issue more visible?

Forests can act as carbon sinks or emitters, as made clear by this summer’s catastrophic forest fires that ravaged southwestern France and the Iberian Peninsula. The devastating events following August’s record heatwave resulted in Europe’s highest wildfire emissions in 15 years. Only in the region of Valencia, Spain, the fires released more than 1 million tons of CO2 into the atmosphere, equivalent to the annual emissions of all private cars in the three capital cities of the province: Castellón, Valencia and Alicante.
Although climate change played a major role in the catastrophe, the fires were aggravated by rural exodus, which led to the abandonment of forest management in the area and to the accumulation of flammable vegetation, explains José Vicente Oliver, professor at the Polytechnic University of Valencia (UPV).
In cooperation with EFI, Oliver and his team are looking for ways to prepare the EU’s forests for future climate scenarios and realise their full carbon absorption potential by mainstreaming Sustainable Forest Management (SFM) into more conventional management practices. In the new Horizon Europe project INFORMA, EFI, UPV and other partners are tackling crucial questions around SFM that remain partially unanswered by science, unaddressed by policies and unexplored by most carbon offsetting schemes. How can we manage existing forests in different European biogeographic regions for enhanced carbon capture while ensuring the provision of other ecosystem services such as biodiversity conservation and wood production? Where and how should we grow new forests, and which species should be used? How can we adapt and increase forests’ resilience to more frequent disturbances such as drought, fires, windstorms and pests?
