Forest fires, field recorders, and four females

#RestorationStory by Sara Uzquiano

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. 

After a 3 hours’ drive, we finally arrived at our meeting point with Judit and Rocio, who explained to us the plan for the day. We would look for the six field recorders which were placed one week ago, transfer the recordings to the laptop and place the field recorders again in other plots of our demo area. It sounded like an easy task to do, but as we soon discovered, nothing could be further from the truth.  

The first challenge in each of them was to find the less risky entrance, as the majority of the plots are located in the middle of very steep terrain and we had to look for trees and bushes to hold on to and thus, to avoid slipping and falling while looking for the plots. And then we had to walk among the tangled forest to the center of the plot either to pick up or place the recorders.

Throughout the entire day, we were able to witness the recovery of nature after a wildfire. Our first stop was the most shocking for me. We walked on the black grass looking for the field recorders, soon our hands and boots were also black. This used to be an oak forest which suffered from a wildfire last year. The smell of burning logs could still be distinguished as if it had just been burned the day before. We pictured a landscape where it is very difficult to think a recovery is possible after all, much less any kind of life surviving in the surrounding area.

Finally, we visited plots totally recovered from the fire they suffered 40 years ago or more. Surprisingly, it was not obvious at all anymore that fire destroyed this landscape once. We could see a very diverse forest structure, with some big oak trees at the canopy level, but also small trees making their way and some natural regeneration surrounded by shrubs. This is what we, foresters, call an irregular forest, which means the trees within that forest cover the entire age spectrum, and thus, the forest presents a complex structure with trees at different levels that make it more resistant and resilience face to disturbances, and providing the perfect habitat for many special and shy species as this little viper we could see in one of the plots. We were so lucky to get to see it – vipers are endangered species and usually quite shy.

We did not realize we were a working group of four women until we stopped in a small village to replenish our energies, looking for a cup of breakfast coffee and a “Pincho de Tortilla” to eat. The moment we entered, we attracted the attention of the place, and soon, two men were not long in approaching us: “Are you on holiday?” they asked. “No. We are working.” – we replied. They could not hide their amazement and were even more curious about what we were doing. – ”Oh! As we saw you in mountain clothing on a weekday, we thought you were on holiday” they said,  as an apology, I guess. The same happened again to my colleague Patricia and I when we stopped to have lunch. The waiter could not help but approach us and directly asked how the hike was. 

Certainly, we still need to improve our understanding how ecosystems function to find the best way to help nature to build resilient forests but also, in our way doing that, we need to continue “normalizing” that four women in mountain clothing during a weekday are most probably working and not on holiday. And all this is what we are contributing to with SUPERB!

Restoring Forests, One Peck at a Time

#RestorationStory by Silke Jakobs and Ajdin Starcevic

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.

It seems that every time we visit a SUPERB demo, the sun is out. This time was no exception. We were picked up by Åsa Granberg and Johan Svensson (the Swedish demo leads) and Ruben Valbuena, our colleague from SLU. Åsa and Johan were also our personal guides for the day and took us to our first stop where forest restoration activities have been performed in 2019.  

Felled conifer trees

The restoration area was located just outside of Umeå, a popular bird-watching destination for locals. The goal of the Ume river delta restoration activities was to improve the habitat quality for the white backed woodpecker. This was primarily accomplished by removing Norway spruce and Scots pine from the site to promote the establishment and growth of broadleaved trees, primarily birch.  

As we have heard from our colleagues, the white backed woodpecker tends to avoid forests with as little as 5% Norway spruce in the species composition. It appears that some forest managers in Central Europe could learn a thing or two from a bird. But anyway, some spruce trees were mechanically felled and left in the forest to increase the amount of deadwood and favor some wood decaying fungi species, while others were girdled to become snags and provide future habitat for other wildlife. Our host, Åsa, even shared a rumor of a great grey owl making the restored forest its home.

We concluded that the restoration efforts here were a success which left us optimistic and hopeful for the restoration activities to be done on the SUPERB demo site.  

The second stop was at a possible SUPERB restoration site where the municipality has already been trying for four years to restore the forest. In 2023 it might finally happen. Marlene Olsson, one of the ecologists at Umeå municipality told us about the restoration activities which aim to improve the habitat for the white backed woodpecker. This white backed woodpecker is a national focus point in Sweden. But why is that? Can you imagine that around 200 different species benefit from creating good habitats for the woodpecker. Another national focus point in Sweden is to have more broadleaf trees and a better connection between those broadleaved areas. In the case of our SUPERB demo this implies that the conifer species alongside the riverbed will be removed. Besides a positive impact on the biodiversity our demo partners expect that this will also improve soil stability and prevent soil erosion as root systems of the broadleaves reach much deeper into the ground.  

Before continuing our trip to the next location, we needed to refuel our bodies. Åsa and Johan took us to this cozy place called the Brännlands Wärdshus. The food was delicious, it left us all speechless for a while with only the sound of a crackling fire in the corner. We could have stayed a bit longer, but there was more to be seen and daylight is scarce in Northern Europe’s winters.  

The Skatan ecopark, another of the SUPERB project’s restoration sites in Sweden was the final stop on our Sunday trip. We even had a chance to look at our previous night’s dinner in the eyes on the way there. 

Reindeer close to the SUPERB restoration sites

Reindeer herding has a long tradition in Sweden within the Sámi culture, and it represents their main livelihood. The activity is legally reserved only for the Sámi who own about 250,000 reindeer in Sweden. Climate change and intensive forest management have posed an increasing threat in recent years. Because of the nowadays shifting winter temperatures, the snow melts and freezes repeatedly even in the middle of the winter and forms an ice crust above the soil, making it difficult for reindeer to reach the lichens on the forest floor, which are a main source of food during the winter months. Moreover, the cover of ground lichens has decreased a lot (70% over a time period of 50 years) due to soil scarification and too dense forests Furthermore, because of the dense forest hanging lichens, an as important winter grazing resource, are not easily accessible. The Sámi work with forest managers to address this issue by thinning certain areas and opening up the forest canopy. This promotes lichen growth and increases the amount of fodder available to reindeer.  

Finally, we were unable to visit any of the exact locations where the SUPERB restoration activities will be carried out in Skatan ecopark because the forest roads leading there had not been cleaned. Instead, we stood on the frozen lake, with one of the sites on the other side, which allowed us to see the big picture both literally and figuratively.

One of the restoration activities, according to our hosts, will be to simulate fire disturbance, a natural occurrence that has been suppressed in recent decades. This should improve the forest’s naturalness while also supporting ecosystem services other than commercial timber and biomass production, such as recreational values and biodiversity. 

Driving back to Umeå, we could look back at another great SUPERB demo visit thanks to Åsa, Johan and Marlene. And we hope next time we visit we’ll meet one of those famous woodpeckers.
