When forests thrive: nature conservation, culture and change in Friuli Venezia Giulia 

Blogpost by Gesche Schifferdecker

What happens when forests are left to develop naturally? How does wildlife influence forest regeneration? And what do we gain and lose when forests reclaim land that was once managed by people?

As part of the Wildcard project, in collaboration with the University of Udine, we went on a two-day study trip to explore these questions across two fascinating – and very different – Wildcard case study sites in the Friuli Venezia Giulia region of Northeastern Italy.

On the first day, joined by more than 20 forest managers, researchers, forestry experts and representatives of different associations, we explored how ecological processes, historical land use and local traditions continue to shape the region’s forests and landscapes.

Old forests, new insights

Our first stop was the Cansiglio Forest, where we visited stands displaying impressive old-growth characteristics. Researcher Antonio Tomao introduced us to the ecological processes unfolding in forests that have been left to develop with minimal human intervention. The Pian delle Stele reserve has been established in the early 1970s, with the last management intervention taking place more than 60 years ago, allowing natural processes to shape the forest over several decades.

The landscape offered plenty to discover: abundant deadwood, fascinating fungi, tree cavities and a remarkable variety of microhabitats. Natural disturbances create structural diversity, providing essential habitats for species that depend on mature trees and decaying wood, including rare beetles and fungi. These features remind us that a forest’s ecological value extends far beyond the number of living trees it contains. It was beautiful to see how impressed and proud the participants were, for example when we found a Hericium erinaceus, a rare fungus that only grows on deadwood. Every 200 meters we had to make a break, both for the experts to explain the diverse forest features, as well as for the group to take several photos. From researcher Guido Marcoz we learnt that the group of scientists from University of Udine has found rare woodpeckers and a small owl, that only nests in holes that were formerly occupied by woodpeckers. What an excitement the researchers must have felt identifying these species with on-the-ground data collection techniques like sound recording – it was still visible when listening to Guido. “These species need a lot of deadwood”, Guido stated, and we learned that “by leaving standing and laying deadwood to decay also in forests managed for wood production, it is possible to promote these habitats as well”.

While hiking through the wild and steep forest, we also explored how old-growth forests contribute to carbon storage and sequestration, and how biodiversity develops as forests mature. One particularly interesting question was how these forests respond to climate change. While their structural complexity and natural processes offer valuable insights into forest resilience, understanding their long-term responses remains an important research challenge.

“We need to make the people aware of the different forest functions, and that there can be conflicts of interests depending on which function is prioritized”, said forestry advisor Fabio Cogo. He also mentioned that – apart from carbon credits – there are very few options to get funding for setting forests aside for conservation purposes, and that this funding is usually only beneficial for a small group of stakeholders.

How forest development is shaped by wild animals

Yet natural forest development does not happen without pressures. Deer browsing, for example, can significantly limit natural regeneration and reduce the diversity of tree species. At our second stop, we saw a striking illustration of this challenge, presented to us by forest manager Roberto Luise, the local forest manager. An area protected by fencing for 15–20 years showed a remarkable difference in regeneration compared with the unfenced forest across the road, where young trees were scarce and shrubs dominated. We also discussed the potential of hunting – which we learnt is not allowed in the area – and the option of re-introducing the wolf. Roberto stated that the wolf plays an important role in addressing the game situation, “but it cannot be the only solution”, added Roberto. Seeing the effects of browsing on forest regeneration was a powerful reminder that natural processes are shaped not only by the management – or the absence of it – but also by the presence of wildlife and the conditions surrounding the forest.

Local communities as a key to success?

From Federica Biondo we learnt that there is still a lot to do in terms of taking local communities onboard, raising both their awareness and support for the local forests and their benefits. This is why her organization  Legno Servizi, supporting the forest-wood sector in the Friuli Venezia Giulia region, has recently established forest education centers in both Udine and Triest. These were founded to contribute to their main objective, promoting sustainable forest management and the use of local wood through a range of dissemination, research, communication and project development activities.

Finally, in the evening, after most of the participants went home, we met Giulia Zanuttigh in Udine, about 2 hours away from Cansiglio forest. Giulia is a member of the Italian Alpine Club and works at the Municipality of Udine. She emphasized that local people should have an influence on what is happening with the forests near their homes. This could involve being allowed to cut forests to use the land as a meadow, as was done in the past. She also sees potential for more tourism, but less related to forests and their biodiversity but more related to the cultural use of forests and land.

When the forest returns: a visit to Soffumbergo

On the second day, we turned our attention to Soffumbergo, a landscape that tells a different story of forest change. Around 80 years ago, much of this area consisted of open meadows and pastures. Following the devastating earthquake of 1976, many residents left their villages, and agricultural land was gradually abandoned. Forests subsequently reclaimed these open spaces, with species such as maple, ash and hornbeam establishing themselves under the region’s favourable growing conditions.

Today, tall trees, woodland habitats and signs of wildlife reveal the ecological opportunities created by this transformation. At the same time, the expanding forest tells a story of disappearing cultural landscapes. Traditional agroforestry systems, including meadows dotted with chestnut trees, once supported local livelihoods and shaped the identity of the villages. Their decline means losing not only familiar landscapes, but also traditional knowledge, land-use practices and elements of local cultural heritage.

Between rewilding and cultural landscapes

Managing these changing landscapes is further complicated by fragmented land ownership. Some parcels are extremely small, ownership records are outdated, and identifying the people responsible for abandoned land can be difficult. Local initiatives like “Pro Loco” are therefore exploring ways to coordinate land management, maintain open areas near villages and restore selected meadows where this can support cultural values, tourism and landscape resilience. One engaging example we learned about was the “Chestnut Festival”. This event is organized by Pro Loco in the small village Valle di Soffumbergo, which has around 10 inhabitants, but several hundred visitors for the Festival. At the heart of the village, we met Giorgio Dri, who told us about the history of the area, and about the impacts of the land abandonment. He emphasized that the impressive nature is attractive for ecotourism, and proudly shared that they organize different activities with tourists throughout the year. These include for example forest bathing and an excursion to the forest in the night of San Lorenzo on 10th August, where visitors can see the shooting stars at night, and are welcomed back to Soffumbergo with a “Pasta asciutta” at midnight. However, with wildlife being so close to their houses, he also expressed his concern regarding wild boars, destroying the local gardens.

Our final stop, at the aptly named “Meadows of the Church”, offered another striking perspective: a place where open land is increasingly being taken over by forest. We realized that the only meadow left there – most likely the place where visitors watch the shooting starts – might also been taken over by forests in the next years.

Across both days, one message became clear: forest change is never just an ecological story. It is also a story about history, livelihoods, biodiversity, climate, ownership and the relationship between people and their landscapes. And Rewilding does not represent a universal solution, but rather a set of context-specific strategies whose success depends on the ability to manage ecological, economic and social conflicts at local scale, integrating restoration interventions and natural dynamics with the needs of local landscapes and communities.

The Wildcard study trip provided a valuable opportunity to exchange perspectives, learn from local experience and reflect on the choices facing forest managers today. Rather than asking whether intervention or non-intervention is always the right answer, these landscapes invite us to consider a more nuanced question: what kind of forest and landscape do we want to sustain, and for whom?

Wildcard study site recognised as one of Italy’s first old-growth forests 

Pian de le Stele, one of WILDCARD’s proforestation study sites in the Cansiglio Forest, has been officially recognised as an old-growth forest and is now included in Italy’s National Network of Old-Growth Forests. 

Located in the municipality of Polcenigo, in the Friuli Venezia Giulia region, Pian de le Stele is among the first forest stands in Italy to receive this recognition. Together with Bosco Vintulins and Croseraz-Val Bona, it was formally included in the national network following ministerial decisions on 6 August 2026. 

Protected as an integral reserve since 1971 and free from timber harvesting for more than 60 years, the 14.36-hectare silver fir forest provides an important example of long-term natural forest development. Surveys carried out by researchers at the University of Udine have documented characteristics associated with mature forest ecosystems, including large trees, substantial carbon stocks, abundant standing and lying deadwood, and a diversity of tree-related microhabitats supporting numerous species. 

Pian de le Stele also has a direct connection to WILDCARD. The site is part of the project’s network of research sites and contributes to our work investigating proforestation – the process of allowing existing forests to continue growing and develop naturally by reducing or suspending forest management interventions. 

Being included in Italy’s National Network of Old-Growth Forests is therefore an important step towards protecting the site in the long term. It also highlights the ecological value that forests can develop when natural processes are allowed to continue over time. 

The recognition follows research led by the University of Udine’s Department of Agricultural, Food, Environmental and Animal Sciences, coordinated by Wildcard coordinator Giorgio Alberti, as part of a wider study promoted by the Forest Service of the Friuli Venezia Giulia Region.

Karst ecosystems from 2022 to 2024: what changed after the big fires

A new investigation by the Universities of Udine and Trieste shows the effects of rewilding on Karst ecosystems between Italy and Slovenia after the large 2022 fires. The research results were shared in a conference organised by Italy’s National Biodiversity Centre, funded by the National Recovery and Resilience Plan, and WILDCARD.

—

The 2022 Karst fires between Italy and Slovenia led to the loss, on average, of almost 50% of the biomass present in the area affected by the fire, with considerable differences depending on the composition of the forest. The fires were also favoured by the dry plant biomass accumulated following repeated dry summers. The forest, however, is already regenerating massively.

As far as animals are concerned, since the spring following the fire, burnt areas have been used intensively for food by some species of herbivores such as roe deer and hares, and less so by deer and wild boar, which are, however, increasing strongly in the non-fire areas. The various bird communities in the burnt areas also show changes compared to those in the non-affected areas.

These are some of the main results of the surveys carried out by the Universities of Udine and Trieste, with the support of Legambiente volunteers, on the territory affected by the fires that almost two years ago incinerated about 4,100 hectares of forest area between Italy and Slovenia. A balance of the situation was made on the 1st of March in the Italian town of Gorizia with the conference “Rising from the ashes? Ecological and management consequences and prospects of the 2022 Karst fire“. Speakers included scholars from various disciplines of the two universities and technicians from the Friuli Venezia Giulia Region’s Forestry Corps.

The forest and biodiversity – By combining ground measurements with satellite surveys, it was possible to quantify the extent of damage to the forest and the post-event reaction. The greatest damage was found in areas dominated by scotanus and manna ash, while downy oak showed greater resistance to fire. However, the forest is already vigorously reproducing through stump regrowth and seed regeneration, particularly where the fire intensity was lower. The specific post-fire composition is closely linked to the intensity of the event. The data, presented by Giorgio Alberti and Francesco Boscutti of the University of Udine, ‘show that species richness increases linearly with the latter, regardless of whether native or allochthonous (exotic) species are taken into account’. In addition, thanks to the surveys carried out, it was possible to investigate in detail the adaptive strategies implemented by the different species in regaining space after the event, highlighting functional traits that are profoundly different depending on the species and the characteristics of the environment after the fire.

Mammals – Specific research is currently underway to assess the presence and use of burnt and unburnt areas by medium and large mammals and their behaviour. Initial results show very dynamic and specific processes in different areas and for different species. In the spring following the fire, the burnt areas were used with great intensity by some herbivore species such as roe deer and hares for food, and less so by deer and wild boar, which nonetheless show a strong increase especially in the non-fire-affected areas. The golden jackal, a typical species of this area, where it shows very high densities, appears to be more present in the non-fire areas, although a few months after the fire it had shown an apparent increase in the frequentation of the area affected by the fires. For this species it seems interesting to understand the phenomenon that has affected the Gorizia karst, where there was a sharp increase in mortality from road and rail accidents in 2023, and whether or not this can be directly or indirectly linked to the large fires of 2022 and/or other factors The different areas compared in terms of the structure and composition of tree species, type of undergrowth and intensity of the fire they have suffered, show their own specific dynamics in terms of the presence of animals, as well as the behaviour of the animals detected with the phototraps.

The Friulian University’s Fauna Management and Conservation research group has been carrying out research on mammals in the area of the Gorizia and Trieste Karst for over ten years. “In this context,” explains the group’s coordinator, Stefano Filacorda, “the great fire of 2022 provided, in the dramatic nature of the event, an opportunity to study and compare the dynamics of the presence and behaviour of many mammal species present on the Karst”.

Habitats – Through the processes of ecological succession, fire-affected habitats can reconstitute themselves spontaneously, but climate change and the expansion of exotic and invasive species can lead to a change in the floristic composition, characteristics and dynamism of habitats. This is what emerged from the first monitoring results developed to analyse the consequences of fires on the species composition and dynamic processes of the main Karst habitats presented by Miris Castello from the University of Trieste.

Water in vegetation – The possibility of estimating the water content of vegetation remotely is fundamental for monitoring the risk of fire propagation on a large scale. In the Karst region, the NDWI index obtained from satellite images – which uses infrared wavelengths to monitor changes in the water content of leaves – was found to be correlated with water content measurements taken in experimental areas. Thus, Francesco Petruzzellis, from the University of Trieste, pointed out that ‘the development of a model for predicting the water content of vegetation specific to the Karst area could be a relevant tool for determining fire risk during dry periods’.

Woody species and fire risk – The fires of 2022 were favoured by dry vegetation biomass accumulated following repeated dry summers. The analysis of the water stress tolerance of the different native and invasive woody species present on the Karst, combined with the characterisation of the flammability of their biomass at different water contents, makes it possible, explained Andrea Nardini, of the University of Trieste, “to identify the level of fire risk associated with the presence and abundance of each species in future climate scenarios”.

The consequences on ornithological communities – Almost two years after the fires, the ornithological communities of the Italian and Slovenian Karst show changes compared to those present in non-affected areas. Davide Scridel from the University of Trieste explored which biological and ecological characteristics of each species may determine their position as ‘winners’ or ‘losers’. “Although burnt areas host fewer species and individuals,” Scridel said, “the effects vary between different species and habitats.

The contribution of the Forestry Department – The Regional Forestry Department of the Friuli Venezia Giulia Region operates at various levels in the regional system of forest fire protection. Dario Cancian, of the Regional Forestry Service and Corps of Foresters, explained that its operations “are not limited to the so-called ‘active fight’ against fires, but include forecasting and prevention activities, implemented through surveillance, land management, the granting of contributions and investigative actions. The survey of areas covered by fire and the collection of numerous data related to the events that occurred also contribute to research and statistical processing of the phenomenon’.
