The changing climate is posing a significant threat to forests in Italy’s mountainous regions. Ongoing research suggests that these forests are becoming increasingly vulnerable, and the composition of future forests may undergo dramatic transformations. The familiar tree species currently found in European forests could either disappear or migrate to higher elevations.
A recent study published in Frontiers in Forests and Global Change has focused on five susceptible mountain regions in Italy to analyze and project the potential evolution of these delicate ecosystems in response to environmental changes. Dr. Sergio Noce of the Euro-Mediterranean Center on Climate Change Foundation (CMCC) emphasized the gradual nature of this species shift, highlighting the need for time and understanding in the face of this natural process.
Forests play a crucial role in supporting communities by providing valuable resources such as wood products and wild foods like truffles. They also impact water availability and quality, maintain soil, preserve biodiversity, and offer recreational opportunities. Although approximately one-third of Italy is covered by forests, recent years have seen them facing damage from droughts, storms, and fires, leading to rapid environmental changes. Mountain forests, in particular, are highly susceptible to the climate crisis.
To comprehend and address these challenges, accurate climate data and reliable predictive models are necessary to project the future implications of the climate crisis on these vulnerable forests. Noce and his team developed species distribution models for forests in various areas, incorporating climate change projections based on different emission scenarios. This data was used to create maps indicating the suitability of land for future tree growth up to 2050.
Understanding how different species will be impacted by changing conditions is crucial for planning, management, and conservation efforts. Noce stressed that forests provide essential ecosystem services, including water cycle regulation, biodiversity preservation, wood and non-wood product provision, tourism support, carbon capture, and storage. Decisions made today will have far-reaching consequences for these services, making informed choices imperative.
The study’s findings revealed that most species are likely to see a decrease in their suitable range, while some may extend beyond their current habitat, notably the European larch and Turkey oak. This trend was observed under both emission scenarios, with varying degrees of change. Overall, the tree line is expected to shift to higher elevations, potentially leading to the loss of species with specific range requirements. High mountain ecosystems like alpine meadows may also become scarcer as trees encroach on these areas.
While it’s challenging to identify clear winners or losers among the studied tree species, the silver fir and European beech are particularly vulnerable. Among the five regions examined, the northern and north-eastern Apennines face the greatest risk, with all existing tree species vulnerable to change. The study emphasized that mixed stands of trees with diverse species are more resilient.
However, the introduction of survivor species could introduce new vulnerabilities. For example, the Maritime pine, a candidate for bolstering forests in the southern Apennines, is more prone to fire than the currently prevalent tree species. As the risk of wildfires is expected to increase, this could pose significant challenges.
The authors cautioned that the relationship between environmental variables and species presence may not remain the same as in the past, and change could still hold surprises. Nevertheless, these high-quality models serve as valuable tools to identify species and forests that could potentially withstand the impacts of the climate crisis.
Dr. Noce expressed plans to expand and deepen this research in Italy, thanks to funding from the European Next Generation EU program. The goal is to extend the geographical scope and time horizon of the study, continuing efforts to better understand and address the challenges facing Italian mountain forests in a changing climate.

Frequently Asked Questions (FAQs) about Italian Mountain Forests
What is the main impact of climate change on Italian mountain forests?
Climate change is causing significant alterations in Italian mountain forests, primarily by affecting tree species and ecosystems.
How are tree species in European forests responding to climate change?
Many tree species in European forests are either vanishing or moving to higher altitudes due to the changing climate.
What were the key findings of the research study on Italian mountain forests?
The study focused on five vulnerable mountain regions in Italy, revealing that most tree species are likely to experience a decrease in their suitable range, while some may extend beyond their current habitat. This shift is expected to result in a higher tree line and potential loss of species with specific range requirements.
Why are mountain forests particularly susceptible to the climate crisis?
Mountain forests are especially vulnerable to climate change because they face increasing threats from factors such as droughts, storms, and fires, which can rapidly alter their environmental conditions.
What is the significance of diverse tree stands in mitigating the impact of climate change on forests?
Diverse tree stands with a variety of species are more resilient to environmental changes. They can better adapt to shifting conditions, helping to maintain biodiversity and ecosystem services.
How can this research contribute to better forest management?
The research provides valuable insights into which tree species may be advantaged or disadvantaged by future climate conditions. This information is crucial for planning, management, and conservation efforts to protect the ecosystem services provided by forests.
What are the potential challenges posed by survivor species in these changing ecosystems?
Survivor species, while adaptable, can introduce new vulnerabilities, such as increased fire risk. The introduction of species with different ecological traits may have unforeseen consequences.
Are there plans to expand and continue this research?
Yes, the researchers plan to expand the study both geographically and temporally. They intend to deepen their research in Italy and extend the time horizon, thanks to funding from the European Next Generation EU program, to further understand and address the challenges facing Italian mountain forests in a changing climate.

Italy’s mountain forests takin’ a hit, bracin’ for big changes. Research says we need diverse trees _xD83C__xDF33__xD83C__xDF32_ for survival. Climate’s a tough cookie!
Sad to see forests in trouble _xD83D__xDE22_. Hope they figure out how to protect ’em. We need those trees for a lot of things, not just wood! _xD83C__xDF33_❤️_xD83C__xDF0D_
Dang, climate changin’ the game for Italian forests. Could hurt wood products, economy _xD83C__xDF32__xD83D__xDCB0_. Gotta think long-term, plan better. _xD83E__xDD14__xD83D__xDCA1_
wow, this is a big deal, climate change messin’ up Italian mountain forests. tree species gone wack, some movin’ higher! _xD83C__xDF32__xD83C__xDF0D_
