Threat to Greek Fir Forests: Increasing Temperatures and Disappearing Snowtake a Heavy Toll
The Deterioration of Greek Fir Forests: A Climate Change Crisis
In the picturesque village of Kalavryta, southwest Greece, the iconic Greek fir trees, specifically the Abies cephalonica species, are facing a significant challenge. The once lush and vibrant forests are now showing signs of deterioration, with a notable decrease in healthy, green trees.
According to Katerina Kolirou, the head of the local forest service in Kalavryta, this decline is a cause for concern. The reasons behind this deterioration are complex, but they primarily revolve around the effects of climate change.
Climate Change's Devastating Impact
The global climate crisis is contributing to the difficulties faced by Greek fir forests. Average temperatures in Greece have been rising, with some mountain regions seeing a 2°C increase between 1991 and 2020, as reported by Kostas Lagouvardos, head of research at the National Observatory of Athens. This upward trend is not unique to Greece; globally, 2024 was the hottest year on record.
These rising temperatures, combined with prolonged droughts, are putting immense pressure on the Greek fir trees. The warmer and drier conditions stress the trees, reducing their growth and increasing mortality rates. The firs’ needles become brittle and discolored, indicating stress and dieback.
Another factor exacerbating the situation is the decrease in snow cover. Snow acts as insulation during winter, protecting the roots of the trees from the harsh cold. However, with declining snow due to warming, the roots are exposed, further stressing the trees and weakening their health and resilience.
Pest Infestations: A Deadly Consequence
The stressed and weakened trees are becoming more vulnerable to pest infestations. Dimitrios Avtzis, a forest entomologist with the Greek Agricultural Organization Demeter, has stated that these beetles cause significant damage to the trees by burrowing into the bark and impeding the flow of nutrients.
Scientists and locals report drought-linked vulnerability to pest outbreaks in Kalavryta and the broader region. Removing dead and infected trees may not be sufficient to prevent the spread of pests.
The Broader Implications
The deterioration of Greek fir forests is not exclusive to Greece. The Mediterranean region is experiencing similar issues, highlighting a regional trend of forest vulnerability. The loss of fir forest cover contributes to shrinking forest areas and loss of biodiversity, reducing the capacity of these ecosystems to absorb CO2, undermining climate mitigation efforts and EU climate goals.
Forest loss disrupts local ecosystems, potentially leading to soil erosion and decreased water retention. Socioeconomically, forest degradation affects local communities dependent on forestry and related tourism, though detailed social impacts in Kalavryta are less documented in the current results.
The Need for Action
Swift action is necessary to address the underlying causes and preserve what remains of the Greek fir forests. Artificially creating snow as an alternative is impractical. Instead, efforts should focus on mitigation measures, such as reducing greenhouse gas emissions, promoting sustainable forest management, and supporting reforestation initiatives.

- Research conducted by Katerina Kolirou, head of the local forest service in Kalavryta, shows that the decline in the Greek fir forests is a significant concern, with environmental science indicating a primary cause to be the impacts of climate change.
- In her article, environmental journalist Sarah Tancredi emphasizes the importance of ESG reporting on climate change, particularly focusing on the devastating impact on green health-and-wellness ecosystems like the Greek fir forests, and the need for effective therapies and treatments to combat such crises.
- Students taking environmental-science courses may find it intriguing to delve into the science behind climate change and its role in the deterioration of forests, as showcased by the ongoing crisis in Kalavryta, where climate change is leading to pest infestations.
- As noted by Kostas Lagouvardos, head of research at the National Observatory of Athens, the global report on climate change indicates a trend of increasing temperatures, which is placing a great deal of strain on not only Greek fir forests but also many other ecosystems worldwide.
- To help curb the effects of climate change, organizations and communities can engage in initiatives focusing on reduced greenhouse gas emissions, sustainable forest management, and reforestation, as outlined in the European Commission's white paper on climate change mitigation and forests.
