The Age of MegaFires

Wildfires have been constantly increasing in scale and level of damages, affecting vegetation, protected sites, and destroying valuable and vulnerable habitats and species in Europe. Between 2015 and 2025, large wildfires have shifted from being outliers to a regular feature, a pattern that became even more visible from 2021 onwards.

An EDJNet investigation coordinated by MIIR analysed how illegal megafires turned into a new normality for Europe, and what kinds of impact does this have on protected ecosystems, mixed lands, and what can be done by states to face this emergency.

Main findings:

  • In the first half of the timeframe analysed in this investigation (2015-2020) large wildfires were still exceptional, with the significant case of the 2017 season in Portugal, when 26 fires were larger than 5000 hectares.
  • The wildfire monitoring system implemented by the European Commission (EFFIS) shows that Europe’s fires target a small number of regions, mainly in rural areas, and target mostly shrubland and transitional woodland.
  • 2025 was the second most destructive wildfire season since monitoring began, in 2000. In total, 18 megafires (above 10,000 hectares) occurred in Europe in the span of just a few months.
  • Nearly 1,3 million hectares of burned land overlapped with Natura 2000 protected land, a network of protected areas to preserve endangered species and habitats in the European Union. The most affected countries in this sense are Portugal and Spain.
  • More than three-quarters of all burned land in Europe overlaps with just 20 NUTS-2 regions, the administrative scale used to coordinate regional forest policy, climate adaptation, and wildfire preparedness. Portugal, Spain, Italy, Greece and Croatia are the countries where these 20 regions are located.
