Tenerife Wildfire Investigation Stalls One Year After Devastating Blaze

The scars left by the August 2023 wildfire on Tenerife serve as both a stark reminder of the island’s climate vulnerability and a troubling example of how environmental crimes often go unpunished. One year later, the investigation into the blaze that started in the mountains of Arafo and Candelaria remains stalled, with no one held responsible for the fire that triggered the catastrophe.

The fire, which broke out on the night of August 15, was a turning point for emergency management on the islands. Classified as a "sixth-generation" blaze, its intensity was fueled by extreme weather—high temperatures, low humidity, and unpredictable winds—that pushed local institutions to their limits. For nine days, a massive coordinated effort involving the Canary Islands government, the Military Emergencies Unit (UME), and local teams battled a 90-kilometer fire perimeter, forcing more than 12,000 people to evacuate their homes.

The environmental impact was severe, affecting 7% of the island’s total land area, including ecologically vital regions like Teide National Park and the Corona Forestal Natural Park. While the fire was stabilized on August 24 and officially extinguished by November 10, 2023, the damage remains visible.

Nature is recovering, but at an uneven pace. While the native Canary Island pine has shown resilience by resprouting, more fragile ecosystems, such as the laurel forests and summit vegetation, are struggling to bounce back. Experts from the CSIC estimate that it will take three to four decades for the 14,000 scorched hectares to fully recover. This long road to regeneration highlights the urgent need for better fire prevention and more effective legal action against those responsible for these incidents, which remain one of the greatest threats to the biodiversity of the Canary Islands.
