The Landes de Gascogne, perceived as a natural forest, is actually a human-made pine plantation born from a 1857 engineering gamble that now faces ecological challenges.
Historical forest created by human effort
The Landes de Gascogne, often seen as a natural forest, was actually created by human intervention in the mid-19th century. A law passed in 1857 aimed to transform the region's marshy land into a productive forest through drainage and the planting of maritime pines.A unique forest structure
Today, the Landes forest spans nearly one million hectares, with 92 percent of its area covered by maritime pines. Most of the forest is privately owned, a legacy of the original economic plan that focused on timber production.The risks of a monoculture
The dominance of a single tree species has made the forest vulnerable to environmental shocks. After the storm Klaus in 2009, millions of cubic meters of pine trees were destroyed, leading to widespread damage and the spread of bark beetles that further weakened the forest.Recent environmental disasters
In July 2026, the Landes region faced its most severe wildfires in decades, highlighting the risks of a uniform forest. These fires, like the storm before them, showed how a lack of biodiversity can increase the forest's susceptibility to natural disasters.Efforts to restore diversity
In response to these challenges, current efforts focus on preserving some of the original wetlands and increasing the presence of broadleaf trees. These changes aim to break the continuous growth of pines and reduce the risk of future disasters, even as the maritime pine remains a key economic resource.
