The Threats

Farmland abandonment and a lack of native grazers has allowed the Portuguese broom (Cytisus striatus) to take over the mountainside. In the summer, this tall shrub dries up and becomes the perfect fuel for Portugal's wildfires. In a landscape that deals with the reality of regular fires, with a natural wildfire expected every 8-12 years, this poses a very real threat to local populations. It also hinders the regeneration of the fire resistant oak woodlands.

The native oak trees are more resistant to these wildfires, and could ultimately spread across the mountainside, but the process would take too long, around 100 – 150 years. The current shrub vegetation that covers the landscape burns intensely fast, which makes it impossible for firemen to manage. This means wildfires can quickly get out of control and pose a threat to local people.
