In this section of the route, we cross a denser and better-preserved holm oak forest, which serves as a true refuge of biodiversity and a living example of the Mediterranean ecosystem in its most mature state. The holm oak (Quercus ilex) is the dominant species, forming a canopy that allows for the existence of a diverse undergrowth where species such as French lavender and rosemary thrive, along with numerous grasses.
This environment provides food, shelter, and breeding grounds for many animal species such as wild boar, badgers, and foxes. Among birds, species like the tawny owl, hoopoe, and tits also find suitable habitats here. In addition, the holm oak forest plays a significant ecological role by acting as a carbon sink, promoting water infiltration, and conserving soil, thus contributing to climate change mitigation.
