DRY STONE WALLS
To the right of the path are dry stone walls, evidence of a recent agricultural past and a habit of making maximum use of the land, which was present in much of Catalonia until the middle of the twentieth century. These structures slow loss of rainwater, as well as retaining humidity and preventing erosion.
One of the most important contributions of drystone walls is their great importance for wildlife. The presence of a large variety of insects is also worth noting. These were very important for controlling infestations and pollinating crops.
Because of the way drystone walls retain heat, they are very useful for many reptiles like the ocellated lizard and the common wall lizard.
