Introduction

The important historical and biological value of the dry stone walls is undeniable. They testify to a recent agricultural past and a maximum use of the land, valid until the middle of the twentieth century in much of our territory. These constructions allow to restrain the drainage of rainwater, as well as to retain moisture and prevent erosion of the terrain.
In addition, these dry stone walls are also important for the ecosystem, given the living beings that grow there. The most characteristic of these dry stone walls are lichens, mosses and ferns. It also highlights the presence of a large variety of insects, which were of great importance for the control of pests and the pollination of crops. On the other hand, thanks to the heat that retains the dry stone, these walls are very useful for many reptiles, such as the common lizard. You can also find mammals, such as the common mouse and the shrew.
