This is an area profoundly defined by two of Galicia’s main water resources, due to their volume of water as well as their rich fauna, flora, landscape and culture: the Ulla-Deza River System, which delimits the south, and the River Tambre and its tributaries, which demarcate it in the north. Thus, it is a predominantly river area, intensely defined by the numerous rivers flowing through its municipalities, which is not surprising since Galicia is the “land of a thousand rivers”.
The characteristics of these rivers guarantee the presence of varied fauna as well as exuberant and diverse flora, made up of riverside plants and trees and colourful aquatic species, in addition to an important unknown fluvial heritage of waterwheels, weirs, millponds, trails, etc.
