Regional Park of the Middle Course of the river Guadarrama and its surroundings
In the western area of the Community of Madrid we find this natural space of great environmental diversity. From the base of the Madrid mountains to the countryside of the Tajo depression, following the course of the Guadarrama and Aulencia rivers, it presents three main landscapes in its territory: the Mediterranean forest, the riverside forest and the crops or wastelands. The Regional Park of the Middle Course of the Guadarrama River and its surroundings is a protected natural area of the Community of Madrid (Spain), located in the western part of the region. It extends from the municipal term of Galapagar (at the height of the Las Nieves reservoir) to that of Batres, on the border with the province of Toledo. It is configured as a long and narrow strip, around the banks of the Guadarrama River, about 50 km long, following a North-South axis. In its northern part, the strip widens to integrate part of the course of the Aulencia River, the main tributary of the Guadarrama. The Regional Park protects approximately 38% of the course of the Guadarrama, whose total length is 131,8 km. Demographic pressure, derived from the existence of numerous urbanizations in the vicinity, some on the very edge of the riverbed, constitutes the main threat to this protected natural area.
