Project summary

Edit project overview to modify the project summary.


Tordera River passing through Sant Celoni, boxed in between the AP-7, to its right bank, and industrial parks and estates, to his left side, presents a high state of degradation. These interventions in the territory have altered the natural course of the river and caused the loss of habitats within the area. In these latter interventions we must add the intensive use floodplain for agriculture, livestock, crops poplar and aggregate extraction. The main objectives of this project are: To improve the structure and composition of the vegetation; landscape integration of rip-raps; Creation of refuge and breeding ground for otters and awareness campaigns.
