Project summary

Edit project overview to modify the project summary.


The morphological restoration project area is located in a Natura 2000 site, in the monastery of Santes Creus, a scenically and symbolic landmark. The whole project will pursue conservation objectives set forth by the Plan of Catalonia natural areas and enhancing the natural, scenic and social basis for the declaration of the Grove of Santes Creus as an Area of Natural Interest. The main actions in this project are: demolition and removal of the rubble to recover geomorphological processes characteristic of stretch and lateral and vertical connectivity of the same; geomorphological reconstruction of the section; Improvement and restoration of habitats; elimination of exotic plants, as Tradescantia fluminensis or Phytocala americana. The project has a total budget of 43.550.476 € and is financed by the ACA (Agencia Catalana del Agua) and Tarragona Provincial Government.
