Project summary

Edit project overview to modify the project summary.


In the Serpis River there are a variety of habitats, from riparian forest with undamaged stretches to Mediterranean forest. There are also elements of great cultural and heritage value, as mills from the XIX century. Anthropic pressure, mainly agriculture and hydropower industry makes necessary the restoration to ensure the ecological river corridor. The actions of the project are: Recovery of the river mobility space; Recovery of river morphology: recovery of the steepness of the slopes of the channel and the original path of the river (oxbow connection); Recovery of longitudinal continuity: demolition of 5 obsolete weirs and construction of fish ladders in two weirs; Clean channel and its banks; Elimination of exotics plants, silvicultural treatments and planting of riparian trees and shrubs; and installation of information panels and limitation on use of roads. The project has a total budget of 6.912.492€ and is financed by the Ministry of Environment, as part of the National Strategy for River Restoration.
