Project summary

Edit project overview to modify the project summary.


This intervention is part of the LIFE RISORGIVE (LIFE14 NAT/IT/000938) “Conservation of biodiversity in the Municipality of Bressanvido”. The general objective of the LIFE RISORGIVE is for the reinstatement and consolidation of the green infrastructure that consists of a network of resurgences, irrigation ditches and channels in the Bressanvido District (Vicenza– Italy). This infrastructure is located in an area with a strong agricultural (dairy farming) orientation: within this context the loss of biodiversity caused by the intense exploitation of the territory can be significantly reduced. LIFE RISORGIVE includes 26 resurgence systems (a total of 43 springheads) that have already been identified by a previous census, their banks, irrigation ditches and connected waterways. The restoration of the 26 resurgences involves stakeholders who an essential role in their protection and enhancement such as land reclamation authority, farmers, ecological associations, fishermen.

Specifically, the interventions envisaged for the environmental requalification for the "Roggia Girosa" project are: (1) Construction of structures that encourage people to use the Girosa spring for tourism / educational purposes such as: creation of a new path for visiting the spring and the Girosa canal to be built partly in the left hydraulic part and in the right hydraulic part, parallel to the path of the irrigation ditch, by laying, where necessary, gravelly background material with a stabilized finishing layer and vertical signage of the path consisting of wooden poles and signposts; construction of wooden bridges, with any protective barriers, to allow people to walk and move during the visit to the spring, and to allow the crossing of the canal from the hydraulic left to the hydraulic right side and vice versa; (2) Hydraulic and morphological restoration and redevelopment interventions (Morphological redevelopment: reshaping and re-profiling of the banks; Installation of deflectors, constrictors and stones and boulders inside the resurgence (3) Vegetation redevelopment interventions (Restoration and arrangement of the bank vegetation planting native species suitable for the resurgence environment, Restoration of natural habitats such as wet, temporary and permanent areas); (4) Creation of didactic panels and signs.
