LIFE+ NAT/IT/000413 P.A.R.C. “Petromyzon And River Continuity”
Short description of the intervention
In light of the LIFE P.A.R.C. project, the NBS here presented consisted in the restoration of the fluvial and ecological continuity of the Magra and Vara rivers in the Montemarcello-Magra Regional Natural Park. The intervention implemented the removal of artificial barriers blocking the water continuity currently affecting biodiversity conservation. In the meantime, several activities implemented focused on restoring the area along the stream with the creation of walking paths and the use of signs to spread environmental awareness about the key habitat provision services of the area (1).

Goals of the intervention
The main objective was the creation of nine fish passes to overcome significant obstructions to migrating fish reaching their natural reproduction areas, even those species attempting to swim upstream in low water flows (1 and 2).
Quantitative targets
"The beneficiary planned to extend suitable migratory fish reproduction areas by 59 ha and increase the area of habitat specifically suitable for the development of sea lamprey ammocoetes (the burrowing blind larval stage) by nearly 15 ha" (1).
Monitoring indicators defined
The monitoring indicators identified is the observation of the migration and reproduction behaviour of the local fish species (4 and 5).

Implementation activities
Eight passages for fish were constructed on the dams. Four fish ramps were installed on the river Magra and another four along the river Vara. River continuity was established for about 50 km. Flood damage at one project site demolished a boulder dam, so boulders had to be replaced. Additional work also led to improved river quality through the placing of large boulders in the river bed and the constructing of breakwaters with boulders or vegetation, in order to diversify the banks and the current, and the planting of autochthonous plant species" (1). A detailed overview of the many actions is available on the official website and the final report (2 and 3).

Impacts, benefits
Description of environmental benefits
The monitoring data showed clearly the positive impact of the fish ramps. There was a hundredfold increase in the number of Sea lamprey reproduction sites, as evidenced by the presence of ammocoetes (larvae). Twaite shad were observed 19 km beyond the location registered at the projet start (41 km from the sea); reclimbing of twaite shad had never been observed in this upper part of the Vara river before the installation of the fish ramps" (1 and 3).
Creation of 4 river observation areas equipped for the awareness raising of local populations as well as for monitoring and surveillance operations for a total of 4.400 sqm and 1.870 km;
Restoration of the hydraulic and biological continuity of the Magra and Vara rivers through the realization of 8 fish-passages and the adjustment of the barrier located in Madrignano (VR05), for a total praticability of about 50 km of watercourse; (6)

Comments and notes
Additional insights
"The Montemarcello-Magra Park contains the only Italian rivers in which successful reproduction of the Sea lamprey (Petromyzon marinus) has been seen: the Magra and Vara rivers. These rivers also host many other important migratory fish species of European Community interest, both those migrating between seawater and freshwater (diadromous) and those migrating within the basin during the reproductive period, including Twaite shad (Alosa fallax), Western vairone (Leuciscus souffia), South European roach (Rutilus rubilio) and the Italian barbel (Barbus plebejus). However, artificial obstructions, such as boulders and dams, have interrupted the natural continuity of the river and fragmented fish populations, preventing some fish species from migrating to their natural reproduction areas when the river is low. As the fish, including Sea lamprey, are forced to reproduce in parts of the river unsuitable for the development of their eggs, successful reproduction has significantly declined. This represents an important threat to riverine fish species" (1).

"SCI IT 1343502 Parco della Magra – Vara is the last significant example of river environment in Liguria.
Perhaps unique in Italy is its role of ecological corridor between the Mediterranean bio-geographical and
continental regions which makes it essential to the conservation of various aspects of biodiversity in
northern Italy" (3).
