Project summary

Edit project overview to modify the project summary.


The area of intervention is indeed a strip of territory, which for historical reasons and geographical conditions, has been relatively little used and so it was particularly intact. For these characteristics, in this particular area have been identified seven SIC showing the particular concentration of species and habitats priority.

Unfortunately, in recent years occurred excessive use of resources and environments and abandonment and neglect of large portions of land that have caused serious degradation phenomena (pollution of water, simplification of environments, surface soil erosion, spread of exotic species,… etc.).

Particularly in view of the situation described above, the project has provided actions: - Preliminary analysis environment, fauna and flora; - Training courses, meetings of public awareness, production of informative material and construction of a dedicated Web site; - Recovery territorial Interventions (removal of exotic species, forest management, rehabilitation of degraded habitats); - Monitoring the quality of natural environments and the impact of works.

The main results achieved were as follows: 1. Adherence to the system of certification of forest management recognized at the level of European forests Regional Natural Reserve of the "Selva Lamone of" Action A6; 2. Safeguard measures in the woods, Action C1; 3. Construction of infrastructure read to prevent the passage on lawns (presence of rare species and orchids), Action C2; 4. Restoration of riparian buffer strip of River Olpeta and Lake Mezzano, Action C3; 5. Implementation of operations of wetlands along the riparian zone at the River Olpeta and Lake Mezzano, Action C4; 6. Periodic cutting grass in areas at risk of colonization by the invasive shrubs, Action D1; 7. Implementation of operations for forest management, Action D2; 8. Maintenance network paths of Regional Natural Reserve of the Selva Lamone and Lake Mezzano, Action D3; 9. Maintenance of riparian buffer strip at the River Olpeta and Lake Mezzano, Action D4; 10. Distribution of leaflets to the public with the involvement of schools and universities, Action E1; 11. Distribution of brochures to the public with the involvement of schools and universities, Action E2; 12. Allocation of sixteen boards and information boards in the most important points of SCI and Commons, Action E5; 13. Realization of press conferences, Action E6; 14. Accomplishing a public meeting with farmers' category, Action E9

Monitoring surveys and results

The project then has made concrete interventions naturalistic engineering and maintenance of natural forests designed to initiate a process of recovery now cannot be extended. The actions, even if localized, will bring a significant improvement in natural environments involved, with the consequent benefit to the species of animals and plants that they also host leading to increased intrinsic biodiversity habitats and encouraging the preservation of animal and plant species included in the Directive.
