Description
Nature restoration interventions are one of the types of active management and renaturalisation of provincial nature reserves.
They may consist of:
- A1 - removal of elements of environmental disturbance, such as landfills and roads
In some Reserves, at the time of establishment, considerable damage had already been inflicted due to the construction of infrastructure such as roads or landfills. Whenever possible, these sources of disturbance (also aesthetic) were removed, recovering the lost environments.
Examples: Lake Ampola, Roncegno, Taio di Nomi, Lake Pudro, Palù di Tuenno
- A2 - renaturalisation of lake shores
The lakeshores have been extensively modified for tourist-bathing use, through the removal of vegetation, consolidation with stones and gravel and the creation of paths. In these situations, the Reserves have intervened by reshaping the profile of the shoreline, removing discharged materials and encouraging the development of typical vegetation.
Examples: Lake Ampola, Lases, Prà dell'Albi-Cei
- A3 - renaturalisation of watercourses
Some stretches of watercourses in the Reserves suffered heavily from canalisation and "cementing" operations carried out in the past. In order to restore these environments to their ecological functions, including their role as habitats for flora and fauna and their function as water purifiers, the banks were remodelled and the watercourses were given new spaces by reconstructing a more natural environment.
Examples: Inghiaie, La Rupe, La Rocchetta
- A4 - restoration of the water table level in peat bogs subject to drainage
In peat bogs that had been subjected to drainage works in the past, the original water table level was restored by plugging the artificially created "holes" with peat fill. This prevented the rapid desiccation of the peat bog, which would have irreversibly upset its delicate balance.
Examples: Palù Longa and Palù Tremole
- A5 - reconstitution of hygrophilous woods
The hygrophilous woods of black alder, white alder and willows, typical of the wetlands on the banks of lakes and watercourses, are valuable but unfortunately increasingly rare environments. In biotopes, where suitable environmental conditions exist, attempts are made to reconstitute these important habitats through the planting of nursery stock and cuttings, which, given their particularly rapid development, are able to form new woodland formations in just a few years.
Examples: La Rupe, La Rocchetta, Roncegno, Borghetto
