Description
Ordinary active protection and improvement measures are one of the types of active management and renaturalisation of provincial nature reserves.
They may consist of:
- C1 - mowing of herbaceous and reed vegetation.
In the past, the regular mowing of marsh vegetation for zootechnical purposes resulted, in many cases, in a valuable vegetation balance in Nature Reserves. With the abandonment of these agricultural practices, the overgrowth of more invasive vegetation - in particular water reed or pioneer woody species such as willow or pine - risks permanently changing the floristic composition of these environments, 'suffocating' the more delicate botanical species. To avoid this process, various portions of the Reserves are regularly mown.
Examples: Fiavè, Inghiaie, Roncegno, Laghestel, Sternigo, Lomasona, Le Grave
- C2 - creation of 'non-returnable crops
In some Nature Reserves some plots of land occupied by grassland or cultivation have been transformed into 'non-returnable crops', with the aim of providing valuable food for the birds that stop over during migration. In these crops, made from maize, sorghum, millet, panicle, rape, buckwheat, flax, sunflower and various other species, the fruit is not harvested, but remains available to the fauna.
Examples: Fiavè, Foci dell'Avisio, La Rocchetta, Roncegno, Fontanazzo
- C3 - construction of barriers and road 'subways' to protect the spring migration of amphibians.
In spring, frogs, toads and other Amphibians leave the woods to go to wetlands to mate and lay their eggs. Migrating at night, they are often mowed down on the roads by passing cars, with very negative repercussions on their populations. To avoid these authentic 'massacres', in some biotopes lined with roads, barrier systems with subways have been set up so that the amphibians can cross without danger.
Examples: Fiavè, Lake Ampola
- C4 - placement of artificial nests (floating platforms) for water birds.
Artificial nests, consisting of floating platforms, have been placed in some Nature Reserves comprising the shores of lakes and watercourses to encourage the nesting of certain species of water birds (especially Rallidae and Anatidae)
Examples: La Rocchetta, Levico
- C5 - fish passages
