Project summary
The river Toce in the Alps is the next largest tributary of Lake Maggiore after the river Ticino. It is a very important site for nesting birds and especially migrating birds including priority species, such as the corncrake (Crex crex). The Toce fulfils a vital role as an ecological corridor across the Alps during bird migration.
The project aimed to help the conservation, rehabilitation and extension of the river and riverbank habitats along a stretch of the river Toce downstream Domodossola.
The project achieved some relevant results such as the creation of an area with different water levels down to a maximum depth of 1 m, thus favouring amphibians and birds in the locality of Prata (Municipality of Vogogna); the reduction of the presence of invasive exotic trees and shrubs in termophilous shrub habitats; the maintenance of suitable habitat for nesting birds in the lowland hay meadows through specific management intervention consisting in mowing; the creation of new alluvial forests.
