abstract

Close-to-nature silviculture for conservation and restoration of diurnal raptors forest habitats in the SCI Alpe della Luna-Bocca Trabaria. This study aimed to define suitable silvicultural actions for forest habitats conservation and improvement of four raptor species present in SCI “Alpe della Luna- Bocca Trabaria” (province of Pesaro and Urbino): Goshawk (Accipiter gentilis), Sparrow hawk (Accipiter nisus), Buzzard (Buteo buteo); Honey buzzard (Pernis apivorus). By means of a GIS multi-layered analysis we have crossed the information concerning the composition and structure features of the forest vegetation and the ecological requirements of the four raptor species. We have obtained a Forest Habitat Suitability Index (IIHF) that allowed to estimate the fitness of the different forest types and the priority of specific silvicultural treatments to improve the single bird habitats. Very important value have high forest (in transition from coppice) with Fagus sylvatica and Quercus cerris and those mixed with Abies alba, which are ideal habitats for diurnal raptors and in particular for Goshawk and Sparrow hawk. The proposed forestry actions are based on close-to-nature silviculture and aimed to obtain a structural and functional diversity of the forest stands in order to guarantee the conservation of the existing and potential ecological values.
