Forest vegetation and old-fields colonization by woody species in a region of the Julian Prealps, Taipana-Udine

Species composition of woody vegetation, density, health, regeneration, evolution trend in the short time and landscape dynamics in recent time (last 50 yr) were studied. Secondary succession models have been described by reconstructing the phases of colonization by forest vegetation in old fields. Fast colonization and success of woody vegetation, particularly Fraxinus excelsior, Alnus glutinosa and Acer pseudoplatanus characterize the process.
