Shannon and Weaver Biodiversity Index (H’) of vascular plants at three rocky (R1 = Coscia di Donna, R2 = La Frana, R3 = Cala Barca) and three sandy (D1 = Li Junchi, D2 = Platamona, D3 = Porto Ferro) sites, censused at three Belts (Belt 1 = 0-50 m from the sea; Belt 2 = 51-100 m; Belt 3 = 101-150 m), by means of five point transects (every 100 points) per belt.
