Is this really all farmland ("An area of farmland used for tillage (cereals, vegetables, oil plants and other annual agricultural crops including flowers)")?
Most of it looks like meadow ("Used to tag an area of land primarily vegetated by grass plus other non-woody plants, mainly used for hay (meadow) or for grazing animals (pasture).")
I remember walking there some years ago and seeing mainly meadow for sheep, cattle and ponies on the island.
