The Permanent Grassland layer shows for agricultural parcels, if, based on the declaration in preceding years, an area is to be considered as permanent grassland or arable land. If the number of years of green cover is less than 5, the parcel is considered as arable land. If the number is 6 or more, the parcel is considered as permanent grassland. Attention: If the number of years of green cover is 5 and the parcel is used as grassland in the current year, the parcel becomes permanent grassland in that year.
