Cultivated (CUL).
Crops are mainly the product of plant breeding, but also of native species such as walnut. Wild species collected from semi-natural vegetation are excluded.
Cultivated bare ground (SPA):
Elements with no crops planted or less than 30% cover of vegetation, including volunteers (self-seeded crop plants). Includes therefore only bare fallow or recently ploughed land which otherwise is recorded as a qualifier together with appropriate GHC.
Cultivated herbaceous crop (CRO):
This category includes both annual e.g. barley and sunflowers and perennials, e.g. lucerne and strawberries. Also includes crops that are technically bulbs e.g. daffodils.
Cultivated woody crops (WOC):
This category includes all elements with trees or shrubs, e.g. orchards, vineyards and olive groves. Cover cannot be used as a criterion because of pruning. Therefore the rule is that there should be at least 20 trees/shrubs per ha, otherwise the scattered tree code can be used.
