GROUP: evergreen tree crops (oe)
DEFINITION: evergreen tree crops, mature & immature planted in a continuous regular planting pattern with spacing <5m apart and covering sufficient area to map a soft feature (width >5 m AND area >100 m2) OR with >60% vegetation cover. Must identify USE = Rainfed OR Irrigated, depending on the feature.

Classification

Return
  1. Object
    1. generic evergreen tree crop = uncommon TYPE not in classification (not mandarin orange, litchi, longyan…)
    2. mixed species evergreen tree crop = mix of different evergreen tree crop species, with no species >60% by cover if mature, or by stems if immature.
    3. non-productive evergreen tree crop = any species or mix of mostly evergreen tree crops that are >60% mature (by # of stems) but have been or will be non-productive for at least two years because of old age, disease, or cutting back to regenerate.
    4. mandarin orange orchard = Citrus reticulata.
    5. itchi orchard = Litchi chinensis.
    6. longyan orchard = Dimocarpus longan.
  2. Modifier 1 (maturity)
    1. immature = too young to produce.
    2. mature = productive
  3. Scale (of individual plots)
    1. small (<30m)
    2. medium-scale (>30m to 1ha)
    3. large-scale (>1 ha)
