GROUP: deciduous tree crops (od)
DEFINITION: deciduous tree crops 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 deciduous tree crop = uncommon TYPE not in classification (not peach, apple, pear…).
    2. mixed species deciduous tree crop = mix of different deciduous tree crop species, with no species >60% by cover if mature, or by stems if immature.
    3. non-productive deciduous tree crop = any species or mix of mostly deciduous 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. peach orchard = Prunus persica.
    5. apple orchard = Malus pumila.
    6. pear orchard = Pyrus spp..
  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)
