GROUP: deciduous broadleaf trees (dw)
DEFINITION:
deciduous woody perennial
non-tree crops 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
|
- Object
-
generic deciduous woody crop = uncommon TYPE not in classification.
- mixed species deciduous woody crop = mix of different deciduous woody crop species, with no species >60% by cover if mature, or by stems if immature.
- non-productive deciduous woody crop = any species or mix of mostly deciduous woody 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.
- vineyard = Vitis sp.
- mulberry = Morus sp.
- Modifier 1
- immature = too young to produce.
-
mature = productive
-
Scale (of individual plots)
- small (<30m)
- medium-scale (>30m to 1ha)
- large-scale (>1 ha)

Dominance Rules

Return
|
- IF TYPE with greater vegetation cover area is very similar or otherwise unclear:
- Choose immature over mature over non-productive.
- Mix of deciduous tree crops and deciduous woody crops Choose deciduous tree crops> mixed species deciduous tree crop.
- Mix of evergreen woody crops and deciduous woody crops Choose evergreen woody crops > mixed species evergreen woody crop.
- Mix of evergreen tree crops and deciduous woody crops Choose evergreen tree crops > mixed species evergreen tree crop.
