Interviewer instructions

For concentrations of plants, calculate the area and record code 1. The rule is that a
concentrated planting area must be no less than 100 m2
with normal density, area that is less than
100 m2
is not calculated as concentrated planting area. For sparsely planted plants, record the
current number of trees at the interview time and record code 2 (including trees planted on the
area of less than 100m2
)
- Calculate the cultivated area for concentrations of planted trees, that is , planted trees
are gathered into a place, and can be measured to calculate the area as the rule above.
- Calculate by number of trees for sparsely planted trees such as, in garden, around the
house, on the bank of canal, along the road... that can not be gathered in one place for
calculating the area.
- Perennial industrial plants are calculated for the whole area including newly planted
trees or those remaining from the previous years as of the interview time.
