Description:
The purpose of insect and disease damage surveys is to estimate
losses caused by various pests, so that the land manager
can prescribe appropriate management action.
Systematic ground data collection systems provide to the
land manager loss data that can be used for cost benefit
analysis, management plans, environmental impact statements,
and for projecting losses at a forest level. Damage survey
data could be integrated into timber management plans to
fill voids in stand models to predict losses. This handbook
describes field data collection procedures and data recording
necessary to operate the supporting computer program called
"INDIDS" (Insect and Disease Damage Survey).
