註釋

This guidebook is intended to assist field practitioners in determining forest health issues and the incidence of forest health factors in high-hazard forest ecosystems. The first section describes the attributes of hazard & risk rating and briefly outlines some available hazard & risk rating systems. Section two covers forest development plan-level surveys, and includes procedures for landscape-level forest health factor surveys. Topics covered include aerial overview surveys, classification of damage, map processing, survey for pest incidence, and windthrow risk evaluation. The final section reviews stand-level surveys. Appendices include a glossary, example inventory data & field data forms, and a table of damage agents & associated pest severity ratings.
