definition
Forest Management
application of bus method & technical forestry principles
establishment, devt, maintenance & protection
forest resources
study &application of analytical techniques
selecting mgmt alternatives
organizational objectives
cutting cycle
interval between harvests

degradation vs deforestation
forest degradation
from old growth to 2nd growth forest
caused by logging & poaching

multi resource forest management
forest has equally important components
forest
single interactive system of plants, animals, soil, water, topography & climate
