Seral Stages Objective: Retain full range of cover types and seral stages. ‰Indicator: Area of old, mature, and young forest in each subunit by cover class

ƒTarget: Targets for each seral stage to be set for both the gross and net landbase

Fragmentation Objective: Avoid landscape fragmentation ‰Indicator 1: Range of patch sizes (current harvest pattern)

‰Indicator 2: Interior old forest for each cover class
