Basic Tenets
Snow Interception Food Security and thermal
cover High, Medium and
Low Habitat
Continuous supply of Douglas-fir
Proximity to spring range
Slope, aspect, topography
6
Silvicultural Approach
Management Objective: Continuous supply of
large, wide crowned Douglas-fir
Strategy Clumpy Single Tree
Selection BDq regulation Regeneration gaps up
to 1 tree length in diameter
Retain clumpy structure

Summary
High Habitat MDWR By regulation the harvest
opportunity is limited Much of the growing stock is
poorer than sawlog High accounts for 1/3 of the
MDWR in the Cariboo IDF On this trial we broke even
$0.25/m3 stumpage Presented costs do not include
cruising, layout, planning & supervision
Harvester/Forwarder is the right method
Though marking is expensive, it needs to be done Less expensive to make decisions in
your boots, than in the cab of a machine
Pulpwood market Every pulp log we made cost us
money But those trees need to be cut to
release the growing space These treatments will improve G&Y
and contribute to long term habitat objectives

Peter commented that stand/harvesting conditions were as good as it gets so calculated costs would be on the low side.
