Summary

High Habitat MDWR






cruising, layout, planning &
supervision

Harvester/Forwarder is the
right method

Less expensive to make
decisions in your boots, than in
the cab of a machine
Pulpwood market

$0.25/m3 stumpage
Presented costs do not include


Though marking is expensive,
it needs to be done
On this trial we broke even


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

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.
