IDF Timber Supply
In a recent timber supply review for the Merritt Timber
Supply Area3, "dry" Douglas-fir stands account for about
101 000 ha in the timber harvesting land base. Most of this area
is designated for selection4 management systems.
However, determining where to draw
the line between merchantable and unmerchantable for individual
stands that make up the whole dry Douglas-fir forest is problematic.
Variation between the forest inventory labels and actual stand
conditions is high. Potential productivity can not readily be
determined from the height and age of dominant trees on the sites
because of past suppression. Otherwise productive sites may have
low current net volume yields because of heavy past removals and/or
root disease losses. A challenge lies in differentiating between
stands for which productivity can be profitably improved through
management (e.g., root disease control, site preparation, fill
planting and/or commercial thinning), and those which are truly
below the productive threshold.
The Pothole Creek Demonstration Area represents a concerted effort
by staff from consultants, licencees and the Ministry of Forests
to understand and address these issues.
