A modified timber cruise for the inventory of dead wood in Coastal forests: a field trial.
This report details the results of a study exploring the feasibility of collecting data on dead wood using a modified version of a coastal industry timber cruise.
An Operational trial to evaluate the effectiveness of using modified bucking/yarding practices in Coastal
Old-Growth stands to maximize CWD levels in the setting: Establishment Report.
In 1999, a multi-year operational study was initiated to evaluate the logistics, feasibility, and success of transferring procedures used in helicopter harvesting to other harvesting systems. The purpose of the study is to compare, for both conventional and modified harvesting practices, the operational costs as well as the post-harvest distribution and attributes of CWD over a range of sites.
Efficiency of six line intersect sampling designs
for estimating volume and density of coarse woody debris.
Six line intersect sampling (LIS)designs were used to estimate the volume and number of pieces of coarse woody debris (CWD)
per unit area in two forests in the Coastal Western Hemlock biogeoclimatic zone of British Columbia.
Measuring the length of Coarse Woody Debris.
Piece length is an important descriptor of CWD structure.
However, whether length needs to be measured depends on
the study objectives. If length is required, then strict adherence
to a set of rules is needed to ensure measurement consistency.
The considerations described in this paper are indicative of those
that need to be addressed in defining CWD piece length, and in
establishing and applying measurement rules for a sampling
