Abstract

This report describes a standard procedure for destructively sampling the forest floor by depth class, oven-drying the material, and comparing the actual moisture contents against empirically derived regression equations of forest floor moisture versus DC for representative mature coastal and interior British Columbia forests, and for white spruce forests in southern Yukon. The field verification procedures and calibration equations presented here will be applicable to DC startup, not only in early spring, at any time during the fire season that a fire weather station started up; hence, this report is relevant to prescribed burning and project wildfire operations, as well as to fire danger rating network stations.
