ABSTRACT
Management of forest-based biomass feedstock areas (forested land) requires knowledge of the location and current volume of timber resources. The role of measurements is to supply the numerical data required to make produce management decisions. Most of the calculations made in the forest-based biomass energy industry have units connected or associated with them. Whereas the number tells us how many, the units tell us what we have. When we measure something, we always have to specify what units we are measuring in. In its broadest sense, measurement consists of the assignment of numbers to measurable properties (Husch et al., 2003).
