Measurement of roundwood: methodologies and conversion ratios

The ability to measure roundwood quantity and quality, and predict product yields is of great importance to forest industries. However, roundwood metrics is a topic that is often difficult to understand due to counterintuitive trends, inconsistencies and variability in a number of factors
