Critical point relascope sampling for unbiased volume estimation of downed coarse woody debris

Sammanfattning

Critical point relascope sampling is developed and shown to be design-unbiased for the estimation of log volume when used with point relascope sampling for downed coarse woody debris. The method is closely related to critical height sampling for standing trees when trees are first sampled with a wedge prism. Three alternative protocols for determining the critical sampling points on a log are presented and simulations are employed to suggest the most efficient protocol to use in practice.
