Abstract

The estimator developed in Van Deusen (1987) is generalized to allow for unbiased estimation of log or tree volume using the critical height method. Comparisons are made with importance sampling (Gregoire et al. 1986) that suggest that the critical height method is more efficient and robust. The critical height method also requires fewer computations in the field. For. Sci. 36(4):930-938.
