State-of-the-art technique for measuring height of leaning, forked, crooked, or curved trees is briefly reviewed. The most efficient method employs an expensive tiltable range- finding dendrometer which can measure various types of leaning or nonlinear trees. However, a much less expensive tiltable nonranging hypsometer can be employed on straight leaning trees. This recently developed technique uses spherical triangulation observation points to eliminate bias attributable to lean in the slant plane toward or away from the observer. Necessary formulae and many numeric examples are given to aid in understanding the computational process. For. Sci. 37(6):1581-1590. 12
