Abstract:A sampling method is developed for determining the total volume of a standing tree. The total volume can be converted to total dry weight (biomass) by applying well-known specific gravity relationships and then biomass can be converted to carbon. The suggested method uses importance sampling (IS) and is motivated by the pipe model theory of tree form. The critical assumption is that decurrent form tree crowns can be virtually collapsed into an excurrent form. Subsequently, standard IS ideas can be applied. The proposed tree volume estimator requires measurement of diameters at one or more upper stem heights. The method can be applied to either standing or felled trees.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
