Combining taper and basic wood density equations for estimating stem biomass of the Populus x canadensis I - 488 variety

Stem biomass estimates are useful for various purposes. For example, the amount of commercially usable timber, carbon stock and energy fuel potential are directly related to biomass quantity. This paper describes the development of a biomass flexible equation for poplar (Populus x canadensis I - 488...
