Allometry and partitioning of above- and belowground tree biomass in an age-sequence of white pine forests

The allometry and partitioning of above- and belowground tree biomass was studied in an age-sequence of four eastern white pine (Pinus strobus L.) forests (2-, 15-, 30-, and 65-year-old) in southern Ontario, Canada. Biomass in each tree component, i.e. foliage, branch (live and dead), bark, stem and root was quantified by destructive tree harvesting. Allometric biomass equations were developed for each tree component within each stand (age …
