The stems of trees can vary greatly in shape, and forestry professionals need to be able to accurately account for tree shape when they estimate how much wood is in a forest stand and what types of products the trees in those stands can be used for.
Researchers are developing mathematical models called taper equations for jack pine and black spruce using data collected in plantations (as opposed to natural forests). These equations allow researchers to account more accurately for tree shapes when estimating how much wood is in a plantation and what products could come from that wood.
This work is supporting MNR's Wood Supply Strategy and will help resource managers to better predict future wood supply in forest management plans.
