Essay on Carbon Sequestration at St. Lawrence University
There are several ways in which it can be measured, they are: fixed area plots, point sampling with prisms, meteorological, and using satellite radar. Fixed area plots and point sampling prisms both use allometric equations method to estimate biomass from measured tree dimensions. With fixed area plots and point sampling prisms determine the tree dimensions such as diameter at breast height (DBH). Prism sampling is an efficient technique for larger stands. Fixed area plots require more time and tend to be more specific about what trees lie in the measured plot. See the document Tool for Estimation of Stocks in Carbon Pools and Emissions from Emission Sources under references to view the extensive formula and procedures to calculate the above ground carbon storage.
A simplified equation that can be used to estimate the carbon in a tree can be found in Forest Management and Planning. The equation given to give an estimate is: weight = (specific gravity of wood) x (density of water) x (volume of tree or stand of trees) (Bettinger 24). This equation would be
