Tree density is calculated by formulating weight in grams per cubic centimeter of wood.
Analyzing tree density can serve great ecological and scientific function. The tools used to accumulate this knowledge are generally uncomplicated and minimize any ensuing damage done to tree specimens.
Equipment
Analysts use an array of equipment to test for wood density. The first is a wood auger to remove a sample. Water baths are used to bring the wood sample to a desired moisture level in the first phase of testing. Ventilated ovens are used to supply the drying effect that will remove moisture after water immersion.
Steps
John K. Francis with the U.S. Forestry Service espouses four steps in determining or testing tree density. The sample is taken from the tree, placed in water to observe the increase in liquid volume. After this, the wood is thoroughly dried and the two resulting figures--water displacement and end weight--compared
Significance
One of the benefits of using an auger is that it is minimally invasive with regard to the integrity of the tree. These methods make testing less harmful and calculations can be done with the smallest possible amount of tree material. That data can then be extrapolated to indicate the health and density of other trees within the same proximity.
