Tree ring dating database
Taking core samples at a point in the year where pests and rain are less likely to be present can help lessen some of this risk.
Once the core sample is obtained, the tree’s age is determined by counting the number of rings evident in the sample.
This does not apply to pieces of wood with fewer annual rings.
Sequences of annual rings is then compared with existing reference databases and an attempt is made to precisely classify them by year, Nicolussi explains.
This method of sampling is less harmful to the tree, but taking part of the tree core does run the risk of injuring the tree.
Pests, the natural elements, and other things can also invade the core of the tree after a core sample is taken and harm the trunk.
Trees that cannot be dated using the tree-ring method include some species of palm trees, as well as certain trees that grow in desert conditions.
Multiply the result by the growth factor for that tree species as given by the International Society of Arboriculture.Much can be learned about a species of tree and its environment by discovering its age, and researchers employ several methods to date trees.The most common, most accurate way to find the age of a tree is to count the number of rings visible when their trunk is cut horizontally.The tree-ring dating method works well for most trees; however, it cannot be used to find the age of all trees.That is because some trees don’t have rings or they have rings that are very hard to discern from a trunk cross section or sample.
