In dendrochronology, the most serious limitation is that more variables affect tree growth and health than just moisture availability. Tree growth itself is very complex, as is interaction with the surrounding environment.
What is a drawback to tree rings?
Disadvantages of Tree Rings or Surrounds Soil on the trunk: One of the largest disadvantages of a tree ring is the amount of soil that comes into direct contact with the trunk of the tree. This can result in a buildup of moisture which can cause the tree bark to soften and decay.
Is Tree ring dating relative?
A scientific date is either absolute (specific to one point in time) or relative (younger or older than something else). Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results.
How do you determine the age of a tree-ring?
Start in the middle of the stump or cross-section of wood and count the first dark ring you see. Continue counting outwards from the middle ring until you reach the last dark ring. The total number of dark rings represents the age of the tree in years. Dont count the bark of the tree as a dark ring.
