The beginning of earlywood formation and the end of the latewood formation form one annual ring, which usually extends around the entire circumference of the tree.A series of measured tree-ring properties, such as tree-ring width or maximum latewood density, that has been converted to dimensionless indices through the process of standardization.
Example: dating when trees were inundated by water to determine the sequence of lake level changes over time.
The science that uses tree rings to date and study past and present changes in wildfires.
This careful inspection helps us classify and record the narrow and extremely narrow rings, the very wide or average width tree rings, false rings, micro-rings, traumatic resin ducts, past injuries to the xylem from a vartiety of disturbance processes, changes in growth rates, even a location where a ring should be but is not.
Basically, this concept reinforces a central concept taught to all fledgling dendrochronologists: " As used in dendrochronology, this principle states that rates of plant processes are constrained by the primary environmental variable(s) that is most limiting. Tree growth “is controlled not by the total amount of resources available, but by the scarcest resource.” For example, precipitation is often the most limiting factor to plant growth in arid and semiarid areas.
NOTE TO READERS You may notice that the principles below represent a major change in the way we approach dendrochronology.
