Some critics of dendrochronology suggest that the process of pattern-matching is highly error-prone.Are the long tree-ring chronologies inaccurate due to the inability of dendrochronologists to accurately match tree-ring patterns?None of these things are true of the oaks used in the European chronology.

One can use the amount of radiocarbon in the individual tree rings.The pattern of radiocarbon in the rings showed a maximum divergence, even at very old ages, of only around 40 years.This objective, quantitative test of dendrochronology showed it to be reliable and accurate.Also, oak trees and bristlecone pine or Douglas fir trees are very different.Bristlecones, for example, are evergreens which grow very slowly, at high altitude, in a cold, arid environment, and live for thousands of years.
