| If the removal of wood and charcoal specimens is entrusted to a competent dendrochronologist, this destruction will be prevented. |
| Fire is the grassland's friend and the forest's foe. Thomas Swetnam is a dendrochronologist at the University of Arizona in other words, he studies the recent past through the medium of tree rings. |
| In some tree species growth rings can be difficult to discern and truly accurate ageing is best left to an expert dendrochronologist. |
| The principal aim of the dendrochronologist is to establish a tree-ring chronology where each year can be related to a relative tree-ring width. |
| If giving more than one possible match for a timber, the dendrochronologist should show why he does so. |
| The problem is general and any particular dendrochronologist may run into difficulty when he attempts to correlate an exotic ring pattern against an indigenous chronology. |
