Dendrochronological Applications


Dendrochronology:
  • ology: the study of
  • chronos: time, or more specifically events in past time
  • dendros: using trees, or more specifically the growth rings of trees
Applications in dendrochronology include:
  • ecology: insect outbreaks, forest stand structure, past fires (see image to the right):
    • The white arrows indicate distinct fires of the past
    • Each of those fires has been dendrochronologically dated to the year it burned
  • climatology: past droughts or cold periods
  • geology: past earthquakes, volcanic eruptions
  • anthropology: past construction, habitation, and abandonment of societies

Common objectives: To meet these objectives, the exact year of formation of each growth ring must be known: Good idea: Follow these web pages to learn why and how to crossdate with skeleton plotting and then try skeleton plotting for yourself.
