  13. Subfields of Dendrochronology • Dendroarchaeology: Dating of Archaeological dwellings. • Dendroclimatology: Developing a record of past climate. • Dendrogeomorphology: Dating land movements such as landslides in the past. • Dendrohydrology: Creating a record of past water availability and flooding. • Dendroglaciology: Dating past movements of glaciers. • Dendrovolcanology: Dating the past eruptions of volcanoes. • Dendrochemistry: Using tree rings as a monitor of the chemical makeup of the soil. • Dendroecology: Recording ecological processes such as tree-line movement, insect outbreaks, or movement of invasive tree species. • Dendropyrochronology: Dating the past occurrence of forest fires. • Dendroentomology: The use of tree rings to reconstruct past population levels of insects. • Dendromastecology: The use of tree rings to reconstruct fruiting events in trees.
