Some Principles of Dendrochronology

Illustrated with Graphics

The Principle of Limiting Factors

The rates of plant process occur as fast as allowed by the factor that is most limiting.

Tree-ring structures reflect the environmental conditions limiting growth during the time the ring was produced.

Tree Rings are Retrospective Indicators.

Variations in ring structure indicate past variations and changes of environmentally limiting conditions.

A Variety of Ring Features Reflect Environmental Conditions

Variations in these features can be quantified and used to interpret variations in these conditions.
