Dendroecology

microscope and tree core samples By studying annual growth rings of trees, scientists can infer much about the conditions in which a tree has grown. Dendroecology is the science of analyzing the pattern, size, and density of tree rings to better understand the relationships, factors, and effects of climate and environment influencing tree growth and forest history. Tree-ring records are valued data for reconstructing past climate and for determining the sensitivity of tree species to environmental change for predicting forest response to future climate. Ring dating has also been useful to detect disturbance events of logging, hurricanes, fires, droughts, floods, freezes, earthquakes, volcanic eruptions, etc. for relating natural and cultural history.
