Environmental and climate information that can be precisely dated by the year can be gained from various tree ring parameters such as ring width, wood density, anatomical structures and chemical compositions. Dendrochronology thus offers a unique archive and precise tool for analysing human-environmental systems at the interface of archaeology, biology, climatology and ecology. The scientific potential and methodological limits of dendrochronology will be demonstrated, with examples from current research projects ranging from the cell to the hemisphere and from the present to the last ice age.
