Dendroecology is the application of tree-ring analysis to ecological questions. Dendroecological studies have been an integral part of the LTRR's research program for decades. Our research focus is temporal aspects of forest dynamics. From fire history to insect outbreaks, we use tree-rings in concert with other ecological techniques to understand forests in the southwestern U.S. and around the world.
