Laboratory of Tree-Ring Research

The primary mission of the Laboratory of Tree-Ring Research is to remain in the forefront of world dendrochronology through the use of tree rings as natural chronometers and recorders of change in the environment with which human society is inescapably linked. The Laboratory makes significant contributions to understanding natural environmental variability in climatic, hydrologic, geomorphic, and ecological systems.

They are committed to promoting public awareness (and understanding) of science and making informal contributions to science education. As part of their Outreach program, they strive to inspire new connections and nurture existing connections among our community, which includes visitors to and residents of Tucson, and the K-12 educators and students communities.
