Laboratory of Tree-Ring Research
The University of Arizona
History and activities
The Laboratory
of Tree-Ring Research was organized in 1937 as an outgrowth of the pioneering
tree-ring studies initiated by Andrew Ellicott Douglass at the University
of Arizona in 1906. A division of the College of Arts and Sciences, the
Laboratory conducts a unique program of teaching and research in all aspects
of dendrochronology. Graduate-level instruction
is offered through cooperating academic departments, and a limited number
of graduate research assistantships are available to qualified students.
Current research efforts are directed toward the quantification of tree-ring
parameters, the establishment of new tree-ring chronologies throughout
the world, the use of tree-rings in the study of forest ecosystems, the
reconstruction of paleohydrologic and paleoclimatic variables, and the
documentation and development of prehistoric chronological controls. Along
with the world's largest collection of tree-ring specimens from living
trees and ancient timbers, the Laboratory maintains a variety of specialized
equipment and data files containing processed tree-ring chronologies, relevant
climatic and hydrologic records, and archaeological tree-ring dates and
site information. Sponsored research is currently funded by several agencies,
including the National Science Foundation, the U.S. Department of Energy,
the Environmental Protection Agency, the USDA Forest Service and the USDI
National Parks Service.
