IN THE NEWS: Giant Sequoias Yield Longest Fire History from Tree Rings

Story by Mari N. Jensen, UA College of Science March 17, 2010

California's western Sierra Nevada had more frequent fires between 800 and 1300 than at any time in the past 3,000 years, according to a new study led by Thomas W. Swetnam, director of UA's Laboratory of Tree-Ring Research.

New Tree-Ring Lab building approved by ABOR


The Laboratory of Tree-Ring Research (LTRR) has been housed in the West Stadium for more than 70 years, with minimal improvements to their facilities. The Arizona Board of Regents has just approved construction of the Bryant Bannister Tree-Ring Building to house the UA's Laboratory of Tree-Ring Research. The $12 million project will be funded by a $9 million gift from Agnese N. Haury, the wife of one of the lab's founders, plus $3 million in nonstate funds. The building will provide about 26,700 square feet of office and laboratory space for the facility, which is currently housed primarily at Arizona Stadium. Construction is scheduled to begin toward the end of this year and be completed in mid-2012.

New Faculty Position: Forests in the Earth System

Announcing a new faculty position in Forests in the Earth System with the University of Arizona's Laboratory of Tree-Ring Research and the Institute of the Environment
The University of Arizona seeks to fill a faculty position in areas related to forests in the Earth System. We seek a quantitative scientist whose research addresses the interactions of climate, wildfire, forest growth and carbon dynamics, or a subset of these topics. The successful candidate will bring strong modeling and spatiotemporal analysis skills to complement existing strengths at UA in fire sciences, dendrochronology, paleoclimatology, the carbon cycle, remote sensing and tree and forest growth. We are especially interested in individuals whose research utilizes dendrochronology in novel and effective combination with other tools and methods to address basic or applied questions on these topics, particularly the scaling of understanding from landscape to global spatial scales.

2010 Summer Field Camp in Dendroarchaeology

The Laboratory of Tree-ring Research at the University of Arizona is pleased to offer its 10th annual presession course devoted entirely to the collection, analysis, and interpretation of archaeological tree-rings. Participants (undergrads, grads, professionals) will learn the most accurate and precise dating method used by archaeologists via lectures, laboratory exercises, and field work. The centerpiece of this intensive 3-week course is a field trip to various archaeological sites in western New Mexico area led by Drs. Ronald H. Towner and Jeffrey S. Dean. The first week in Tucson will provide participants with a basic background in dendroarchaeology. During the third week back in Tucson, participants will prepare, crossdate, and interpret the dendroarchaeological samples collected during the field trip.

For additional information, contact Ron Towner at
