     "text": "Florence Hawley Ellis was one of the first students of A.E. Douglass, the founder of dendrochronology, at the University of Arizona in the early 1900s. After finishing her Ph.D., she became a professor of Anthropology at the University of New Mexico, Albuquerque, where she had a long and distinguished career (1934 \u2013 1971). She contributed important work on the history of Chetro Ketl at Chaco Canyon, using newly developed dendroarchaeological techniques to determine the exact year structures were built over 1000 years ago. In addition, she was one of the pioneers of dendrochronology in the eastern U.S., where she tested whether new tree species were suitable for tree-ring dating and dendroarchaeological analyses of cultural sites of eastern Native American cultures."

     "text": "Working with a collaborative group of stakeholders, we are developing new fire history records from tree rings to inform forest and fire management decisions in critical watersheds in the southern Sangre de Cristo Mountains near Santa Fe, New Mexico.  The watersheds provide many ecosystem services (for example, water supply for the City of Santa Fe), and high-severity fires threaten the ecological and social values of the forests.  A long-standing science-management partnership in the region works to use science to guide local forest, fire, and watershed management."

We are expanding the network using a spatially systematic sampling approach with a main goal of reconstructing area burned since 1600 CE over a 300,000-acre area. These reconstructions will allow us to place recent \u201clarge\u201d fires (for example, 150,000 acre Las Conchas fire) in a historical context and ultimately can inform long-term carbon fluxes related to fire and climate."

In this project we will e) Define the geography of historical fire-climate relationships across North America, 2) Quantify the fire deficit in North America, 3) Develop a gridded continental fire history data set, and 4) Project future fire in North America."

     "text": "Seasonal increases in temperature and decreases in precipitation have increased drought stress among trees and forests of the southwestern United States. A more precise understanding of tree growth responses and vulnerabilities to climate change requires identifying climate and environmental drivers of tree growth at a seasonal or sub-seasonal scale. Xylogenesis \u2013 the study of wood formation \u2013 is a window into the timing of tree-ring formation on a cellular level. By collection microcores for trees on a weekly basis over the course of the growing season, the timings of tree-ring/cell formation can be estimated and linked to climate drivers. These analyses will identify potential triggers that may increase risks of future forest die-off. Project collaborators: Kiyomi Morino, University of Arizona; Kay Beeley, Bandelier National Monument."
