The Laboratory of Tree-Ring Research (LTRR) offers short intensive courses in dendrochronology during the Univesity of Arizona's Summer Pre-session, intended not only for local students, but also for graduate and undergraduate students at other institutions, postdoctoral researchers, and working professionals with suitable backgrounds (undergraduates need to be advanced in dendroarcheology and dendroecology in order to register). In 2012 Tom Swetnam and Don Falk will lead a two-week dendroecology course, split between the main University of Arizona campus in Tucson and the Valles Caldera Science & Education Center in Jemez Springs, New Mexico, which will also be the venue for the 2012 North American Dendroecology Field Week, potentially allowing people to attend both courses.
