I'm happy to announce that Kurt and I, along with Neil Pederson and Kevin Anchukaitis (Lamont-Doherty Earth Observatory) will convene a session on dendrochronology at next February's meeting of the Association of American Geographers in New York City.

Tree rings are a powerful and flexible tool that can be used to address a whole host of problems in the earth and environmental sciences. At the same time, whenever we try to use tree rings as surrogate measures of environmental change, we always find ourselves faced with the same questions. Is my dating correct? Which records should I include in my reconstruction model? Is the relationship between my tree-ring record and the environment robust, stable and reliable?

Because AAG is always such a great outlet for research in dendrochronology, we thought it would be appropriate to organize a short, targeted session that would allow some of the top tree-ring scientists in the world to take a step back and consider these larger issues. I'm really pleased that so many folks have agreed to join us in New York, and we are sure to have a very productive and enjoyable discussion.

Tree-ring analysis is one of the most powerful tools available to study environmental change and the interactions between climate, ecology and society. At the same time, scientists are faced with an emerging set of fundamental biological, ecological, and statistical issues that test our ability to robustly describe tree-climate relations or evaluate the ability of tree-ring records to serve as surrogates of climatic or ecological systems.
    In this session, we will present papers that explore some of the challenges involved with developing tree-ring records and interpreting those data as environmental proxies. We are particularly interested in contributions that test the assumptions underpinning key tree-ring 'principles', identify and evaluate the strengths and limitations of common analytical approaches, and apply novel methods to clarify the relationships between tree growth and the environment at a range of temporal and spatial scales. We will also feature papers that address the physical or biological mechanisms that link tree growth to environmental influences and the interpretation of low-frequency behavior in tree-ring data.
