The Huxley Tree Ring Laboratory (HTRL) is a research unit within Western Washington University’s Huxley College of the Environment created in 2006 by Dr. Andy Bunn. Since then the lab has undertaken research from around the globe in the areas of remote sensing, dendrochronology and dendroecology. Members of the lab have created a broad collection of chronologies spanning the Pacific Northwest region and the Canadian and Siberian boreal forest. The lab strives towards an interdisciplinary research based educational environment with a focus on both graduate and undergraduate research. This website contains information about current research projects and the people enacting them, a photo archive, and information on the many products of the lab and its collaborators. This site was created to establish connections with potential collaborators and to share our excitement for the work we do here at the HTRL.
Home of dplR
The HTRL is the home of the the Dendrochronology Program Library in R (dplR), an open-source software package for analysing tree rings.
The Lab
The HTRL is outfitted with two Velmex tree ring measuring stations that utilize trinocular microscopes, analog and digital video displays, a data archive, and a downdraft sanding station, and field equipment. The lab also houses student researchers who are equipped with the required software and computing capabilities to perform remote sensing work at a variety of scales.
