Association for Tree-Ring Research The Association of Tree-Ring Research is aimed at research groups and individual scientists working in Europe, but also, of course, for everyone interested in tree-ring research.  They sponsor the annual TRACE meeting (Tree Rings in Archaeology, Climatology, and Ecology), educational opportunities such as fieldweeks and workshops, provide information and advice to colleagues and the public, and more.

Dendrochronologia  Dendrochronologia is an international scholarly journal in tree-ring research.  It publishes high-quality original research dealing with growth rings of woody plants and the application of tree-ring studies to problems in a wide variety of fields including, but not limited to, archaeology, botany, climatology, ecology, forestry, geology and hydrology.

Digital Collaboratory for Cultural Dendrochronology (DCCD)  The DCCD is a digital repository and interactive library of tree-ring data. Its content is developed through research of, among others: archaeological sites (including old landscapes), ship wrecks, buildings, furniture, paintings, sculptures and musical instruments. The DCCD is based on the Tree-Ring Data Standard (TRiDaS) and allows for conversion of other widely-used data formats. It contains digital tree-ring measurement series and average chronologies, as well as their descriptive and interpretative metadata.

International Multiproxy Paleofire Database (IMPD)  A database of both tree-ring and sediment charcoal based fire history data maintained at NOAA's National Center for Environmental Information.

International Tree-Ring Databank  The ITRDB is a repository for tree-ring data and climate reconstructions from around the world maintained at NOAA's National Center for Environmental Information.  

ITRDB Forum (Listserv)   In existence for 30 years, an international dendrochronology discussion forum that covers all aspects of tree-ring research, the ITRDB Forum has over 1000 subscribers.  You can subscribe or view the archives here.  (Originally the itrdbfor@listserv.arizona.edu)

Laboratory of Tree-Ring Research, University of Arizona The Laboratory of Tree-Ring Research was established in 1937 by A.E. Douglass, founder of the modern science of dendrochronology. The LTRR is a research unit in the College of Science at the University of Arizona in Tucson.  Since its founding, faculty, students, and visiting scholars have performed notable work in areas of climatology, archaeology, hydrology, ecology, and the history of fire and other disturbances.  It houses over two million wood research specimens and associated documents.

North American Dendroecological Fieldweek  The NADEF is a field-oriented workshop in applied dendrochronology held every summer at different locations around North America.  Participants range from new initiates in the field to seasoned veterans with over 20 years or longer of experience

Science of Tree Rings Web Pages This award-winning web page was built and is maintained by Henri Grissino-Mayer.  It is the most complete compilation of tree-ring information on the web.  It contains basic principles, references, jobs, laboratories, home pages of individual researchers, suppliers of field and laboratory equipment, software, and many other facets of the science.  

Swiss Federal Institute for Forest, Snow and Landscape Research  An active center of dendrochronological research, it maintains numerous data sets and images, including the Bibliography of Dendrochronology listing over 11,000 references in tree-ring research and the Multilingual Glossary of Dendrochronology that provides definitions and translations for 351 terms in 6 languages: English, German, French, Spanish, Italian, and Portuguese (and Russian in the printed version).

The Tree-Ring Times  is a Facebook forum dedicated to disseminating and discussing information, news items, and recent activities and advances in the tree-ring sciences.
