The DendroEcological Network (DEN; is an open-source repository of high quality dendrochronological and associated ecological data. The DEN, a collaborative effort among partners from the Geography Department at the University of Vermont, the Forest Ecosystem Monitoring Cooperative, and the USDA Forest Service Northern Research Station, was launched in 2018 with the goal of providing a database and online infrastructure to archive these data, and make those data easy to find, explore, and aggregate across disparate research projects. This technical report serves as documentation of the infrastructure underlying the DEN for reference by those interested in its construction and capabilities, the data model used to develop the DEN, including the implementation of the Ecological Metadata Language standard and the Tree Ring Data Standard, and the technical details of implementing that model. The report closes by identifying potential next steps in the development of the resource.
