In collaboration between INTERACT - International Network for Terrestrial Research and Monitoring in the Arctic and SITES - Swedish Infrastructure for Ecosystem Science, an information system called Interact GIS has been developed and made available for usage at INTERACT and SITES field stations. Interact GIS is a network and web-based service provider for currently more than 85 terrestrial research stations located in the arctic and northern boreal and alpine areas and for the researchers visiting these stations. A subpart of the network, SITES GIS, is focused on SITES research stations, which represent a variety of Swedish climate zones and ecosystems. This data management plan has been created to layout the principles and strategy on how the Interact GIS project will manage data. When reading the document, keep in mind that it is the principal plan and not full documentation. The plan will be kept as a living document, and whenever the project reaches new achievements or a need for further work on data management is identified, new content will be added to appendices in this data management plan (see Appendix). It is important for us to keep and show coherence between the plan and choices, initiatives and achievements reached. https://eu-interact.org/ https://www.fieldsites.se/en-GB
