Based on a career of collecting by John W. Thomson throughout the arctic, the University of Wisconsin has one of the best collections of arctic lichens in the world and probably the most extensive for North America.  All of these collections are being digitized through two US National Science Foundation grants and are/will be available through the Consortium of North American Lichen Herbaria (CNALH – http://lichenportal.org). The Consortium web portal is based on the software Symbiota (http://symbiota.org), which provides the functionality for developing virtual floras like this project and for many contributors to collaborate on a project like this. The combination of a consortium approach and Symbiota’s functionality will make not only J. W. Thomson’s specimens available to the project but potentially all digitized specimens collected in the arctic. Euroasian lichen herbaria with significant arctic holdings are invited to collaborate. Anyone with appropriate access rights may upload images to illustrate species, contribute to species descriptions, which in turn may be used in contexts other than this Arctic Flora Project, and manage their own checklists. Current capabilities for generating dynamic checklists, keys, species descriptions and distribution maps are illustrated during this presentation.
