This database contains over 29,900 records of documented occurrences of lichens in units of the U. S. National Park System. The records were obtained from the scientific literature, from National Park Service reports, and from the University of Minnesota Herbarium. Unpublished herbarium records from other herbaria are not included because they cannot be cited. Over 530 references reporting almost 2,650 lichen species from 153 park units (map) are included. Only parks with reported lichens are included in the database. We have been unable to locate lichen references for other parks in the National Park system. All lichen names were standardized to Version 13 (2008) of Esslinger's Checklist of North American Lichens. Please view the NPLichen Disclaimers before running any of the queries.

Currently you have a choice of three different queries (right). You may select a park and get a list of either lichens in that park or references associated with that park. You may select a species and get a list of parks that species occurs in, a map of parks where the species occurs (for added mapping functionality, please visit our lichen mapper), or a list of references associated with that species. And finally you may select a reference code to retrieve the full bibliographic citation for a lichen/park occurrence or to retrieve the list of species associated with that reference.

The result pages from these queries can be printed directly from the web browser using the print command, or can be copied and pasted into a word processor and printed. Use the back button on your web browser to return to this page after running each query.
