Specimen Databases

The RM specimen database contains over 700,000 specimen records from RM and USFS, most of which are publicly available through our online search pages below. Nearly all specimens have been assigned latitude & longitude coordinates for use in mapping applications. Scientific names are standardized to those contained in the RM checklists.

RM Specimen Database
Access 823,368 vascular plant specimen records from The Rocky Mountains and western North America. Search by label data or by defining an area on a map. View results as a list of specimens and an interactive map of specimen distributions. Data can be downloaded in several formats.


Type Specimens at RM

Over 5,000 type specimens are housed at RM. These will soon be accessible online with label data, annotation histories, and high resolution images of each specimen.


Grand Teton National Park Digital Collection
Developed by the University of Wyoming Libraries, the Grand Teton National Park digital collection can be accessed online with high resolution images for each specimen.  Over 8,000 specimens are available in the database.



Atlas of the Vascular Plants of Wyoming
View distribution maps for nearly all taxa known to occur in Wyoming. Maps may be viewed by selecting taxa from a checklist. These maps were generated in 1998 bases solely on data from the RM specimen database and include locality data for approximately 198,000 specimens from about 9,000 sites.
