University of Colorado Herbarium Databases


Welcome to the CU Museum Herbarium's Specimen Database.

We are currently updating our database to the new version of Symbiota

All specimen data are available, but several ancillary functions and look and feel are under construction.

We opted for a temporary solution over taking the site offline during the upgrades.

What are we working on? What has been digitized at COLO?

Label images for all North American Lichens and Bryophytes are in our database and are ~90% transcribed.

Non-North American Lichen packet labels are all imaged and ~50% have been transcribed.

Colorado Vascular Plants are all imaged and label data is in our database. ~85% are georeferenced.

North American Vascular plants are all imaged. Specimens from the Southern Rockies are mostly transcribed and georeferenced. Specimens outside of the region are mostly with skeletal database entries.

A list of completed families is available at this LINK.

We are currently digitizing non-North American bryophytes and expect to finish in the fall of 2024.

We are seeking funding opportunities to digitize our non-North American vascular plants, and our worldwide Algae, Non-Lichenized Fungi and Myxomycetes collections.

Our Algae (~8,000 specimens), Non-Lichenized Fungi (~12,000 specimens) and Myxomycetes (~900 specimens) have not been digitized in any form.

All-Asia TCN

Bringing Asia to digital life: mobilizing underrepresented Asian herbarium collections in the US to propel biodiversity discovery

This TCN will digitize ~40,000 vascular plant specimens from the Asian Continent. This is roughly 40-50% of our non-North American vascular plant specimens. (September 2021-August 2025)


Building a global consortium of bryophytes and lichens: keystones of cryptobiotic communities

This TCN focuses on the Lichen and Bryophyte specimens in our collection from outside of North America. We will image and database ~50,000 lichens and

~50,000 bryophytes contributing data to the lichen and bryophyte portals. (September 2020-August 2024)


Using Herbarium Data to Document Plant Niches in the High Peaks and High Plains of the Southern Rockies - Past, Present, and Future (SoRo)

COLO is the lead institution on the Southern Rocky Mountain TCN. Most of our efforts are going into the development of the Consortium of Southern Rocky

Mountain Herbaria Portal ( ), digitization is mostly complete (September 2017-August 2023).


Building Digital Collections and Infrastructure for the 21st Century at the University of Colorado Herbarium

Building on previous digitization efforts the Botany Section of the University of Colorado Museum (COLO) will image, georeference and transcribe all of its vascular plants form Colorado.

COLO has now imaged all vascular plants from Colorado. Images are actively being associated with the database.

Georeferencing is ~70% complete for Colorado portion of the vascular plant collection.

All lichens and bryophytes from Colorado have been transcribed.

All records housed at are now available here.
