The Biota of the Gordon Natural Area - Lichens

Lichen research at the Gordon can be described as being in its infancy. To date, no faculty members or students have undertaken any lichen research. Hence, the only GNA lichen data come from observations from GNA staff. As with the bryophytes and fungi, there are numerous photos of unidentified lichens awaiting determination.

To date, 49 species of lichens, in 35 genera, 20 families, and 10 orders have been noted at the GNA. This number of species only represents a very small portion of the lichens present at the GNA. As we continue working with this group, we hope to amplify the current species list significantly.

You can explore the lichen checklist below, or you can access a pdf copy of the checklist.
