Treasure Hunts
By guest contributor and collections volunteer, Nancy Lizette Berlin
Ah the humility. Last June while hiking to Morgan Falls I spotted a cinnamon fern just off one of the boardwalk bridges along the trail. The coppery cinnamon-colored sporangia stood boldly against the bright green foliage that abounds in spring. As part of filling gaps in the Cable Natural History Museum herbarium collection, I returned to the trail, permit in hand to collect a sample this September. Humbled, I was not able to relocate the plant that was so easy to spot a few months earlier. I will return next spring and try again.
Currently the museum houses 18 of the 47 ferns documented for Bayfield County by the Online Flora Atlas – Consortium of Wisconsin Herbaria. If you have interest in native plants, this is a great reference site that includes information on the more than 2,600 vascular plant species that occur in Wisconsin. It includes photos, distribution maps, specimen records, and more.
