Current Crater Lake Botanists: Steve Jessup


<< Previous | Table of Contents | Next >>

While Buktenica is looking at moss beneath the lake’s surface, Steve Jessup of Southern Oregon University is surveying the mosses along the lakeshore. There, an environment shaded by steep caldera walls in proximity to the cold water of the lake creates a cool, moist habitat for species of mosses and liverworts that are normally found further north. Partially funded by the Crater Lake Natural History Association, Jessup’s two-year survey began in 2004. One of the first moss specimens he found was a species not previously recorded elsewhere in the Pacific Northwest, the closest known location being at higher elevations in the Rocky Mountains (S. Jessup, pers. comm.).
