Bowers, F.D. ND. Bryophyte surveys of selected old growth forest stands and other sites in northeastern Minnesota (1994-1996). Final report submitted to the Minnesota Department of Natural Resources. Unpaged.

Abstract:

Eleven sites were visited to survey bryophytes in northeastern Minnesota. These sites were composed mostly of old growth forests of White Pine (Pinus strobus), White Cedar (Thuja occidentalis), Yellow Birch (Betula alleghaniensis), and other areas of mixed woods, and were located in Cook County (4 sites), Lake County (6 sites) and St. Louis County (1 site). Ownership included 8 state areas and 4 Superior National Forest areas (one site had both state and federal ownership included). The taxa found included 55 hepatics (liverworts) and 185 mosses. One new taxon for the state was found, Tetraplodon angustatus (one of the "dung" mosses), and several others were identified for which there have been only a few previous collection sites in the state. The most species rich site was in the North Arm Area (Superior National Forest) north of Ely, where 105 taxa were found. The least number of species collected at a site was 55 taxa at Loon Lake near the Gunflint Trail (Superior National Forest). Opportunistic collecting was done at each site with a conscious thought to find as many "niche" areas as possible while covering as much of the stand as possible. Sites were visited in 1994 and 1995, and collections were worked up in 1994 through early 1996. Eleven days were spent in the field and over twenty two in the lab working with the specimens.
