Additional repositories for study skins were Tulane University and the University of Tennessee. Skeletal material not accompanied by study skins was deposited in the University of Tennessee Zooarchaeology collec- tion. Trapping localities are indicated on Figure 1, and several areas frequently sampled during the study are described in some detail. An annotated list of species collected is presented, with 1981-1987 data summarized in Table 1. Areas Frequently Sampled Trapping effort was concentrated in several areas, grouped together by habitat, and described below. Trapping area localities are indicated in Figure 1, and captures by habitat are tabulated in Table 2. Areas 1 and 2, Minnesota Mainland Wet Meadows: These grass and sedge areas typically have standing water except in late summer. Lack of trees is apparently caused by flooding due to beaver dams, with standing and fallen trunks of dead trees still conspicuous. Some woody plants (Red Raspberry, Tag Alder, Black Spruce, Balsam Fir) are beginning to reinvade, especially along edges. Areas 3-8, Minnesota Mainland Wet Wood- lands: All of these are on the mainland penninsula east of Smith and Schlei Island, and are typified by poorly drained woodlands with occasional standing water, a wide variety of trees with Black Spruce and Balsam Fir most common, a complete canopy with no grasses, and a virtual absence of exposed boulders. Mosses, ferns, Horsetail {Equisetum), and Ground Pine (Lycopodium) are prevalent, but the substrate lacks the spongy feel of a sphagnum bog. Area 9, Wadurski Marsh: This sedge and grass area on Red Pine Island is drained by a meandering stream and is contiguous with a shallow bay of Lake Saganaga. Scattered patches of woody plants (Sweetgale, Tag Alder) occur, but t
