The original area for the Kawishiwi was 2,635 acres of National Forest land. The research goals dealt primarily with finding the best ways to convert jack pine, aspen, and birch to white and black spruce. In 1955, the majority of the Kawishiwi reverted back to the Superior National Forest for management, leaving 116 acres for research activities. ClimateLake Superior influences the climate of nearby land, moderating extreme temperatures and increasing precipitation toward the northeast. Yearly rainfall ranges from 26 to 31 inches and average snowfall is approximately 60 inches. Temperatures range from -50°F in the winter to 98°F in the summer. Average seasonal temperatures are 42°F in the spring, 64°F in the summer, 45°F in the fall, and 12°F in the winter. Soil typesSeventy-five percent of the Superior National Forest in mapped as rock outcrop, 17 percent as till boulder clay, and 8 percent as moraine sand. Kawishiwi is mostly in the rock outcrop geological type. The land surface is generally rolling with alternating low rocky ridges and pat swamps. Some of the depressions are well drained and contain good quality loam soil of fair depth. The soil on the slopes and ridges is also of good quality, but is very shallow and rocky. These conditions make the area strictly non-agricultural. The podsolic profile is notably absent or poorly developed. Vegetation typesAt time of establishment, the forest was primarily jack pine (Pinus banksiana), black spruce (Picea mariana), white spruce (Picea glauca), and aspen (Populus tremuloides). Balsam fir (Abies balsamea), northern white cedar (Thuja occidentalis), maple (Acer spp.), white pine (Pinus strobus) and red pine (Pinus resinosa) were also present. Long-term data basesWe are not aware of any. Research – past and currentSilvics and silviculture of jack pine, spruce, and balsam fir especially on rock outcrop formations. No research is currently being conducted on the Forest. Major research accomplishmentsThe silvicultural research conducted in the first three decades of the Kawishiwi Experimental Forest added a great deal to the knowledge on the silvics and silviculture of jack pine, spruce, and balsam fir. This information furnished the basis for the handling of such species on the Superior, particularly on rock-outcrop formations. In the 1950’s, however, the timber types and condition classes of the Kawishiwi were no longer suitable for the research needs in northern conifer silviculture. CollaboratorsSuperior National Forest Research opportunitiesNo formal program currently exists. Proposals may be directed to the contact person. Facilities, contact address, locationKawishiwi Field Lab, Star Route 1, Box 7200, Ely MN 55731, is currently being used as a base for many wildlife biology studies with the University of Minnesota Field Station Wolf Project (team leader: David Mech, phone: 651-649-5231).
