Upper Kaubashine Creek supports an extensive wetland community that is relatively undisturbed and contains a regionally significant concentration of springs. The creek is an important cold-water tributary to the upper Tomahawk River that supports a variety of wetland communities along its riparian corridor. Dense spruce and tamarack swamps along the margins give way to shrubby fens surrounding several large springs, which drain into Kaubashine Creek. The unique water chemistry supports rare plants. There is a steep upland ridge along the southern end of the property, overlooking the stream corridor. Forest type on the upland areas consists of jack pine, red pine, and a mix of northern hardwoods or aspen. In this portion of Oneida County, the only remaining significant tracts of undeveloped natural pine forest are on state-owned lands along the major river corridors. The site also supports a number of uncommon boreal birds. Upper Kaubashine Creek is owned by the DNR and was designated a State Natural Area in 2011.
