Battle Point Research Natural Area

Deer River
The RNA is located on a peninsula jutting into Lake Winnibigoshish and Cut Foot Sioux Lake. Marsh, lowland brush, small lake, quaking aspen (Populus tremuloides), red pine (Pinus resinosa), northern red oak (Quercus rubra), and sugar-maple/American basswood (Acer saccharum/Tilia americana) ecosystems are present. The site is one of the few remaining old-growth northern hardwood forests occurring within the Chippewa National Forest. The mature sugar-maple/American basswood (Acer saccharum/Tilia americana) stand is the distinguishing feature of the RNA.
