Along the shores of the Galien River a narrow strip of bare ground was exposed in July and August. The ground of this strip is mostly mud, but in a few places it is sand or gravel. Usually the habitat is narrow, but in some places it is five to ten feet wide.
Tracks of raccoon were frequent on the shore along the river. From a few mouse traps set on the bare mud shore one northern white-footed mouse was taken August 4 beside a drift log.
Mud-bar herbage habitat:
Peromyscus leucopus noveboracensis. Northern white-footed mouse. 4.
A few small recently formed mud bars occur along the Galien River in its outer bends. These bars have not yet had time to become forested, and on their outer edges nearest the river there is usually no vegetation, this part being included in the shore habitat. On their older portions next the forest of the flood-plains occurs a thick growth of herbs, several annual grasses, and rarely a willow, Salix sp., or a seedling tree of white elm, Ulmus americana, cottonwood, Populus deltoides, maple, Acer rubrum or saccharinum, and others of the typical flood-plain species. The vegetation during August is very thick, and reaches a height of four to six feet. The soil is either mud or in a few places fine sand, and the ground is quite moist.
In this habitat four northern white-footed mice were trapped August 3–4.
Flood-plain forest habitat:
Scalopus aquaticus machrinus. Prairie mole. Ridges.
Blarina brevicauda talpoides. Short-tailed shrew. 4.
Procyon lotor lotor. Raccoon. 1.
