Bogs, Swamps, and Marshes in Relation to 
Wisconsin Game Animals 
The game animals, such as the rabbit, the doer, the ruffed grouse, 
the sharp-tailed grouse, the prairie ohicken, the sand-hill crane, and 
the quail are affected in several ways by the plants and animals of 
bogs, swamps, and marshes. These three habitats provide nesting cover, 
roost cover, yarding grounds, food, and protection against enemies. 
The small animals provide food for predators and fur-bearing animals, 
and act as buffers between the predators and the game. In addition the 
small animals, especially the mamle, act as intermediate hosts 
for parasites and disease organisms that affect game animals. 
Pesting Cover 
Sharp-tailed Grouse.- 
In 1934 sharp-tailed grouse were found to be nesting in a 
large bog in Jackson county. This bog was several miles in diameter 
and was mostly open sphagnum with a few patches of tamarack. On 
about-1 square mile of bog eigt nests were found by a crew of fire- 
fighters. In most eases the nests were simply a depression in the 
sphagnum and when the surfac sphagnum around the eggs was burned 
they became visible. These were the only sharp-tailed grouse nests 
found in 1934, while in 1930, 1931, 1932, and 1933 nests were found 
in patches of grass on drained peat together with prairie chicken 
nests. In 1934, sharp-tailed grouse were at the lw of their cycle, 
whieh indicates that they rely on sphagnum bog for "sting cover 
when their numbers are reduced. It probably also indicates that 
originally their chief habitat in Wisconsin was the sphagnum bog. 
Later they spread into the cutover lane i northern Wisconsin
