WI 2. Cedarburg Bog. Acreage: About 2000. 



Location: Ozaukee County; West Bend and Port Washington 15' quadrangles; 3 

 miles SE of Newburg; reached via town roads. 



Description: Considered one of the outstanding bog areas of southeastern 

 Wisconsin, it includes six lakes of varying depths and a complex mosaic of 

 vegetation types. There are marl deposits several feet thick underlying the peat 

 in some places, and the pH values are higher here than for typical sphagnum 

 bogs in Wisconsin. Eight major cover types include emergent aquatics, string- 

 bog, bog birch-leather-leaf heath, dogwood-willow, shrub areas, dead tamarack, 

 conifer forest, conifer-hardwood forest, and hardwoods. There is an excellent 

 tamarack swamp with some white cedar and a few black spruce. Very rich in 

 rare bog plants, including orchids, ericads, sundews, honeysuckles, and sedges. 

 Sandhill Cranes nest in the bog.

Encroachments: A dam at the outlet of Mud Lake, built in 1959 and sub- 

 sequently removed, killed some trees in the bog. Deer enclosures have been 

 constructed on two of the islands and some management to increase deer har- 

 vest is planned.
