Site Description

Sensiba Wildlife Area is state owned and lies on poorly-drained sandy lakeplain. It is located on the western shore of lower Green Bay in northern Brown County, directly north of Long Tail Point. The wetland communities here have been drastically altered by a system of dikes and ditches.

There are two main wetland types at this site: a large emergent marsh dominated by cattails and interlaced with open water channels, weedy areas and clones of common reed; and a sizable but highly disturbed, open canopied, forested wetland lying between the emergent marsh and uplands to the west. This swamp is dominated by ash and other swamp hardwoods species, with a somewhat brushy understory of willow, dogwood and broad-leaved herbs.

This wetland remains an important breeding site for marsh birds and as a migratory stopover for both waterbirds and passerines. Both rare plants and animals have been documented at this site, but much of the habitat that previously supported these species has been destroyed or severely degraded.


Additional Comments

These wetlands are quite disturbed and the hydrology has been drastically altered by the construction of dikes and ditches.
