• Deer herbivory is widespread (Judziewicz and Kopitzke 1999). A high diversity of forest birds<br />
including many warbler species was noted in 1988 (Zimmerman 1989).<br />
• There is one rare plant species present on the island (Judziewicz and Kopitzke 1999.) Rare roadside<br />
flowers were reported in the late 1980’s (Zimmerman 1989).<br />

Hat Island<br />
Hat Island is named for its shape. It is less than 2.5 acres in size, sitting low in Green Bay 2 miles<br />
from the <strong>Door</strong> Peninsula between Egg Harbor and Fish Creek. The island was once forested, however<br />
only a few dead skeletal remains of cot<strong>to</strong>nwoods still stand and a small colony of dutchman’s breeches at<br />
the highest point (Judziewicz and Kopitzke 1999).<br />
• Hat Island is in the Town of Egg Harbor. Egg Harbor utilizes an independent planning commission<br />
with a sub-division ordinance. The Egg Harbor Town Board enacted a mora<strong>to</strong>rium on commercial<br />
development from January 1998 <strong>to</strong> March 1999. Under the ‘master development plan’ wetlands,<br />
forests, the Niagara Escarpment and open space will be protected. The Nature Conservancy is<br />
working with the <strong>to</strong>wn <strong>to</strong> identify high quality natural resources in Egg Harbor (Grimm 2001).<br />
• Hat Island is privately owned. Land use is predominantly natural area.<br />
• Soils are nearly level <strong>to</strong> sloping on old glacial lake beach ridges. Dolos<strong>to</strong>ne bedrock is at a depth of<br />
40 or more inches (USDA SCS 1978).<br />
• Vegetation is comprised of dead cot<strong>to</strong>nwood (Populus del<strong>to</strong>ides), Dutchman’s breeches, red<br />
raspberry, wild black currant (Ribes americanum), chokecherry, and red-berried elder. Invasive<br />
exotic plants include motherwort and catnip (Judziewicz and Kopitzke 1999).<br />
• Hat Island is a breeding ground for herring gulls and cormorants (Judziewicz and Kopitzke 1999).<br />
• There are no known rare plant or animal species on Hat Island (Judziewicz and Kopitzke 1999).<br />
Adventure (Strawberry, or Big Strawberry) Island<br />
Adventure Island is approximately 20 acres and is located approximately 2 miles northwest of<br />
Fish Creek. The island was popular in the 1920’s and 1930’s as a boys summer camp. A Milwaukee<br />
Public Museum expedition made several plant collections in July of 1897 (Judziewicz and Kopitzke<br />
1999).<br />
• Strawberry Island is in the Town of Gibraltar. Gibraltar has adopted the county’s zoning ordinance.<br />
• The island is privately owned and maintained as natural area. Because of intense past human activity,<br />
native vegetation has been severely altered (Judziewicz and Kopitzke 1999).<br />
• Soils are nearly level <strong>to</strong> sloping on old glacial lake beach ridges. Dolos<strong>to</strong>ne bedrock is at a depth of<br />
40 or more inches (USDA SCS 1978).<br />
