THE VEGETATION AT POINT AU SAUBLE NATURE PRESERVE, BROWN COUNTY, WISCONSIN, USA

摘要

I conducted an ecological study of Point au Sauble Nature Preserve on the east shore of Green Bay, Brown County, Wisconsin. Typha latifolia and Phragmites australis were the most common herbaceous species found at the Point au Sauble Nature Preserve. Acer negundo was the most common tree species detected. Of the 46 species found, 15 were exotic/invasive species. The introduction of exotic/invasive species at the Preserve may be from migratory birds, continual wave action from Green Bay, and/or anthropogenic disturbance. The current low-water years in the Great Lakes Basin has allowed the invasive species P. australis to colonize the inner wetland of Point au Sauble. As a part of this research, I developed a permanent sampling grid to be used by future student and faculty researchers to monitor the vegetation at the Point au Sauble Nature Preserve.
