The Ecological Needs and Economic Benefits of Bald Eagles Wintering in South Central Wisconsin (pdf)
The
Ferry Bluff Eagle Council (FBEC) began radio tracking wild Bald
Eagles in the winter of 2001. The tracking project was implemented
in order to enhance the existing understanding on the wintering
eagle population in Sauk Prairie and to provide insight about the
habitat requirements and limitations of eagles throughout the winter.
The radio tracking study is being conducted at a time when the Sauk
Prairie area is beginning to see an influx of development with the
expansion of State Highway 12 from a 2-lane to a 4-lane road by
the year 2005. This study benefits Sauk Prairie area planners and
the local community by acting as an information database on how
eagles use the area. The purpose of the project is twofold; 1) to
examine the ecological needs of bald eagles and how Sauk Prairie
meets those needs, and 2) to examine the economic factors involved
in maintaining the Sauk Prairie area as a vital bald eagle wintering
area. Understanding how eagles use this wintering ground as well
as how people value eagles in this area will ultimately lead to
the productive eagle habitat protection. |
