Location of the Arboretum in Madison, WI
The University of Wisconsin-Madison Arboretum is an environmental research and outreach facility with a mission to "conserve and restore Arboretum lands, advance restoration ecology, and foster the land ethic." As part of its mission, the Arboretum maintains a 1,200 acre collection of restored ecological communities in Madison, Wisconsin. The arboretum is open to the public for educational and recreational activities.
Stomwater at the Arboretum
Restoring and maintaining natural ecosystems in an urban environment is a challenge. One of the largest threats to the ecosystems is stormwater from the nearby urban areas. According to the Arboretum's latest Stormwater Management Plan, an average of 470 million gallons of urban runoff - enough to fill over 700 olympic-sized swimming pools - runs through the facility each year before ultimately draining to Lakes Wingra and Waubesa.
Evaluating Innovative Stormwater Management Techniques
In accordance with the Arboretum's joint goals of research and ecosystem restoration, researchers are evaluating innovative approaches to ecologically-based stormwater management at a newly constructed, stormwater treatment wetland in the southeast corner of the Arboretum. Research at the site is detailed on this website.
This site was funded by Walmart. UW-Arboretum Pond 2 Wetland Basin was constructed with funds from the State of Wisconsin, City of Madison, and Town of Madison. Research at the wetland stormwater facility is funded by the Great Lakes Restoration Initiative (EPA) and the UW Graduate School.
