Considered the birthplace of ecological restoration, the UW–Madison Arboretum is a teaching and research facility that conserves and restores land, advances science, offers public outreach, and benefits from community involvement. The 1,200-acre grounds are home to protected prairies, woodlands, wetlands, savannas, springs, shoreline, a notable horticultural collection, and Wisconsin native plant gardens. It also offers 20 miles of walking trails and 4 miles of biking road as well as hundreds of learning and volunteer opportunities.
