Abraham's Woods

Abraham's Woods is a 40-acre forest in Green County featuring sugar maple, basswood, red oak, bitternut hickory, hackberry, butternut, slippery elm, and white oak trees. These species grow across varying terrain shaped by a sandstone ridge that runs through the property.

The University of Wisconsin-Madison took ownership of the forest in 1961, earning designation as a Wisconsin State Natural Area and later a National Natural Landmark in 1973. This protection status secured the woodland for long-term research and conservation efforts.

The forest serves as an outdoor research laboratory where students and scientists study ecological systems and forest management techniques.

The forest is accessible through marked hiking trails that wind through the varied terrain. Visitors should wear sturdy footwear and be prepared for the changing elevation and ground conditions.

A natural bowl-shaped formation exists within the forest created by an east-facing sandstone ridge that produces distinct ecological conditions. This geological feature influences water drainage, sunlight exposure, and soil composition across different zones.
