About the Clark & Avis Spike Preserve

Located in the picturesque Sharon Short Hills, the preserve is characterized by rolling terrain and various ecosystems. A large wetland complex, containing an emergent marsh, a wet meadow, and a shrub area, is located in the eastern portion of the property. Three smaller wetlands occur in the western portion. As you head north along the first boardwalk, which starts just beyond a kiosk, you will reach open fields of grasses and forbs. The trails and boardwalks provide the opportunity to observe the gently rolling terrain and, further along, broad vistas of the surrounding wetlands and rural landscape. To the north, an established woodlot features a mixture of tree sizes of native species: basswood, black cherry, maples, and oaks. A perennial stream meandering through the property provides good aquatic habitat and serves as the source for a man-made pond.

Clark and Avis Spike Preserve is operated by the Washtenaw County Parks & Recreation Commission and was purchased through the Natural Areas Preservation Program. The Preserve is managed in partnership with the adjacent landowner, Grass Lake Sanctuary (GLS)—an organization devoted to providing nature focused retreat experiences. WCPARC and GLS work together on stewardship, trail maintenance, and general care of the preserve.
