Kleinstuck Preserve is a 48-acre nature preserve owned and managed by Western Michigan University. It is one of the few open spaces remaining in Kalamazoo, Michigan. This unique ecosystem includes upland forest, swamp forest, shrub carr and marshland, which are home to a wide variety of plants and animals. Some of Kleinstuck's special features include a beautiful showcase of native wildflowers in the springtime and a highly diverse bird population. The property is open to the public for passive recreation and is used by WMU and other educational institutions for research and education. Dogs are permitted on the property, but must be kept on a leash at all times to protect vegetation and wildlife as well as other people visiting the preserve.
Western Michigan University's Natural Areas Program partners with students and faculty, local ecological organizations, area schools and volunteer groups in order to promote environmental stewardship, provide research and education opportunities, and create healthier natural areas on WMU properties.
