Bishop's Bog Preserve

A thoughtfully planned and well-maintained parks system contributes to the quality of life of its citizens and ensures a legacy for future generations to enjoy. To the City of Portage, protecting its natural treasures is an investment in the health, growth and stability of the community without being a burden on city resources. Parks reflect a community's attitudes, desires and dreams. They are our line in the sand to oppose man's encroachment on nature. But these beautiful, unspoiled places are also a rest for our souls so enjoy them, and leave only your troubles and footprints behind.

Bishop's Bog Preserve is another natural treasure of the City of Portage. This 152-acre preserve is the largest "relict" bog in Southern Michigan. Ancient and untouched, it is home to several rare plant species, including the Orange Fringed Orchid and Stemless Pink Ladyslipper. The bog is registered with the Nature Conservancy.
