Ninety-eight percent of the award-winning Oak Hammock Marsh Interpretive Centre’s green roof is planted with prairie wildflowers and native grasses.

The Oak Hammock Marsh Interpretive Centre’s green roof includes 4,800 m2 of established native prairie grasses and wildflowers and has been used as nesting habitat by waterfowl and other bird species. NPS continues to apply the experience learned and information gained from this initial green roof project. We are responsible for the roof’s ongoing care and maintenance, conducting prescribed burns on the roof every four to five years to manage and encourage the prairie species while controlling unwanted species.
