Whether flying, crawling, swimming, or walking, many animals rely on the diverse array of habitat present at Hopewell Culture National Historical Park. Habitat types include eastern deciduous woods, fallow agricultural fields, riparian areas, native grasslands, and wetlands. National Park Service staff and volunteers are continuously monitoring native and invasive plants, birds, amphibians, mammals, insects, mussels, fungus, and reptiles. Restoration efforts are ongoing for native grasses and forbs in order to establish quality habitat for grassland nesting birds.
