Urban Green Space
The park's primary biome is urban green space, characterized by managed lawns, a variety of trees, garden beds, and landscaped areas. This environment is home to common urban wildlife such as squirrels, songbirds, and small mammals and supports a mix of native and non-native plant species adapted to an urban setting.
Riverine Ecosystem
Bordering the Mississippi River, the park also contains elements of a riverine ecosystem. This biome includes a mix of riparian vegetation, such as willows, cottonwoods, and various grasses and shrubs that stabilize riverbanks and provide habitat for birds, fish, and amphibians.
Prairie Remnants
Scattered within the manicured areas, visitors may find remnants of the native prairie biome, featuring grasses like big bluestem, switchgrass, and native wildflowers. These areas support pollinators such as bees and butterflies, as well as small mammals and birds.
Cultivated Gardens
In addition to natural biomes, the park includes cultivated gardens designed to enhance the beauty of the area while providing food and habitat for native wildlife. These gardens often feature ornamental plants and flowers, attracting various insects and birds.
Historical Landscapes
The park also maintains historical landscapes, which aim to recreate the vegetative settings present during significant historical periods. These landscapes incorporate historically accurate plantings and natural features to offer visitors a glimpse into the past ecological conditions of the region.
