Nonnative plants and woody vegetation continue to degrade sections of the tallgrass prairie. Land uses surrounding the prairie and the proximity of ornamental plantings contribute to invasions of exotic species. Reed canary grass and shrubs have become abundant along the creek banks and in rills of the prairie.
In areas that are diverse and well-populated with native grasses and forbs, natural competition coupled with fire management appears to be sustaining native plants. Scientific studies of the park's plant communities plus management with prescribed fire and other methods can help to control invasive and exotic species. Seed collection and redistribution after a fire may increase native plant populations. Find research reports and data »
