Ecology and Phenology of Flowering Rush in the Detroit Lakes Chain, Minnesota
Flowering rush, Butomus umbellatus, has been an increasing problem in the Detroit Lakes chain of lakes for more than 45 years. Flowering rush dominates ecosystems by crowding out native species including hardstem bulrush, Schoenoplectus acutus; a vital part of native ecosystems. Furthermore, floweri...
