| Impact Description | In studies where cattail litter was added to test sites, native wetland plants such as marsh bellflower (Campanula aparinoides), bulb-bearing water-hemlock (Cicuta bulbifera), and stiff marsh bedstraw (Galium tinctorium) did not emerge. Narrow-leaved cattail (Typha angustifolia) has large energy reserves in its rhizomes that supply new shoots with the necessary energy to push through the litter in the spring. |
