Non-native Phragmites, also known as common reed, is a perennial, aggressive wetland grass that outcompetes native plants and displaces native animals. Because of its height and its distinctive, fluffy seedheads, Phragmites is easy to spot, even by traveling motorists.

- Dense growth along shoreland areas makes it difficult to access open water.
- Overtakes habitat and outcompetes native aquatic plants, potentially lowering diversity.
- Provides unsuitable shelter, food, and nesting habitat for native animals.
- Dense root systems change the hydrology of wetlands.

Japanese KNotweed
Japanese KNotweed
Japanese KNotweed
is a large species of herbaceous perennial plant of the knotweed and buckwheat family Polygonaceae.[1][2] It is commonly known as Asian knotweed[3] or Japanese knotweed. It is native to East Asia in Japan, China and Korea. In North America and Europe, the species has successfully established itself in numerous habitats, and is classified as a pest and invasive species in several countries.[2][4][5][6]
Japanese knotweed has hollow stems with distinct raised nodes that give it the appearance of bamboo, though it is not related. While stems may reach a maximum height of (10–13 ft) each growing season, it is typical to see much smaller plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves are broad oval with a truncated base, (3–5 1⁄2 in) long and (2–4 1⁄2 in) broad, with an entire margin. The flowers are small, cream or white, produced in erect racemes(2 1⁄2–6 in) long in late summer and early autumn.
