Japanese barberry is a dense, deciduous, spiny shrub that grows 2 to 8 ft. high. The branches are brown, deeply grooved, somewhat zig-zag in form and bear a single very sharp spine at each node. The leaves are small (½ to 1 ½ inches long), oval to spatula-shaped, green, bluish-green, or dark reddish purple.

The fruits are bright red berries about 1/3 in (one cm) long that are borne on narrow stalks. They mature during late summer and fall and persist through the winter.

Phragmites australis is a non-native, invasive, wetland, perennial reed grass. Phragmites spreads aggressively by rhizomes and seeds and quickly outcompetes and displaces native salt marsh vegetation while providing little or no food or shelter for most saltmarsh-dependent wildlife. Additionally, Phragmites can eliminate small intertidal channels and decimate pool habitats that should offer natural refuge food for invertebrates, fish and waterbirds. Non-native Phragmites is distinctive due to the extensive dense colonies it forms and plume-like seedheads that generally persist through the winter on canes that range in height from 6 feet-15 feet tall and remain standing throughout the year.

English Ivy is a non-native invasive evergreen vine that covers and kills trees. Vines climbing up tree trunks envelope branches, blocking sunlight from reaching the host tree’s foliage, impeding photosynthesis. For additional information look at

The leaves are simple, dark green and shiny on top. It prefers moist soils and tolerates sun, but thrives in shade. It is commonly found in disturbed places like roadsides and fields. Glossy buckthorn has insignificant yellow-green flowers at leaf axils in spring. followed by dark purple berries in summer and fall. The bark is dark gray or brown with white lenticels.
Japanese Angelica Tree is a member of the Carrot family is capable of growing forty feet high. This species blooms white flowers wider than they are tall in late August. Stems are covered in sharp spines and small purple fruits generally appear in September. Manual hand pulling and digging of young plants. A weed wrench much be used for larger plants.

Japanese knotweed is a lump forming, semi-woody perennial three to 10 feet high. It produces sprays of small greenish-white flowers in late summer. The hollow stems are smooth with purple specks and have distinct nodes at leaf attachments. It is shade tolerant, thrives in a variety of soil and moisture conditions, and is commonly found along streams, rivers, or disturbed areas. Japanese knotweed can best be identified by hollow, bamboo-like stems with purple flecks and prominent nodes at leaf attachments. In late summer, sprays of green-white flowers are evident. Leaves are simple, alternate and generally oval with a flat base and pointed tip. New leaves may start out red and turn green in maturity.

Jetbead is a multi-stemmed deciduous shrub that invades understories despite shade. Most noticeable for its flowers. Grown as a desired ornamental in China and Japan, it quickly outcompetes native shrubs and can grow five to seven feet tall disturbing canopy layers.

Leaves are deeply veined, elongated and toothed - they grow directly opposite of each other.
Lesser celandine is a member of the buttercup family, lesser celandine is a spring ephemeral with glossy yellow flowers and dark green, heart-shaped leaves. It forms dense mats in riparian corridors, forested floodplains, wet meadows, and lawns, preventing the growth of other plants. By summer, lesser celandine dies back and disappears completely. The plant propagates primarily by small potato-like tubers that can be disbursed by water and digging animals. Once separated from the parent plant, each tuber has the potential to grow into a new plant.
