Goatsrue

Galega officinalis

Goatsrue is an herbaceous, shrub-like, multi-stemmed and deep-rooted perennial legume that grows between 2 and 6 feet in height. Mature leaves are alternate and pinnately compound with six to ten pairs of leaflets.

Glossy Buckthorn

Frangula alnus

Glossy buckthorn is a deciduous shrub, or small tree, that can grow up to 30 ft in height. Bark is dark gray to brown with white lenticels.

Giant Reed

Arundo donax

Giant reed is a perennial grass capable of growing up to 20 feet tall. Its leaves are up to 2 feet long and opposite in arrangement. It flowers in late summer with a purple to silver feathery plume atop its stem.

Giant Hogweed

Heracleum mantegazzianum

Giant hogweed is a biennial herb that can grow 8-14 ft tall. Plants sprout in early spring from forked taproots or seeds. Stems are hollow, and leaves are lobed. The best time to identify giant hogweed is when it is in bloom in June.

Garlic Mustard

Alliaria petiolata

Garlic mustard is a biennial herb that grows as a rosette of kidney-shaped leaves in the first year. The second-year plant can grow multiple stems up to 4 ft. with triangular, sharply-toothed leaves. In May, four-petaled, white flowers grow in clusters at the top of the stem. Garlic mustard produces a multitude of seeds, which can remain viable for seven years or more.

Flowering Rush

Butomus umbellatus

Flowering rush is a perennial, herbaceous, aquatic plant that grows 1-4 ft. tall, on an erect stem. The narrow, pointed leaves are triangular in cross section and have smooth edges and parallel veins.

Floating Primrose Willow

Ludwigia peploides ssp. glabrescens

Floating primrose willow is an aquatic perennial species that floats on water or sprawls along mud in wet environments. It is one of WNY PRISM's approaching region priority species. Keep a lookout!

Fishhook Waterflea

Cercopagis bengoi

Fishhook waterfleas are tiny crustaceans less than 1/2" long with long, sharp, barbed tails. The fishhook waterfleas have a slender spine and prominent S-shaped loop on the tail. Fishhook waterfleas collect in gelatinous globs on fishing equipment and lines.

European Frog-bit

Hydrocharis morsus-ranae

European frog-bit is a free-floating, short-lived perennial. The leaves are leathery and round with undersides that may be dark purple. Flowers are white with yellow centers, and bloom in the summer.

European Crane Fly

Tipula paludosa

Commodity:

Hayfields, pastures, turf grass, vegetable and small fruit crops

First sighting:

Erie and Niagara (2004)

Impacts:

Larvae (leatherjackets) feed on roots of hay, pastures, turf grass, sugar beets, turnips, and carrots, damaging growth of the plants.
Larvae also emerge to feed on stems and grass blades on damp, warm nights. Damage can also occur on golf greens from birds pecking out the larvae during the spring.
