Black Jetbead
Rhodotypos scandens
Black jetbead is a deciduous shrub that can grow up to 5 feet tall. It forms a dense shrub layer that shades out native species and restricts the establishment of tree seedlings. Black jetbead is one of our Data Gap Species Priorities for 2024.
Policemen’s Helmet, Himalayan Balsam
Impatiens glandulifera
Policemen's helmet is an annual herb that produces irregularly shaped, pink to purple colored flowers. Similar to other ‘touch-me-not’ species, this plant produces fruit that bursts at maturity when disturbed.
Burning Bush
Euonymus alatus
Burning bush is an invasive ornamental woody shrub that is easily recognized by its vibrant red fall foliage. This invasive species has been introduced into natural landscapes through escaping cultivation.
Wavyleaf Basketgrass
Oplismenus hirtellus subsp. undulatifolius
Wavyleaf basketgrass is a perennial grass with a distinctly hairy stem and leaf sheath. Its seeds grow in 3-5 pairs of spikelets with long awns (pointed tips) that produce a sticky substance to aid in dispersal.
Waterwheel
Aldrovanda vesiculosa
Waterwheel is an herbaceous carnivorous, aquatic plant that captures small, aquatic invertebrates using clamshell-type traps, similar to the venus flytrap. It floats just below the water's surface and has stems 2-8 inches long, with whorls of 5-9 leaves. Waterwheel rarely flowers, but when it does, the small, greenish-white flowers emerge from the water, while the fruit capsules are held underwater.
Beech Leaf Disease
Litylenchus crenatae mccannii
Beech leaf disease is a new threat to WNY and poses a serious threat to beech forests. Research is ongoing to learn more about the biology of this disease including its spread vectors.
Scotch Broom
Cytisus scoparius
Scotch broom is a shrub with small, pea-like yellow flowers that bloom from late May to June. It grows up to 10 feet tall and its green branches are sharply angled with five ridges.
Carolina Fanwort
Cabomba caroliniana
Carolina fanwort forms extremely dense stands that clog drainage systems and waterways, interfering with recreational activities. Dense stands also negatively impact native biodiversity.
European Cherry Fruit Fly
Rhagoletis cerasi
The European Cherry Fruit Fly has been found on sweet cherry trees along the Niagara River. This was the first U.S. detection of this species and has resulted in a quarantine of parts of Niagara County.
