Species Profile -- Japanese Spiraea
USDA. NAL. National Invasive Species Information Center.
Japanese spiraea is a perennial, deciduous shrub that can rapidly take over disturbed areas. Growing populations creep into meadows, forest openings, and other sites. Once established, spiraea grows rapidly and forms dense stands that outcompete much of the existing native herbs and shrubs. Seeds of Japanese spiraea last for many years in the soil, making its control and the restoration of native vegetation especially difficult. A single plant produces hundreds of small seeds that are naturally dispersed by water and deposited along stream banks.

Species Profile -- Japanese Stiltgrass
USDA. NAL. National Invasive Species Information Center.
Japanese stiltgrass is a highly agreessive annual grass capable of colonizing a wide variety of habitats. It threatens native plants and
natural habitats in open to shady, and moist to dry locations.
Stilt grass spreads to form extensive patches, displacing native
species that are not able to compete with it.

Species Profile -- Japanese Climbing Fern
USDA. NAL. National Invasive Species Information Center.
Japanese climbing fern is an invasive exotic vine, native to eastern Asia. Japanese climbing fern can overtop forest trees, thus shading-out and killing them. It is often found as a tangled mass over shrubs and fencelines, smothering ground cover and tree seedlings.

Species Profile -- Air Potato
USDA. NAL. National Invasive Species Information Center.
Air potato is a member of the yam family and native to Asia and sub-Saharan Africa. This versatile plant invades a variety of habitats, including pinelands and natural area hammocks. It can quickly engulf native vegetation in natural areas, climbing high into mature tree canopies. The vines produce many bulbils, allowing the plant to spread quickly. Air potato is extremely difficult to eliminate because new plants sprout even from very small bulbils and underground tubers.

Species Profile -- Witchweed
USDA. NAL. National Invasive Species Information Center.
Witchweed (Striga asiatica) is a parasitic plant that attacks some of the most important crops in the United States -- corn, sorghum, sugar cane, and rice. It also parasitizes certain weedy grasses. Unlike most weeds, which merely compete with crops, parasites like witchweed do their damage more directly. They rob nutrients and moisture by
tapping directly into the host’s root system. Consequently, the host spends energy supporting witchweed growth at its own expense.

Species Profile -- Princess Tree
USDA. NAL. National Invasive Species Information Center.
Princess tree, also known as royal pauownia or empress tree, is a small to medium sized tree native to China. It is an aggressive ornamental tree that grows rapidly in disturbed natural areas, including forests, stream banks, and steep rocky slopes. Its ability to sprout prolifically from adventitious buds on stems and roots allows it to survive fire, cutting, and even bulldozing
in construction areas.

Species Profile -- Old World Climbing Fern
USDA. NAL. National Invasive Species Information Center.
The Old World climbing fern is an invasive exotic vine in Florida, native to Asia and Australia. This species is climbing into trees and shading out native vegetation in
hundreds of acres in east-central Florida. Old World climbing fern has the
ability to "resprout" from almost anywhere along each climbing leaf and increases fire risk by allowing fire to spread up trees along its vines.

Species Profile
-- Oriental Bittersweet
USDA. NAL.
National Invasive Species Information Center.
Oriental bittersweet is an aggressive invader that threatens
vegetation at all heights in forested and open areas.
Oriental bittersweet grows fast; it can cover tall trees
in a season, causing them to collapse from the weight
of the vines. Understory plants are smothered by the
vines themselves or by lack of light.
