Species Profile -- Sacred Bamboo
Sacred Bamboo was introduced as an ornamental. It colonizes by spreading underground root sprouts and by animal-dispersed seeds, and may displace native species. It is difficult to remove manually because even the smallest piece of root
will re-sprout.
* See our Plants section for more information and additional species profiles.

Species Profile -- Japanese Barberry
Japanese barberry was introduced as an ornamental and promoted as a replacement for common barberry (Berberis vulgaris), which is a host for black stem rust. Japanese barberry forms dense stands that compete with native trees and herbaceous plants.

Species Profile -- Common Buckthorn
Common buckthorn is an invasive plant introduced to the U.S. in the early 1800s (or possibly earlier) as an ornamental plant. Common buckthorn forms dense stands that dominate ecosystems and displace native species.

The Forest Inventory and Analysis program of the USDA Forest Service has created a series of downloadable invasive plant distribution maps for its Northern Region (includes 24 states). The distributions on these maps portray the spatial distribution of the plants based on observations from the FIA program. Check out our Plant Species Profiles which now includes this data.

Species Profile -- Fig Buttercup
USDA. NAL. National Invasive Species Information Center.
Fig buttercup is low-growning perennial herb. It out-competes native plants through it's extremely early seasonal growth and forms extensive carpets in natural areas, crowding out native plants. Fig buttercup is aggressive and spreads rapidly once established.

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.
