Plant Introductions: Meet Invasive Species Common Barberry and Japanese Barberry

Common barberry or European barberry, Berberis vulgaris, is a non-native invasive woody shrub.  Intentionally brought to North America by early settlers in the 1600s, it has escaped cultivation and is widely distributed in the northern U.S.  Common barberry is also an alternative host for the disease, black stem rust, a severe pest of grains.  As a result, large scale eradication efforts began in the 1900's to remove this reservoir of disease.  However, populations still exist in the Great Lakes states, including Ohio, and the northeastern United...

Invasive of the Week - Phragmites (Phragmites australis)

Phragmites is a non-native perennial grass this is commonly referred to as common reed. The wetland grass thrives in its name sake - wetlands or low areas - but can also establish itself in other areas. It is commonly found along roadsides in ditches, in retention ponds and bioswales, along the edges of ponds, rivers and lakes, and will completely infiltrate a wetland, quickly becoming a monoculture - single species. It is considered invasive as it outcompetes all other plants and displaces wildlife as it becomes the top-plant, at least in numbers, in a given area.
