Emerald Ash Borer Update for the New Year

Kicking off the new year with an update on a not so new invasive species, the emerald ash borer (Agrilus planipennis) (EAB). 

 

EAB was first detected in summer of 2002 in Michigan, near Detroit, and in winter of 2003 in Ohio, outside of Toledo. It has since spread through the buckeye state and has made its home in 36 states. As indicated on the map, some states have felt the wrath of EAB from north to south and east to west, while some have what we would call 'isolated infestations' - at least for now.

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...
