Saying Goodbye To The Kojo Nnamdi Show
On this last episode, we look back on 23 years of joyous, difficult and always informative conversation.
An up-close view of the Emerald Ash Borer.
Roosevelt Island, which lies between D.C. and Arlington in the Potomac River, recently reopened after the removal of about 200 diseased trees that were under attack by an invasive bug species — the emerald ash borer. The problem isn’t limited to the island: the first emerald ash borer was detected locally in 2003 in Prince George’s County, Maryland. Since then, the ash borer has spread across the region attacking and killing ash trees, which are a significant part of the local tree canopy. Kojo talks with experts about the local battle against the ash borer and how people can protect the trees in their own yards.

Photos: The Emerald Ash Borer
Beautiful, but deadly, an Emerald Ash Borer emerges from a tree after completing larval development.
Legless Emerald Ash Borer larvae like these two easily move in firewood, logs, or branches.
Emerald Ash Borer larvae create serpentine galleries beneath the bark. By consuming cambium, phloem, and sap wood, the borer effectively girdles the tree condemning it to death.
Along the C & O canal, woodpeckers remove the outer bark of ash trees as they search for larvae of Emerald Ash Bores on which to feast. This results in telltale “blonding” of the bark, a key sign of EAB infestation.
Neighborhoods throughout Maryland are feeling the wrath of Emerald Ash Borer. In 2015 EAB came to college at the University of Maryland.
