Invasive species: The impact of Emerald Ash Borer
The impact of invasive species on native species is hitting close to home where I live right now. Ash trees ( Fraxinus sp.) were popular shade trees in my area. However, that is changing rapidly. Wherever I drive, I see ash trees with dead tops and thick bunches of green leaves near the crotches of their main branches due to young sprouts. Classic signs of Emerald Ash Borer ( Agrilus planipennis ) infestation.
