What happens to forests when invasive insects win?

Emerald Ash Borer will likely kill 99% of the ash trees in North America. We can't stop it. So what happens next?

At The New York Times, you can read a story I wrote about why we will lose the battle against the Asian beetle Emerald Ash Borer and what that loss is teaching scientists about the complicated ecological networks that make up forests.

A 2009 study in the journal Biological Invasions listed 43 native insect species that rely on ash trees for food or breeding. Those insects are the food supply for birds, including woodpeckers.

"You end up with a different ecosystem that different species prefer and where the old ones can't do as well," said Kathleen Knight, a research ecologist with the Forest Service.
