Emerald Ash Borer

The ‘slow motion crisis’ that’s facing U.S. forests

Last week, a group of researchers published saddening news about "sudden oak death," spread by an invasive water mold, that has killed over a million trees in coastal California. The pathogen, they found, simply cannot be stopped — though it can still be contained, and the harm mitigated. But it is too extensively established now in California to eradicate.

U.S. must step-up forest pest prevention, new study says

Imported forest pests cause billions of dollars in damages each year, and U.S. property owners and municipalities foot most of the bill. Efforts to prevent new pests are not keeping pace with escalating trade and must be strengthened if we are to slow the loss of our nation’s trees. So reports a team of 16 scientists in a new paper published online today in the journal Ecological Applications.

The Emerald Ash Borer and other invaders

More and more often, we hear about the arrival of a foreign plant or insect that is wreaking havoc on our native ecosystems. Take, for example, the Emerald Ash Borer, which will likely decimate all the ash trees in our forests.

New Science Policy Exchange Project: Forest Pests and Pathogens

The Harvard Forest, in collaboration with the Cary Institute of Ecosystem Studies, has launched a new Science Policy Exchange project on forest pests and pathogens. This project addresses growing concerns about damage to trees, forests, and local economies caused by introduced insects. 

New York is a hotbed for damaging forest pests

When Chris Standley received a tip that some ash trees within the Mohonk Preserve might be infested by a devastating insect, he grabbed a drawknife and peeled away the bark.

Invasive species pose serious danger to humans

Are invasive species killing us? This question must sound a little over the top if you think that invasive species are just garden pests, but history is filled with examples where they've killed humans.

Trees invaluable to community

Dave Strayer and Gary Lovett sounded a warning about the looming local extinction of ash trees. This almost certain event is because of the spread of the emerald ash borer.

Ash tree faces die-off as Asian pest spreads

As you drive around Dutchess County this fall, try to get a look at the dusky yellows and purples of the ash trees, because they won't be around much longer.
