Emerald Ash Borer

Emerald Ash Borer beetles haven’t been identified in Eugene, yet. But the city’s foresters know the destructive insect will eventually get here, and they’re making plans to manage its effect.

The destructive Emerald Ash Borer beetle has been increasing its range in the U.S. for decades.

An invasive, tree-killing pest has made its way to Portland, spelling trouble for the many native ash trees that cool residential neighborhoods on hot summer days.

Oregon State University Extension is looking for volunteers to collect Oregon ash seeds.

This summer, the invasive emerald ash borer beetle was found in four Oregon counties. So far, none have been detected in Oregon State Parks, and the parks department wants to keep it that way for as long as possible.

Invasive emerald ash borer beetles are threatening ash trees in three more counties across the Willamette Valley.

Oregon forestry officials have collected over 900,000 seeds from a native tree species, in an effort to protect against an invasive insect.

It’s taken 20 years, but the most destructive insect in the country has been found in Oregon.
