Pendleton, Oregon – Hikers and anglers heading to McKay Park, the Umatilla River Trail and nearby state recreation areas this spring are being urged to act immediately if they spot a destructive invasive beetle capable of killing hardwood trees across the Pendleton area.
According to the U.S. Forest Service and the Oregon Department of Agriculture, the Asian longhorned beetle attacks maple, birch, willow, poplar and elm trees. Officials warn that infestations can spread quickly along river corridors and in clustered park settings if not reported early.
Hardwood trees line stretches of the Umatilla River, shade walking paths in McKay Park and dot residential neighborhoods throughout Pendleton. These trees help stabilize streambanks, reduce summer heat and provide habitat for birds and wildlife common in Eastern Oregon.
The beetle is glossy black with distinct white spots and long black-and-white banded antennae that extend beyond its body. Signs of infestation include perfectly round exit holes in trunks, sawdust-like material collecting at the base of trees and thinning or dying branches high in the canopy.
If left unchecked, weakened trees could drop limbs during windy spring systems, creating hazards along trails and picnic areas.
Officials urge residents and park visitors to kill the beetle on sight if safely possible and report sightings immediately to state agriculture authorities. Early reporting this spring could prevent widespread tree removal and protect Pendleton’s riverfront parks into summer.
