Department of Forestry warns imported trees may be infected with invasive species and should be disposed of differently

The Woodburn Public Works Department is hosting free drop-off recycling for Christmas trees through Monday, Jan. 14.

All Christmas trees must be free of decorations, including tinsel for drop off at the parking lot on Second Street behind the Woodburn Post Office between Lincoln Street and Grant Street. The drop-off site will be open from 8 a.m. to 3:45 p.m. on Monday through Friday, at 9 a.m. to 1 p.m. on Saturdays.

The drop off is in conjunction with Republic Services, which is offering pick-up service for Woodburn residents who are unable to drop off their Christmas trees. Contact Republic Services at 503-981-1278 for curbside pick up.

But the Oregon Department of Forestry has issued a warning that imported trees may be contaminated with an invasive species and need to be disposed of more carefully.

Many trees shipped from North Carolina to the west coast have come infested with the larva of elongate hemlock scale, a variety of insect which overwinters its eggs on the underside of evergreen needles. Also known as the fiorinia scale, the insect can be identified by its flattened, light yellow brown to brownish orange waxy cover of the adult female, which is about 1.5 mm long.

The insect feeds on the undersides of needles and attacks a variety of evergreen trees.

While the Oregon Department of Agriculture ordered the infested trees destroyed when the insects were found, some trees had already been sold to the public.

The Oregon Department of Forestry is asking residents who bought a Christmas tree from a national big box retail chain to avoid throwing the tree into the woods or yard compost, and instead cut it up and seal it in trash bags for disposal.

Those who have found elongate hemlock scale on their Christmas trees are asked to contact the Oregon Department of Forestry's Forest Health Unit at This email address is being protected from spambots. You need JavaScript enabled to view it..
