State Asks You to Check Trees for Invasive Forest Pests in August
OLYMPIA – Four state agencies and a university are asking residents to check trees in their yards for harmful bugs as part of the national Tree Check Month in August.
August is the peak time of year to find invasive bugs like Asian longhorned beetle, emerald ash borer and other aggressive wood-boring insects.
“Invasive insects can destroy Washington’s forests.” said Justin Bush, executive coordinator of the Washington Invasive Species Council. “In Washington, more than 22 million acres of forests are at risk from invasive insects and disease. We need everyone’s assistance to prevent these damages in Washington State.”
The Washington Invasive Species Council, Washington State Department of Agriculture, Washington State Department of Natural Resources, and Washington State University Extension are asking residents to take ten minutes to go outside and inspect their trees. Invasive wood boring insects typically emerge from trees in August. Experts also suggests that all pool owners should check their pool skimmers and filters for the invasive bugs. Emerging adult insects often end up as debris collected in pool filters.
If residents see any invasive insects or signs, they should to take photographs and report the find immediately at www.invasivespecies.wa.gov/report.shtml, where they can get an online reporting form or download the free WA Invasives mobile app.
“Initial infestations are difficult to detect, so early detection and reporting is critical to rapidly manage new populations,” Bush said. “Our state needs help finding new outbreaks so they can be contained quickly and eliminated.”
“Early detection and rapid response is the more effective and cost-efficient approach to managing new invasive species, whether because we have the opportunity to eradicate it or because we can take steps to quickly limit their impact,” said Dr. Chris Looney of the Washington State Department of Agriculture. “Our own data show that the general public is an important source of first detections.”
First indications of invasive insect damage to trees include sudden die back or death among a group of like trees that are otherwise vigorous and healthy. If you see this, investigate further and look for sawdust, exit holes or actual beetles. You might help find one of these invasive species:
Need help recognizing suspicious beetles?
“Each county has a WSU Extension Office and Master Gardener Program that can help identify suspect beetles,” said Todd Murray, director for Washington State University Extension Agriculture and Natural Resource Unit. “And if they can’t, they know the specialist to send it to. Master Gardeners are often the first ones to recognize and report a newly introduced insect pest. Master Gardener clinics receive a large number of insect samples at this time of year.”
“When it comes to the health of your trees, a few minutes checking them for insects can make a big difference,” Bush said.

National Invasive Species Awareness Week!
Invasive species cause millions of dollars of damage every year to our agricultural, cultural, and natural areas. They crowd out native species and are a huge detriment to biodiversity.
One of the best ways to combat invasive species is to prevent their establishment in the first place. So when you are out enjoying all Skamania County has to offer, take a few steps to do your part in preventing weeds from invading your favorite trail or park:
1) Brush your boots, bike, or gear before and after you recreate
2) Keep pets leashed and stay on the trail
3) Volunteer to help remove invasive plants in your favorite natural area
4) Report any invaders to your local Noxious Weed Program
5) Tell your friends about how to prevent invasive species!
The Washington State Noxious Weed Control Board and the Skamania County Noxious Weed Control Program are offering free seed packets containing a non-invasive, pollinator-friendly flower mix! For more information and a complete list of the species included in the mix, click here. Also, contact the Skamania County Noxious Weed Program to get your free packet today!

2016 Noxious Weed List for Skamania County has been adopted!
Every year, county weed boards review the state weed list and create a county-specific list based on local conditions and priorities. In addition to ALL Class A species and all Class B species designated for control by the state, the county weed board requires control of certain Class B and Class C species that are a local priority.
The Skamania County Weed Board adopted the 2016 weed list after a public hearing on February 3th. Those species selected are required, by law, to be controlled. Those not selected are still considered noxious weeds and a threat, and should be contained or controlled when possible. For more information on the state or county noxious weed lists, please call the Skamania County Noxious Weed Control Program.
