The Emerald ash borer (EAB) is an invasive beetle responsible for the loss of 100 million ash trees since its arrival in the US. EAB was spotted for the first time in Oregon this past summer in Forest Grove. Urban Forestry staff at the City of Portland are participating in a statewide task force and taking other steps to monitor and prepare for its arrival and spread. The City will be alerted once emerald ash borer arrives. However, you can help keep an eye out and monitor our local ash (Fraxinus spp.) trees using Urban Forestry’s new, interactive map.
This map was created to track where ash (Fraxinus spp.) trees are located and to monitor them for signs and symptoms of EAB. The map shows data from Urban Forestry’s Street and Park Tree Inventories, including over 700 ash trees found in city parks and more than 9,000 planted in the right of way. The map does not show the thousands of ash trees located on private property or in the city’s natural areas, like Forest Park. Remember, all North American Ash Trees in the Genus Fraxinus are susceptible to emerald ash borer. White fringetree (Chionanthus virginicus) and olive trees (Olea europaea) may also be at risk.
How can you help?
1. Check the map and see whether there are any ash trees near where you live, work, or play.
2. Learn to identify ash (Fraxinus spp.) trees, the emerald ash borer, and signs and symptoms of EAB.
3. Report observations of EAB or trees with symptoms by calling 1-866-INVADER or reporting online.
4. Don't Move Firewood! If possible, buy or obtain your firewood as locally as possible. Even moving firewood from one town to the next town could provide EAB with a free ride.
5. If you have ash trees or any of the trees listed as susceptible, take care of them. EAB is most attracted to trees that are stressed.
The City is already taking steps to prepare for EAB, stay tuned for more updates coming soon!

Celebrating this Year's Bill Naito Group Award Winner: No Ivy League!
| |
Each year, the Bill Naito Community Trees Award is presented on Arbor Day to an individual and a group that has exemplified the spirit of Bill Naito. Naito was the founder of the Urban Forestry Commission and a lifelong tree advocate. Award winners are recognized for their tireless work to care for, protect, and advocate for our community’s trees.
This year, the group winner is No Ivy League!
Since 1994, No Ivy League has worked to empower youth, educate the public, and remove English ivy from Portland's parks. No Ivy League's mission is to restore the native habitat of Forest Park and other natural areas. This includes removing invasive plants, youth development programs, environmental education, and community participation.
Removing invasive plants is not easy work. We are grateful to the many volunteers of No Ivy League who have done incredible work keeping Portland’s natural areas healthy.
