Treekeepers of Washington County programs
We work to protect and advocate for trees in urban unincorporated Washington County. Don’t miss our upcoming events! All events are free. Visit the Treekeepers website to learn more.
Webinar: Trees as green infrastructure
Wednesday, May 6, 6:30-8 pm, online via Zoom
Changes in land use and urban development affect watershed hydrology and tree canopy. Natural area protections, green stormwater infrastructure, and stream corridor enhancements help offset development impacts and protect local waterways. Elle Worrlein and Lindsey Obermiller, both with Clean Water Services (CWS), will join us to discuss urban stormwater management and vegetated corridor protections. Registration is required to attend.

Tree Walk: Hoyt arboretum
Thursday, May 7, 10-noon, Hoyt Arboretum
Join Sue Rosenbaum to experience spring blooms around Hoyt Arboretum. We’ll start at the Visitor Center with a little background on the Arboretum and its mission, then walk through the oaks and beeches before arriving at our nationally recognized magnolia collection. After spending some time among the magnolias, we’ll explore the flowering plants of the Rosaceae family and finish with a visit to the viewpoint for a glimpse of Mt. St. Helens and then return to the visitor center. Register now as space is limited.
Tree Walk: Summerlake Park

Saturday, May 9, 1-3 pm, Summerlake Park
Summerlake Park is home to songbirds, ducks, and other aquatic animals. There is a beautiful Rhododendron garden and shaded, wooded areas. Join Liz Saufley on this one mile paved trail as she highlights amenities for adults and children. We’ll be moving at a “botanical pace,” meaning we will probably walk slowly and stop often to fully enjoy our surroundings. Register for the walk here.
Cedar Mill Garden Club
This season you won’t find the Cedar Mill Garden Club meeting indoors at the Beaverton Library. From May until fall, we will be out and about enjoying tours, taking trips to nurseries and local gardens, attending plant sales, and maintaining our pollinator plot at Leedy Grange. Anyone interested in gardening, whether experienced or a beginner, is welcome to join us. For more information, please contact Cathy Ramsey at cathyramsey308@gmail.com or 503-866-4222.
