Tree Walk: 
The Historic Jenkins Estate

Tucked into a wooded niche on Cooper Mountain, Jenkins Estate is listed on the National Register of Historic Places. The Main House was a summer home modeled after a hunting lodge built for the English royal family. 

Tualatin Hills Parks and Recreation staff will give us an introduction to Jenkins Estate before Laurette Nacamulli leads us on some of the trails of the 68-acre grounds that include native woodland and acres of gardens. We will strike out on paved and soft surface trails that lead into woods of Douglas fir, madrone, hazel, alder, hemlock, and Oregon ash. The grounds include a row of lovely old elm trees which are some of Oregon's Heritage Trees. 


After the walk, those who are interested can join us for lunch at the Vintage Room Restaurant at the Reserve Golf Course.

Tree Walk: 
Lowami Hart Woods Walk

Let's see many, many shades of green on St. Patrick's Day with a walk in Lowami Hart Woods. This rolling walk is approximately 2 miles on paved and unpaved trails, and includes about 20 stairsteps, and a short walk on streets. This park has an interesting history — it's the site of a former Camp Fire (formerly Camp Fire Girls) location. We'll see that along the walk — along with firs, madrones, boardwalks, Johnson Creek, wetlands, and likely some dogs being walked.  (You can bring yours if they're well-behaved.) Sign up to see the location.

Tree Talk:
Insect Pests That Bug Our Trees

Most insects are native and beneficial, but some types of insects become problems if trees become stressed. Christine Buhl, Phd, is a Forest Entomologist with the Oregon Department of Forestry. She will review some of the major native and exotic insect pests of urban and forest trees that affect our Washington County trees, such as the recently discovered Mediterranean Oak Borer and Emerald Ash Borers. Find out what they are, ways to identify them, and how to prevent them from spreading. Christine comments: “The healthier you can make your trees, the better they are going to be able to resist and tolerate invasive insects.”

This will be a hybrid event, with an in-person option at St Andrew Lutheran Church in Beaverton, or a ZOOM option.


December through March

Join Our On-call Ivy Crew

English ivy hangs on through winter at a time trees are particularly vulnerable--the invasive vines keep growing while trees are dormant, and the excess weight can increase risks for trees during winter storms.

Weather makes it hard to schedule events, so please, sign up and we'll notify you when there is a good weather window so we can schedule an ivy pulling event.


Wednesday, April 17, 6:30-8:00 pm
