Tree Walk: Jordan Woods

Join us to learn how to identify some of the trees in the Cedar Mill area:  Douglas fir, Western red cedar, Alder, Oregon white oak, and six species of maple, From Jackie Husen Park we'll walk a paved trail that goes through the natural area above Cedar Mill Creek. We'll dip down into a ravine on a soft surface trail to a boardwalk to see creekside trees, travel to a walled overlook, then climb some steps to loop back to Jackie Husen Park through neighboring homes and a leafy corridor of maples. The Jordan Woods Natural Area is also home to a nature art installation.

Tree Talk Webinar:

Tree Ordinances: How Communities 

Can Protect Existing Trees During Development

Trees are typically regulated at the local level (City, County, HOA, etc.) with relatively few state or federal laws protecting trees. Each community decides, more or less separately, which trees can and can't be removed and what information is required in order to approve tree removals (permits). Depending on where in Washington County a tree is growing, there may be essentially no protection, a formal permitting process, or it may depend on why the tree is being removed.


Ryan Gilpin is Principle Consultant at Nidus Consulting a Portland based arboriculture and ecology consulting company. As a consulting arborist, Ryan has read and navigated hundreds of different ordinances, mostly related to construction across North America. Ryan will review with us: what he looks for in reading ordinances, some important details in the ordinances across Washington County, how these compare to other parts of North America, and how communities typically develop ordinances.

Tree Walk: Orenco Woods Nature Park

Join Treekeepers on a walk through the Orenco Woods Nature Park. The 44-acre park, co-owned by Metro and the City of Hillsboro, sits along Rock Creek, a major tributary to the Tualatin River.  A segment of the Rock Creek Regional Trail runs through the park over a majestic bridge.

A network of looped trails weave their way through the site providing visitors a walk through rolling landscape, open meadows, oak savannah, riparian habitat, forested areas and a glimpse at a variety of birds and wildlife. Although parts of the trails are paved, other parts are made of compacted crushed gravel which is firm and stable. Portions of some trails exceed 5 percent slope.

On our walk we will talk about the history of the site.  To conclude, bring your picnic basket to have your lunch while socializing with fellow tree lovers.
