13th Annual Watershed Wide Event results

Across 8 sites, we got a lot done!

In total we had 157 volunteers, including 58 youth, who came out to volunteer to steward the watershed. Together we planted 747 native plants, removed invasive plants from .9 acre; some of this was dense stands of invasives, and some of this was a larger area with sparser invasives. We also filled 12 bags of trash, and removed invasive vines from nearly 300 native plants (all trees, aside from 50 native shrubs & trees installed along a tributary)!

We also found salamanders, massive worms, a bird skull, and a kiddo lost their first tooth (no tool mishap involved)! 

  • At Tryon Creek State Natural Area with Friends of Tryon Creek, volunteers removed English ivy vines.
  • At Marshall Park with Portland Parks & Recreation, volunteers planted native trees & shrubs along a future trail corridor.
  • At Jackson Middle School with Westside Watershed Resource Center, volunteers planted native plants along a community pathway.
  • At Lake Oswego High School with Oswego Lake Watershed Council and the LOHS Green Team, volunteers planted native trees and removed invasive plants and trash.
  • At Lewis & Clark College with West Multnomah Soil & Water Conservation District and L&C Center for Social Change & Community Involvement, volunteers planted native trees and removed English ivy. 
  • At Lake Oswego United Church of Christ with Sound Native Plants, volunteers removed invasive weeds from a tributary and away from recently installed plants.
  • At Park Creek HOA, neighbors removed English ivy from their shared greenspace.
  • At Boonesferry Terrace HOA, volunteers planted native trees & shrubs and removed invasive plants from their shared greenspace.

Keep an eye on our Instagram in the coming days for photos & a recap from each site!
