Lake Oswego Watershed Council
Let’s Branch Out and
Talk Trees Together!
The Tree Summit is in partnership with the Oswego Lake Watershed Council, the Lake Oswego Sustainability Network, the Mountain Park Homeowners’ Association, and 14 neighborhood associations.
English ivy (Hedera helix) may conjure up images of cozy, country cottages, but don’t be deceived. This invasive weed can destroy buildings, poison pets, and topple trees.
Be a part of the solution. There are many ways to help protect watershed health at home.
The links on this page provide useful information to help you improve water quality and wildlife habitat in your yard and your community.
Watershed Councils work with our community members, building a sense of place while together stewarding the land and water. This giving season, we’re collaborating to encourage each of you to connect with the Portland Metro area Watershed Councils where you live, work, and play!
Volunteer with us to steward our natural resources with your community! Upcoming events linked below!
