Friends Groups

Information
Friends groups are made up of volunteers, neighbors, coworkers, and park lovers who come to a natural area or park on a regular basis (sometimes monthly, sometimes quarterly) to do hands-on restoration with the support of Portland Parks & Recreation staff.

What is a Friends Group?
Friends groups are made up volunteers, neighbors, coworkers, and park lovers who come to a natural area or park on a regular basis (sometimes monthly, sometimes quarterly) to do hands-on restoration with the support of Portland Parks & Recreation staff. While activities vary with the seasons, friends groups are regularly involved in removing invasive weeds, planting native plants, building fences and maintaining trails, picking up litter, monitoring plants and wildlife, and more! PP&R supplies the gloves, tools, training, plants, and snacks and the friends group provides the people, smiles, laughs, energy, and advocacy for the long-term health and beauty of Portland's parks and natural areas.

Friends groups are the heart of many of our natural area parks!
Get to know some of our existing friends groups below. You can see where they work, what their goals are, who is involved, and what the schedules are for restoration events and meetings.

Don't see a friends group for your favorite natural area? Interested in starting one with a group of your neighbors? Contact us and we will help you make it happen!
