Stewardship Snapshots and Past Events

Freeing the Ferns at Lily Bay

Sunday, February 4 - Lily Bay Natural Area hosted 22 volunteers at a Stewardship work party to Free the Ferns from invasive species, as well as remove ivy from trees and removing blackberries.  Volunteers came from Hillsboro, Oregon City, West Linn, Portland and Lake Oswego to lend a hand to Mother Nature. There were students from 4 high schools representing NLYM (National League of Young Men), a PSU college student, a boy scout, students from Hillsboro, adults from NE Portland, and local residents. The 3 Stewardship Gnomes hid in native species providing a learning experience as our youngest volunteers searched for them.

Planting Party at Southwood Park

Saturday, December 9 - The Friends of Southwood Park were joined by an enthusiastic group of about two dozen volunteers. They planted 200 ferns in record time with the help of Park employee Kyle Bateman. Kyle brought the Stewardship trailer and truck to the work party, and people from Lake Oswego and the Portland metro area helped to conserve this important Lake Oswego jewel and restored the natural habitat. They planted in an area that was previously cleared of invasives through the hard work of the Friends of Southwood Park volunteers.

Send in the Scouts!

Boy scouts from troop 413 helped nestle 200 native ferns into Hallinan Heights Woods on November 5th.
