It’s Lake Wilderness Arboretum Foundation’s 50th anniversary – a celebration that started with a small group of local residents establishing a nonprofit dedicated to finding a place in south King County to establish an arboretum. In an initial partnership with King County Parks and Recreation and later with the City of Maple Valley, volunteers took the lead in establishing the gardens and collections, trail access to 26 acres of preserved native forest, and the nursery area that is now known as Lake Wilderness Arboretum.  Since its establishment in Maple Valley, Foundation volunteers have also taken on a major role in the maintenance of these 42 acres.

Pay it forward: Volunteer to spend some time to be a part of the Foundation’s efforts to enhance its programs and Lake Wilderness Arboretum for the next 50 years.

The educational opportunities that Lake Wilderness Arboretum offers to its visitors and volunteers are huge. One way to pay it forward and to learn more about the Arboretum, its gardens and sound gardening practices is to join the Lake Wilderness Arboretum docent group.

Docent training continues with meetings/training scheduled on the first and third Thursdays of February through April and on the third Thursday only from May through October. Meetings begin at 12:30 p.m. in the Arboretum’s Nursery. Volunteers spend approximately three to six hours per month for training, tours and presentations. You don’t need to be an expert already; you will learn from our program and established docents.

For more information on our docent program or Lake Wilderness Arboretum, please contact the Arboretum at info@lakewildernessarboretum.
