Lake Wilderness Arboretum

The Lake Wilderness Arboretum Foundation (LWAF) is a nonprofit organization that is the steward for the Lake Wilderness Arboretum under a Joint User Agreement with the City of Maple Valley. We maintain the Lake Wilderness Arboretum in a way that preserves, protects, and displays Northwest ecosystems as well as cultivated landscapes. LWAF is managed by a Board of Directors that operates per a set of approved bylaws.

The Foundation's ongoing maintenance and improvements to forested areas, trails, and gardens help provide a setting where visitors can enjoy and study both natural and cultivated settings in an otherwise urban area. With the rapid loss of open space and environmental learning opportunities, the Arboretum trail system and gardens provide a unique opportunity for those who visit.

As part of our stewardship, the Foundation also promotes horticultural science and conservation and provides educational opportunities in those areas.
