SHADOW Lake Nature Preserve


SHADOW offers community classes & events, taught by local environmentalists, Friday morning nature walks, Wilderness Adventure Field Trips, summer programs, and Wild Walks for non-school groups of all ages.


Protection of natural lands not only retains habitat for Washington’s native plants and wildlife, but also offers human benefits through ecological services like carbon storage, groundwater recharge, flood and drought mitigation, and storm-water filtration. 

SHADOW Lake Nature Preserve is committed to preserving and protecting vulnerable ecosystems in a rapidly urbanizing corner of King County.


SHADOW Lake Nature Preserve’s Restoration & Stewardship Programs help maintain and restore vulnerable habitat and ecosystems at the Nature Preserve that support native flora and fauna while providing educational stewardship opportunities to our community.

Come explore SHADOW’s unique ecosystems, today!

We are excited for his next adventure as...

No Mow May

In the PNW, April showers bring May showers. Our rainy springs play a vital role for our ecology, and as the days get longer and warmer, the grass starts to not so much crawl as leap up from the ground. (Queue the sound of thousands of roaring lawn mowers).  Around the same time, bumble bee queens and other native bees emerge from underground as temperatures rise, looking for their first meal in months. Plants,...

The science of spring

One of the most iconic phenomena in nature is the arrival of Spring. In temperate climates many species of plants lose their leaves in the fall (the season is named for just that reason), and then in spring leaves and flowers re-emerge. But why, and HOW? In answering the “why” question, I like to start by proposing the alternative. What if trees did not lose their leaves in the fall? Well, if the tree was somewhere that...
