Environmental Stewardship & Volunteer Appreciation Day

Bring your gloves and work gear, help us weed, mulch and plant, then party with your co-workers on May 18 at Lake Sammamish State Park.

To celebrate park volunteers, Friends of Lake Sammamish State Park, Mountains to Sound Greenway Trust, and Washington State Parks are hosting a volunteer day of environmental stewardship followed by a picnic celebration, 10 a.m. to 2 pm.

Morning activities will include habitat restoration including weeding and invasive species removal. Then volunteers will be treated to educational tours, games, lunch and more!

Everyone is welcome and all training will be provided. Participants under 13 years old must be accompanied by an adult. Volunteers help ensure that Lake Sammamish State Park will continue to provide important habitat for several species of salmon, many birds — including bald eagles, great blue herons, and red-tailed hawks — and a wide variety of amphibians, insects and other wildlife.
