Kiwanis Memorial Preserve Park Restoration
Parks and Green Spaces Levy Project Information


Address: 36th Ave W and Ohman Place W

Project Status

Thank you Seattle! Over four acres of invasive vegetation was removed! We have now enrolled all of Kiwanis Ravine in restoration, and will focus this year on the establishment of native plantings and continued monitoring.

A copy of the March 2012 final report prepared by EarthCorps is available below.

Kiwanis Memorial Preserve Park, habitat to the largest colony of herons in Seattle, is threatened by aggressive non-native weeds.

Invasive plants such as English ivy, Himalayan blackberry, English holly, Knotweed, and Clematis grow faster than our native plants, leaving behind what biologists call an ecological "dead zone," unable to provide habitat for native wildlife or perform many of the green functions our city relies on. Vines climb up into the canopy, covering leaves and blocking photosynthesis. Understory invasives choke out native plants on the ground and prevent new seedlings from regenerating the canopy.

With the new funding from the Parks and Green Spaces Levy multiple restoration techniques will be available along with follow up monitoring and control.

36th Ave W and Ohman Place W
The Parks and Green Space Levy
allocates $600,000 to restore habitat.

Project Description

The project includes removing invasive vegetation and replanting / reseeding with native species, planting native trees, installing temporary erosion control measures, follow-up invasive control, and establishment watering. The restored habitat will continue to be monitored and maintained as part of the Green Seattle Partnership. For more information, contact Rory Denovan.

Community Participation

Heron Habitat Helpers, Seattle Parks and Recreation, EarthCorps and community volunteers, have made great inroads towards restoring the habitat in Kiwanis Memorial Preserve Park.
