This is Spartina!
Spartina alterniflora, a grass that invaded the Pacific Northwest has destroyed native wildlife habitat, reduced water quality, slowed sediment flow and interfered with recreational activities. However, we're now seeing very little of this aggressive plant in our Port Susan Bay Preserve, thanks to the dedication of our many partners, including the WA State Department of Agriculture, Snohomish County Noxious Weed Control Board, Washington Department of Fish and Wildlife, WA Department of Natural Resources, Skagit County, Tulalip Tribal Nation, and EarthCorps.
