Invasive Species Control

Streams, shorelines, lakes, and riparian areas are some of the most precious natural resources on the Tulalip Reservation. These critical water resources sustain habitat, fisheries, and the Tulalip people. Invasive plants threaten the integrity of these valuable natural systems, and can also cause public health concerns.

The Tulalip Reservation is known to contain a variety of harmful non-native plant species. The Natural Resources Department has worked closely with the Snohomish County, the Washington State Department of Agriculture, Washington State University, and others with invasive species control efforts. Significant work has also been done to identify and quantify the extent of reservation non-native plant infestations.

Primary invasive plant species of concern include:

  • Cordgrass (Spartina alterniflora)
  • Purple loosestrife (Lythrum salicaria)
  • Perennial pepperweed (Lepidium latifolium)
  • Common reed (Phragmites australis)
  • Bittersweet nightshade (Solanum dulcamara)
  • Giant hogweed (Heracleum mantegazzianum)
  • Japanese knotweed (Polygonum cuspidatum)
  • Scotch (Scot’s) broom (Cytisus scoparius)
  • Poison hemlock (Conium maculatum)
  • Tansy ragwort (Senecio jacobaea)
  • Canada thistle (Cirsium arvense)
  • English ivy (Hedera helix)
  • Yellow archangel (Lamium galeobdolon)
  • Field bindweed (Convolvulus arvensis)
  • Butterfly bush (Buddleja davidii)
  • Common periwinkle (Vinca minor)
