If so, let the land manager know! Spartina is a rapidly spreading introduced grass species which was first introduced to stabilise estuarine mudflats, reclaim land and prevent shoreline erosion. Spartina, a declared noxious aquatic weed species, is now known to be a major environmental threat to estuaries, causing siltation and impacts on the biodiversity of native salt marsh and seagrass. It also affects the habitats of migratory bird species and near shore marine animals.
