Spartina anglica

---

---

Origin and Distribution:

• This species developed in the south coast of England after the introduction of the non native species S. alterniflora.
• It is believed that S. alterniflora arrived in Britain via contamination of ballast water or sediment.
• Non native Spartina species also represent a significant risk to mudflat habitats in North America as well as in Europe.

---

Impacts:

• The primary habitat of this species is just below the regular salt marsh communities and in the areas occupied by intertidal Zostera. This is of significant concern to environmental managers as certain species of birds such as the Brent geese depend on this habitat for food.
• The spartina swards are also cited as creating monocultures.

How did it get here?

• This species was initially planted in Northern Ireland to stabilise dunes.
