Spartina is the only grass species found in the inter-tidal zone apart from the small native non-grass Zostera. Tall fescue, couch and other grass species are similar to spartina but none of these are found in the intertidal zone.
Spartina is a perennial, clump-forming grass to 1 m with rhizomes and fibrous roots and erect stems with many brownish leaf sheaths. Seedheads are occasionally seen, and seed is occasionally produced at some sites.
Spartina is controlled by the Department of Conservation - contact your local DoC office for more information.
