If you get an aerial view of a salt marsh, you can easily recognize common cord-grass vegetation by the snake-like line running across the marsh. This grass first grows where former meandering saltwater creeks once flowed. The scientific name for this species of cord-grass is Spartina anglica, which refers to its English origin. It is a hybride between an English and North American cord-grass species and originated in the second half of the 19th century. Its common nickname nowadays is 'marsh pest', thanks to its aggressive growth on salt marshes. However, before it became a pest, it was purposely planted to help advance mud deposition in salt-marsh works.
