    "name": "The Feasibility of the Eradication of the Non Native Species Devil's Tongue Weed (Grateloupia turuturu) in Wales - Milford Haven Survey July 2013",
    "description": "Grateloupia turuturu, Devil's tongue weed is a Non Native Species (NNS) now found in the UK. Devil\u2019s tongue weed grows in sheltered areas including harbours and bays, attached to pontoons, harbour walls, shells and stones. It occurs on the lower shore in pools, and subtidally to 7 m. Due to its tolerance of low salinities it may be found in estuarine areas as well as fully marine waters. \r\n\r\nA survey was undertaken to search for and record the presence of G. turuturu within Neyland marina and the surrounding Milford Haven area. The results showed that 38% of the pontoons and other floating structures surveyed in Neyland marine and wider Milford Haven waterway had a presence of G. turuturu. It is postulated that Neyland marina provides a suitable environment for reproduction of G. turuturu and introduction may have occurred through ship ballast water and/or the import of live shellfish associated with local aquaculture. \r\n\r\nThe purpose of this survey was to assess the extent of dispersion of G. turuturu in Neyland marina and the wider Milford Haven waterway with the purpose of establishing whether eradication of this species was feasible. Information on the extent, density and dispersion of G. turuturu in the Milford Haven waterway may also influence future management responses to this and other marine non-native species. Recording the extent of G. turuturu informs future management response and helps decide the feasibility of eradicating the species.",
