An invertebrate survey of Llangennith Moors 2018
Llangennith Moors grazing marsh lies at the extreme western end of the Gower Peninsula. Before this survey, the invertebrate interest of the site was little known, with the only previous survey having been carried out in July 1991 which had a focus upon Diptera. Due to the minimal invertebrate knowledge of the site and relative absence of ditch maintenance there since the 1990s, Natural Resources Wales commissioned a survey of ditch and fen invertebrates and a search for two whorl snails of European importance, the Narrow-mouthed Whorl Snail Vertigo angustior (which is found on the nearby Whiteford Burrows and Oxwich Burrows) and Desmoulin’s Whorl Snail Vertigo moulinsiana, which is found in similar habitat on the south Llŷn coast in North Wales. The surveys were aimed at determining the current invertebrate interest of Llangennith Moors following a sea wall breach and subsequent managed retreat at Cwm Ivy Marsh and the loss of grazing marsh to saltmarsh. The Llangennith surveys were undertaken simultaneously by two surveyors in October 2018.

NRW commissioned a survey of the ditch invertebrate fauna in Autumn 2018. Survey work was undertaken by two contractors on 15th and 16th October 2018. The site is divided by the ditch network into several fields. These fields were each assigned a survey unit code, which was used as the basis for recording the invertebrate fauna. Many of the fields supported species-poor, improved, or semi-improved grassland of low ecological interest. The ditch network was mostly composed of ditches that were dried out or completely choked with tall emergent vegetation. As these improved fields and choked ditches had only a relatively low potential to support important wetland invertebrate assemblages, they were not the subject of more detailed follow-up invertebrate survey. Rather, survey effort was targeted towards those areas of the site that had semi-natural fen or marshy grassland and/or more open ditches with permanent standing water.
