    "name": "Survey of the Tentacled Lagoon Worm (Alkmaria romijni) at Carew Castle Mill Pond (2006)",
    "description": "The tentacled lagoon worm (Alkmaria romijni) is a nationally scarce protected species found in lagoonal habitats in the Pembrokeshire Marine Special Area of Conservation. In Wales it has only been recorded from two saline lagoon sites in Pembrokeshire: Neyland Weir Pool (Westfield Pill) and Carew Castle Mill Pond. Elsewhere in the UK it had been recorded from only a handful of sites in lagoons and estuaries along the English Channel and southern North Sea and internationally between Morocco and the Baltic where it is not uncommon. A. romijni is limited to brackish water habitats and threats to these habitats include agricultural run-off and sewage, coastal development and coastal defence as well as pollution from industrial discharges. \r\nThere were three main purposes of this data capture: \r\n- To establish a repeatable baseline survey of the tentacled lagoon worm (Alkmaria romijni) at Carew Castle Mill Pond. \r\n- To undertake a spatial survey of salinity at the sediment-water interface \r\n- To note field observations on the integrity of the inflow/outflow system or any activities at the site that might be considered to have an adverse effect on the integrity of the site as a saline lagoonal habitat.",
