Monitoring the Gipsywort Weevil Datonychus arquatus on Pembrey Air Weapons Range in 2022
The Black Bog Ant Formica picea is rare in the UK where it is associated with bogs and wet heath at a small number of sites in southern England including the heaths of Dorset and Surrey and the valley bogs in the New Forest, with a single site in Yorkshire. In Wales, it is restricted to Rhossili Down on Gower, Cors Goch Llanllwch in Carmarthenshire and Cors Llanerch in Pembrokeshire. It was first recorded on Rhossili Down in 1913 and subsequently refound in 1996. A survey in July 1997 found 49 active nests along four east to west-oriented transects across the bog and flushed wet heath habitats to the east of the central ridge, with a further 23 active nests elsewhere on the site. It was estimated thatbetween 840 and 4970 active nests were present across the site, representing the largest population in the UK. The current survey in August 2022 repeated the 1997 work, with a count of active nests along the four transects. A total of 47 active nests was recorded, two less than in 1997, although numbers along each transect varied

The technique used to record Black Bog Ant along the transects was a modified form of that employed in the 1997 survey. For each of the four transects, a strip approximately 10 metres wide centred on the appropriate grid line, was searched intensively following the method used on Cors Goch Llanllwch by Fowles & Hurford (1996). To facilitate recording, the transect was divided into ten-metre sample sections, each of which was assigned a unique sample number, starting at the western end of the transect.
