Description:

Fen, reedbed, relict sand dune, and rough pasture.

Ffrwd Farm Mire lies 4 m above sea level inland from the extensive Tywyn and Pembrey sand dune complex. It is the least disturbed remnant of the fenland, which once stretched from Kidwelly to Burry Port.

There is a transition across this site from relict sand dune and rough pasture through species rich fen to reedbed and open water. The wetland habitats support Marsh Marigold (3-6), Bog Bean (4-6), and Marsh Orchids (6-7), with a variety of scarcer plants such as Bird’s-foot (5-6), Floating Club-rush, Tubular Water Dropwort (7-9) and Water Dock, as well as RDB plants such as the near threatened Marsh Pea (6-8), and vulnerable Frogbit (7-8).

The open water habitats support a varied dragonfly population including the Hairy Dragonfly (5-6) and Variable Damselfly (6-7).

The Slender Ground Hopper (8-7) and Short Winged Conehead (5-8) occur in the drier habitats, and a handsome black and orange fenland hoverfly Tropidia scita (5-10, peak 6-7) can be seen feeding on the profusion of nectar rich wetland flowers.

The reedbed supports breeding Cetti’s Warbler, Reed Bunting, Reed Warbler, Sedge Warbler and Willow Warbler, with Mallard, Moorhen and Water Rail. Winter brings Snipe and Teal, with occasional visits from Bittern, Marsh Harrier and Peregrine. Water Vole has also been seen here.
