Foulque macroule
The lake contains tench, European perch, common roach, northern pike, eels, common minnows and three-spined sticklebacks, and may have once been stocked for coarse fishing purposes. Birds breeding here include kingfisher, white-throated dipper, mallard, Eurasian coot, common moorhen and mute swan, and other birds, including the little grebe visit in winter. The moth "Donacaula forficella" was recorded from Bishops Pond, a first record for inland Carmarthenshire.
