As part of a much larger working farm, with well over 200 acres in times past, Gwaenynog now has 16 acres of pasture, woodland and marshland. There is a variety of visiting wildlife, including foxes and badgers, plus weasels and polecats; there's even been evidence of otters down in the wetland area. The birdlife is varied too, including barn and tawny owls, peregrines and sparrowhawks.
