The site, located close to the Nant Irfon National Nature Reserve, has unimproved acid grassland on which grow the small-white orchid, the fragrant orchid ("Gymnadenia conopsea"), the Greater Butterfly orchid ("Platanthera chlorantha") and the Wood Bitter-vetch ("Vicia orobus"). The site is grazed by Exmoor ponies.
