azoricum and shore dock Rumex rupestris. The liverwort Petalophvllum ralphsii is nationally scarce and occurs in some dune slacks whilst on Llanddwyn Island the nationally rare golden hair lichen Teloschistes flavicans has recently been found. Golden samphire Inula crithmoides is also found on the island, most commonly on the path leading to the larger lighthouse. Other interesting plants include dune pansies (Viola curtisii), sea spurge (Euphorbia paralias and Euphorbia portlandica), and sand cat's-tail (Phleum arenarium). and in the dune slacks, creeping willow (Salix repens) and a variety of orchids including the marsh orchid (Dactylorhiza purpurella), along with butterwort (Pinguicula vulgaris), grass of parnassus (Parnassia palustris) and yellow bird's-nest (Monotropa hypopitys) can be seen. In the last decade, the round-leaved wintergreen (Pyrola rotundifolia) has spread across much of the dune system. Animals Birds common to the dunes include herring gulls, oystercatchers, lapwings, curlew, skylarks and meadow pipits. The dunes are also home to toads and lizards as well as many species of insects. The Warren was featured on the BBC TV programme Autumnwatch in November 2008 in a feature showing the importance of ravens to the area.
