The grasslands of the SAC contain a scattering of the green-winged orchid and two other orchids frog orchid and Common Spotted-orchid have been recorded from the site. These are mainly in the base-rich areas overlying the limestone. Over the sandstone at the summit of Clomantagh Hill there is a markedly different flora which includes more ling and other plants more typical of heaths. The SAC contains some woodland to its north west, mainly of [[Betula pubescens|downy birc] and [[Corylus avellanus|hazel]] which has a rich ground flora. The priority species that the SAC conserves is the green-winged orchid, a species listed in the Irish red data Book.
