The steep hill slopes support an extensive area of primary magnesian limestone grassland in which blue moor-grass, Sesleria albicans, is abundant. The rich assemblage of grassland species includes a number of rare and local species, bird's-eye primrose, Primula farinosa, adder's-tongue fern, Ophioglossum vulgatum, lesser club-moss, Selaginella selaginoides, and grass of Parnassus, Parnassia palustris, as well as an inland colony of sea plantain, Plantago maritima.[1]
Notable among the fauna is the Durham Argus butterfly, Aricia artaxerxes salmacis, a form which is only found in the magnesian limestone areas of Durham.
