The site is of interest for both geological
and biological features. The geological feature of this site is the
assemblage of landforms that occurs in the area around Carn Meini,
where there are large number of rocky crags or tors developed
mainly on a volcanic rock known as dolerite. The unenclosed common
grazings of Mynydd Preseli, topped by numerous cairns or tors of
hard igneous rock, are of special biological interest for their
wetland, heathland and grassland vegetation and the many associated
rare plants and animals.
