Britain's sea cliff slops and the seaward sectors of coastal valleys contain exceptionally rich wildlife habitats. In generic terms they can be called 'coastal slopes'. They support a diverse and often specialist flora which occurs in various grassland, heathland, wetland, woodland and scrub communities. They also have a significant breeding bird fauna which is distinct from that of steep sea cliffs, as well as a wide diversity of invertebrates, many of which are thermophilous ('warmth-loving) specialists which are largely or wholly restricted to coastal habitats.
