The clifftops from Gadger (Pen-A-Grader) to St Agnes Head comprises mainly maritime/coastal heath with occasional areas of turf. The heathland is ablaze from spring into summer with gorse and the changing colours of ling and bell heather with clumps of cross-leaved heath in damper areas.
In spring the headlands and turf areas also studded with magnificent displays of the blue star-like flowers of squill, a south western cliff speciality (St Agnes Head is an excellent spot for this) and this mixes with splashes of yellow from birdsfoot trefoil and dyers greenweed before yellow kidney vetch comes into flower followed by other cliff specialities such as sea campion and rock rose. Other interesting flowers such as heath spotted and southern marsh orchids may also be found in places as the spring advances.
Reptiles such as common lizards, slow worms and adders may also be found if looked for quietly and carefully in the heathland.
Birds such as stonechats and ravens, although not seabirds, are also characteristic of the cliffs and ever present through the year along with fulmars, shags and gulls and peregrines, kestrels and buzzards are often along the cliffs.
