Wildlife of the Cliffs
Because of its coastal location the reserve area
can usually provide something of interest for the birdwatcher. In spring
it is a good place to look for migrants. The valleys provide cover for
small migrants such as the common warblers, spotted flycatcher
and redstart. Species such as pied flycatcher and sedge,reed
and grasshopper warbler put in less regular appearances.
The open grasslands are good places for wheatear,
whinchat and stonechat while hobby, turtle dove
and cuckoo are also regular passage birds.
Most of the huge spring passage of water birds in
the Channel passes far out to sea but some species such as the common
sandpiper and sandwich tern are annual visitors and occasionally
the passage of others such as common tern,Artic skua, whimbrel
and bartail godwit can be seen from the shore.

During the breeding season the area is home for several important
species. Probably the most important is the large colony of cormorants
breeding on Gad cliff.

Gad cliff is home too for other impressive species such as the
peregrine and raven and others which are suspected
of breeding such as the shag and fulmar.

The Kimmeridge clay cliffs are far less suitable for nesting birds
- rock pipit and carrion crow are the only regular
breeders. Lapwings occasionally breed in some clifftop fields
and oystercatchers on the more remote beaches.Buzzards
regularly patrol the area and breed in woods not far from the cliffs.

In autumn many migrants again visit the coast but
one of many features are the huge flocks of Swallows and Martins.
In addition, late autumn provides a time when species such as the Firecest
and Black Redstart may be seen and a gale in October may provide
a wind-blown Grey Phalarope.
In winter Peregrines, ravens and buzzards remain
in the area. Beaches will become home for a few rock pipits and redshank
and oystercatcher numbers sometimes top 60 at Kimmeridge Bay.
Offshore, especially near the bays, Slavonian
grebe and little gull may be seen and the winter usually provides
a record of a red-throated or Great Northern diver.
The coast of the reserve provides a wide variety of flowers and other
plants. Because the area of dry beach is generally small, plants commonly
found on beaches are restricted, but Sea Rocket and Sea kale
have been recorded.
Cliff plants are well represented and species such as thrift,
sea campion and rock samphire are widespread.
Specialities of the clay cliffs includeyellow-horned
poppy, cild Cabbage and grass vetchling, hairy buttercup,
hoary cress and henbane are local specialities of the main
car park at Kimmeridge Bay.
The flora of the chalk and limestone is fairly typical
of the wider Purbeck downs containing attractive plants such as bee
orchid, pyrimidal orchid, yellow wort, early gentian,
wild mignonette and common rockrose.
Other interesting plants to be found on or near
the cliffs include hound's tongue, wild madder and stinking
iris.
Whilst the clay cliffs west of Kimmeridge can be
rather dull for the botanist there are several unexpected species to be
found. The cliffs to the west of Kimmeridge Bay can prove very fruitful
and a number of rare and local species, in addition to those mentioned,
can be found.
The adder is the most commonly encountered
reptile, favouring the sunny slopes on the cliff tops and may occasionally
end up on the beach following small cliff falls.
Slow worms and common lizards are
present, though the former are not often seen. Grass snakes are
quite uncommon - you would be lucky to see one.
The diverse nature of this coastline provides an
ideal hunting ground for the naturalist at any time of the year with a
good chance of turning up the unusual or rare. Much is still unknown of
the wildlife in the area and there is considerable scope for further investigation.
