Ashwell Quarry is a fine example of how
old chalk pits can develop into chalk grassland. The reserve stands as a
sheltered oasis for wildlife in an otherwise agricultural landscape. Ashwell
Quarry Springs are a minor source of the River Cam and have their own special
wildlife interest.
The quarry is very old and we know that in more
recent times parts were cultivated and grazed. After quarrying finished about
one hundred years ago, it slowly developed
scrub and
much of the open grazed grassland - rich in plants - was lost.
In summer the reserve is full of plants such
as pyramidal orchid, field and small scabious, clustered bellflower and glaucous
sedge. Deep shaded hollows add their own intererst and many of the older
thorn and elder bushes support rare mosses.
The adjacent Quarry Springs produce a stream
of water at consistent temperature of about ten degrees centigrade, which
is the very special requirement of some of the rare species of flatworm which
thrive here. |
