CUMBRIA'S
AMPHIBIANS If
you like to breed in water but also need to keep your skin moist
when on land, what better place could you find to live than
Cumbria!! Not surprisingly, all six native species of amphibian
thrive in the county. The
Common Frog is widespread, even
near the tops of mountains at over 800 metres. Colour can be
variable from green to brown. Spawn (in the familiar large blobs)
is usually laid in late February or early March, perhaps later
in the colder fell tarns. Mating starts early - the photo below
was taken at Walna Scar in the Coniston Fells on 18th February.
Tadpoles are intitially black, like toad tadpoles, but become
brown speckled with gold as they grow. The
Common Toad is a little less hardy,
does not venture as high up the fells and prefers deeper water.
Its spawn is laid in strings two
or three weeks later than frog spawn. The Cumbria
has two of the largest colonies in England of the Natterjack
Toad at Drigg and Sandscale Haws - these form the subject
of a separate page ...see NATTERJACK
TOADS Newts
are possibly under-recorded in the county, as they generally
need some searching out. The Great-crested
Newt is a protected BAP Priority species that breeds
widely in the county. There are many breeding sites in the area
between Ambleside and Milnthorpe and along the length of the
Eden Valley, with more scattered places found on the north-west
coastal plain. Ideally they would like ponds without fish, but
increasingly seem to use garden ponds. Between April
and late June a search with a torch
at nighttime may yield a sighting - but REMEMBER it is
illegal to catch them or even disturb them. The
smaller (about half size) Palmate Newt
is possibly the most abundant in the county as it prefers acidic
water - there's plenty of that in the fells, but it is also
found in lowland ponds, even in gardens, where it likes newer
ponds with less well developed vegetation. The similar sized
(both about 10 cm long) Smooth Newt
is also common in the county, sometimes even in the same water
body as the other two newt species! The best distinguishing
feature is the spotted throat of the Smooth Newt - Palmate Newts
have a plain throat. In the breeding season male Smooth Newts
develop a crest but Palmate Newts do not - instead they have
characteristic black, webbed hind feet and a fine filament projecting
from the tip of the tail (these features show well in the photo
below of the male Palmate Newt (upper) but are absent in the
female Palmate (lower). Newts
lay their eggs singly on wrapped in vegetation. They hatch into
larvae known as efts ( below about 8 mm long)- efts acquire
their front legs first, unlike frog and toad tadpoles which
acquire their back legs first. I believe "eft" derives
from "ewt" the former name for a newt until "an
ewt" became the easier to say "a newt" (a similar
change happened in reverse when "a napron" became
"an apron")!
