|Cors Caron - The
Tregaron Bog is
one of the few remaining examples of a raised peat bog in Britain.
Lying beside the river Teifi just above the small market town of
Tregaron on the edge of the Cambrian Mountains, there is now an
excellent walk through the heart of the Bog on a timber decked walkway.
The old railway track to the south of the
bog and alongside the road provides convenient access.
To the side of the track is a lake often
with a good selection of wildfowl
Entering the path through the timber arch,
one sees a number of small lakes
take the B4323 towards Pontrydfendigaid . At Maeslyn (see OS map) there
is a parking area and an entrance to the old railway line - now a track
extending the entire length of the bog adjacent to the road. Turning
right, you can head towards the observation tower, which offers bird
watching opportunities and fine views across the bog. Turning left,
follow the track past the lake on your right until you reach the Oak
archway at the entrance to the walkway. From here a circular boardwalk
takes you around the bog, returning to the railway track further to the
The Bog Asphodel
is the most colourful
of the peat bog.
The boardwalk takes
the walker through the centre of the bog and back to the old railway
foliose lichen common where little nitrogen is available in the soil.
A raised bog
such as Cors Caron was once the site of a shallow lake that became
filled with vegetation. Its acidic nature was ideal for the various
species of Sphagnum moss which not only increase the acidity of the
water, but which are very absorbent and help to hold the water in the
bog and prevent excessive evaporation. The acid also prevents
decomposition, so layer upon layer of Sphagnum gradually builds up - in
this case over some 12,000 years to produce a shallow dome
characteristic of the raised bog.
The acidic and
nutrient deficient conditions are suitable for a unique flora with
plants like the Purple Moor Grass dominating the landscape. In places
can also be seen the Cotton Grass, the Bog Asphodel and the carnivorous
The Sundew is an
insectivorous plant growing in wet peaty areas.
Cors Caron is an important breeding
site for the Otter Lutra lutra
The Red Kite is commonly seen over
Cors Caron and the surrounding hills
holds that if cattle ate the Bog Asphodel, their bones would become
brittle. This is because the Asphodel grows on land lacking in
nutrients such as calcium that are required for strong bones. This is
reflected in the plant's scientific name Narthecium
The Sundew gets
its nitrogen from insects that it traps on sticky hairs on its highly
profusely in many areas of the bog is the lichen Cladonia. Lichens are
unique as they are composed of a relationship between an alga embedded
within the tissues of a fungus. The Cladonia lichen is closely related
to the Reindeer 'Moss'- an important component of the diet of the
reindeer in northern Europe.
