Pentre Ifan, near Brynberian in north
Pembrokeshire, is famous for its cromlech, one of the best examples
of its kind in Wales. The ancient woodland nearby which is Tycanol
NNR represents the type of forest that surrounded Pentre Ifan when
that tomb was built.
The NNR includes both woodland and boulder-strewn heathland with
rock outcrops. One of its outstanding features is the richness of
the lichen flora growing on the trees and rocks.
The management of the reserve aims to maintain the ancient woodland
and the lichen populations. This management includes the use of
sheep, cattle and ponies to graze both heathland and woodland.
Grazing controls the growth of ground vegetation which might
otherwise shade the boulders and lower trunks of trees where some
of the important lichens are found.
Apart from the Pentre Ifan cromlech, there are numerous
archaeological sites in the area, including an iron age fort within
the NNR. These and the nature of the ancient woodland contribute to
an atmosphere of great antiquity and a long association with
man.
CCW manages the reserve in partnership with the Pembrokeshire
Coast National Park.

Wildlife
The northern and lowest part of the reserve, known as Hagr y
Coed, is wet woodland, with numerous small spring-fed streams. Oak
dominates the canopy which also contains ash and downy birch. There
is an understorey of scattered hazel, rowan and holly.
Hagr y Coed also contains a number of long abandoned fields. The
drier fields contain acidic grassland with invading bracken and
gorse but the wetter areas are developing secondary woodland of
mainly sallow, birch and alder.
Between Hagr y Coed and the open heathland of Carnedd Meibion
Owen in the south, lies the steeply sloping Tycanol Wood. This is a
typical Welsh upland oak wood, where sessile oak is the dominant
tree with scattered birch, mountain ash and hazel. All of the
woodland has a long history of agricultural grazing – grazed
woodland of this type is known as ‘wood pasture’.

The wealth of rock exposures in the form of tors, low cliffs,
crags and boulders, provide a wide variety of habitats for plants
and animals.
A walk through the woodland and the heathland will reveal that
many of the surfaces of the rock faces, tree trunks and branches
are covered in lichens. Nearly 400 different species have been
identified, including many rarities, making Tycanol one of the most
important sites for lichens in Britain.
Growing in the shaded and damper hollows of the tors and cliffs
are a number of nationally rare fern species. These include wilsons
and tunbridge filmy ferns and hay-scented buckler fern. These
locations also support a wide range of mosses.
Other features of interest include:
- A population of dormice.
- Polecats.
- A wide variety of insects.
- Some of the typical birds of west Wales including raven,
buzzard, pied flycatcher and redstart.
