Round the reserves
Month by month, what to look out for...
January
Look closely at those winter flocks of small birds as the weather
gets a little colder. Blue, great, long tailed tits and goldcrests
will mix together in loose flocks as they roam around searching
for food to eat. Whether at Burledge Hill or on Hellenge Hill these
flocks will often contain more uncommon species such as firecrest
or even the continental form of coal tit, distinguisged from its
UK cousin by its slate grey body plumage. A lucky visitor to Folly
Farm may encounter a roosting woodcock as they hide in the grassland
waiting for night to return when they’ll feed in the wet grass.
These unusual waders rely on their complex plumage of blacks and
browns to conceal them from any unsuspecting predator.
February
Down on the coast the bleak openness of the Severn Estuary can be
quite daunting. However, on a late afternoon the thrill of seeing
a short-eared owl quartering the saltmarsh at Walborough or at Blake’s
Pool will make the day worthwhile. Flocks of meadow pipit can be
encountered as they move in and out with the tide and at Clapton
Moor these birds can be seen alongside stonechats as they feed on
invertebrates in the grass.
March
The first signs of spring, and warblers such as blackcaps and chiffchaffs
will be beginning to sing. At Weston Big Wood these birds will sing
from the sides of the ride as brimstone butterflies drift along
in the warming sun. At Pill Paddock or Brandon Hill the pond will
be full of frogs and maybe even toads as the frost free nights encourage
them to breed. Common buzzards can also be seen circling over our
woodland sites and at Dolebury Warren they seem to circle out of
sight as spring thermals take them higher and higher into the air.
Reserves update
Along the rhyne sides at Lawrence Weston Moor
water voles will be active, seeking out mates and searching for
safe areas to have their litters. The warming temperature and longer
daylight will draw dormice out of their dormancy and at Goblin Combe
and Tickenham Ridge these small mammals will begin the year in search
of food. At Willsbridge Valley dippers will be returning to breed
along the Siston Brook, oblivious to the throngs of children going
about the educational activities that make this reserve a very special
place.
Working wonders this winter
The onset of winter marks the start of a busy season for us, especially
in woodlands. As nature slows down and wildlife hides away, work
can be done that would cause too much disruption during the main
growth seasons of spring and summer. At that time of year tree felling
can be disastrous for nesting birds, and also for woodland ground
flora. Bluebells and wood anemone burst into life for a short period
early in the spring and carpet the woodland floor before the trees
sprout leaves and shut out the light. Obviously we want to avoid
disruption at these sensitive times. However during the winter what
initially can look like quite drastic measures in our woodlands
will, in the spring, benefit many of these species we seek to protect.
At Weston Big Wood we’ve been doing just this by establishing
our second coppiced coupe. This means that we’ve cut down
all the trees in a small area of under a half acre. Initially this
will let in lots of light so that during the spring there’ll
be an explosion of woodland ground flora. Plants or seeds that have
lain dormant for years will take this rare opportunity to flower
and set seed. In subsequent years this little area will go through
different stages, young shoots will grow from the cut stumps and
bramble will start to move in. Eventually the shoots will grow taller
and create a shrubby layer that will shade out the bramble. Each
of these stages creates a unique set of conditions that will benefit
different species.
The aim at Weston Big Wood is to establish a “coppice rotation”.
This is a number of coupes, all next to each other, of which only
the most mature would be cut down or “coppiced”. This
means that the full range of coppice habitats will be present at
any one time, from the recently coppiced open ground rich with wildflowers
to the mature coppice that can be a home to dormice.
All this tree felling certainly produces a lot of wood, which is
the reason that coppicing used to be so widespread in England. Not
so long ago, a regular and reliable crop of timber was essential
as a source of fuel, either as firewood or as charcoal. The mature
coppice coupes provided this. Every year there would be a crop of
conveniently sized timber, easily cut down and removed. On top of
this it was all from a sustainable source, and coppicing in fact
actually prolongs the life of the individual tree.
We plan to produce some charcoal from this coppice which people
can use next summer. If demand is good then we would like to produce
enough each year to support the cost of doing the coppicing. Look

How to get there
From B3124 Clevedon-Portishead road, turn
into Valley Road. Park in the lay-by approx 300 yards on right,
and walk up the hill. Steps lead into the wood from the road.
Grid ref: 456 750
Access Paths can be muddy, slippery and steep-sided. Keep well away
from the quarry sides.
