Local expertise has enabled a
plantation of almost 20 hectares of
conifers to be harvested and
extracted from one of Upper Lough
Erne’s historic islands without
disturbing the fragile eco-system on
it.The harvesting of the timber by the Forest Service is taking place
on Naan Island, close to Knockninny Quay.
The plantation of Sitka Spruce, probably the fastest growing
commercial conifer in Ireland was established on the island in
1970 and according to forestry officer, Noel Melanophy, is one of
the earliest maturing timber crops in the county, now being
felled after just 32 years growing!
This week, the contractor, Pat McManus, of PM Processing, from
nearby Macken was more than halfway through harvesting the
timber as he and his team of workmen kept an eye on the
weather. All his specialist machinery has to be ferried across to
Naan Island using specially adapted barges, supplied by
Michael McCaldin of Aghinver Boat Company. And when the
timber logs are cut to the right length on the island, they have to
be ferried across to a specially built temporary jetty at
Knockninny for loading on to lorries.
However the project is not new to Pat McManus, who has been
involved in timber harvesting contracts for many years. He
previously harvested conifers on the island in 1990 although
admits, the technology has advanced considerably in those 12
years with the expectant output having trebled. He has also
recently extracted timber from a number of islands in Co. Cavan,
including one on Garridice Lake.
He explained that previously he would have used 12 tonne track
excavators with specially fitted processing heads for felling the
trees but now uses more powerful machines of up to 24 tonnes.
The track machines are fitted with Lako harvesting heads and
with onboard computers in the cab and on the head which can
tell the operator the volume of wood, length of logs being cut and
their diameter. Using contract details directly from the mill, in this
case, Balcas, at St. Angelo, the operator will cut and pile the logs
according to their eventual use.
Pat says each of the Sitka Spruce trees harvested on Naan
Island, will be used for three different products processed at
three different mills owned by Balcas. The main butt of the tree
goes to the Enniskillen mill for structural timber, the middle
section to Magherafelt for palletwood and the smaller top part for
post material in Newtowngore.
Finnish technology is now at the forefront of the forestry
machines, with Pat McManus using the Lako harvesting heads
and Timberjack forwarder machines, the eight wheel transport
vehicles capable of carrying up to 20 tonnes of logs from the
forest to the shore for loading on to the barge. This brings the
logs across to the temporary jetty moored off Knockninny, which
are then piled ready for the Balcas lorries.
Each lorry can carry up to 25 tonnes of timber, and by the
beginning of this week, some 60 loads of timber were extracted
from the island.
At least six men are involved in the harvesting operation, two
harvester drivers, two men driving forwarders and two chainsaw
operators.
Mr. McManus says considerable planning was put in place to
make the harvesting operation as efficient as possible and to
minimise disruption to wildlife and flora on the island.
According to Mr. Noel Melanophy, the overall objective is to
maintain the integrity of the shoreline and not build any
permanent structures which might damage the environmental
aspects of the island.
Naan Island which extends to about 90 acres, is predominantly
used by the Forest Service and the remainder is in private
ownership.
Just recently, the Minister of Agriculture and Rural Development,
Brid Rodgers, announced proposals to create almost 20
hectares of new native woodland on the island, to replace the
conifer plantation now being felled.
Naan Island is recognised for its nature conservation interests
and the shoreline is covered by a number of desingiations such
as Area of Special Scieintific Interest, ‘Special Protection Area
and is also a candidate for a Special Area of Conservation.
The Forest Service now intends to expand the native woodland
habitat on the island to an area of some 36 hectares. The
woodland will be mainly by natural regeneration with the
woodland developed mostly from seed produced by existing
native trees on the island such as ash. Ground flora associated
with this type of woodland will spread gradually as the conditions
evolve. The resultant woodland will comprise of native species
such as ash, birch, alder, hazel and holly.
