Gone
with the Wind
Clearing up after Klaus
The severe storm that hit the coastal forests of south western
France and north western Spain in late January this year felled as
much as 70 per cent of the pine trees in parts of the coastal Aquitaine
region, south of Bordeaux. About 1 million hectares of Aquitaine forest,
which are predominately Pinus pinaster (Maritime pine), were affected
with 300,000 hectares ‘seriously hit’, and 60 to 70 per
cent of trees felled with ‘dramatic consequences’. In
total, in excess of at least 30 million cubic metres of timber in
the Aquitaine region has been affected by windblow.
95 per cent of this is privately owned. We have not heard as much
about this storm as we did 10 years ago, when many UK contractors
and hauliers took the opportunity to transport equipment to France
to assist with harvesting operations. Perhaps this is because the
French
timber industry has of course seen and had to deal with it all before,
and is simply going about the mass clear-up quietly and efficiently
this time around. However, due to the sheer scale of the damage and
the need to get log-sized timber cleared ahead of insect infestation,
we were invited down in to view the state of the woodlands and to
see if we could provide any assistance.
Such a colossal amount of timber to deal with, balanced against the
current global downturn affecting the markets, has led to most Frenchbased
timber companies concentrating initially on the establishment of ‘stackage’
storage areas, to hold the harvested timber. Each ‘stackage’
area is a major civil engineering project. Firstly the site is cleared
of windblown timber, then destumped and mulched. The high water table
in the region allows for the straightforward creation of high capacity
water lagoons running laterally down the site. The vast area in between
is then set out with a geometric system of roading and drains at 40m
intervals. The 1m ‘gap’ between stacks is filled with
a well organised irrigation network of pipes, sprayers and sprinklers.
These are fed by a large pumping/ recycling system flowing in and
out of the lagoons. In between the metalled roads, a movable ‘corduroy’
road, fabricated from sawn sleeper-sized timber, allows trucks to
haul timber and unload close to the stacks. A dual ‘in and out’
weighbridge installation completes a highly efficient facility capable
of holding in the region of
350,000 tonnes. One private forest management company alone was developing
six of these yards! If impressive empty, when seen even only part
filled with round timber, the stackage site is a surreal place, even
for the most hardened timber professional!
With the amount of ‘agency/ stakeholder liaison’ and paperwork
processing required in the UK to legitimately fell timber, I wonder
if and how we would react as an industry to constructing such storage
areas? Hopefully we won’t need to test this concern anytime
soon. With many stackage areas nearing completion, the industry in
the Aquitaine has turned its attention to ramping up the production
of harvesting the blown timber. Most of the badly affected area is
flat, similar in ground conditions to a large-scale Culbin, Tentsmuir
or Thetford FC forest! It therefore lends itself to a wide range of
harvesting equipment from small harvester/ tractor-trailer forwarder
combos to the purpose-built kit that we are used to.
The most common system deployed was a typically ‘European’
harvesting set-up of a larger harvester – JD1470 or equivalent
– and smaller forwarder such as the JD1110. Whilst seeming like
an unbalance, this made perfect sense of the combination of large,
rough mean trees, short flat extraction distances, small coupes (many
different forests and ownerships) and a
requirement to move between sites efficiently.
As ever in windblow situations, whilst some teams had mechanised solutions
(an excavator/felling head on site as well) many were still dependent
on motor-manual operatives
to ‘off root’ the stems – of course as close to
the blown stump as possible! Cut-to-length harvesting has never been
a more appropriate description for this type of work. The inherent
twisted nature of the Maritime pine leads to the requirement of a
multitude of very short lengths to be recovered to provide for an
economic breakout.
Depending on tree size, typically 3 different quality/diameter grades
of 2.65m logs, both 2.1m and 2.5m pallet and also 2.5m chipwood make
up the 6-grade cutting profile/ matrix in each stand. This calls for
precision cross-cutting and layout from the harvester operator and
a very skilled and patient forwarder driver. Whilst I am sure UK operators
could adapt, it was a far cry from green logs and pulp that we are
used to in the north of Scotland.
There were, however, already non-French national contractors working
in the Aquitaine, with
teams from Germany and Austria, as well as some of our more local
cousins from the Emerald Isle who were there with haulage capacity
as well as forest machines. The Austrian crew were working some conventional
machinery (harvester/ forwarder) but also a different machinery solution
in the form of a brand new Konrad mountaineering ‘Highlander’
harvester fitted with a clamping bench (clam bunk). This innovative
machine, with a 250hp Iveco engine as a powerplant, certainly seemed
well suited to working windblow. A fully rotating cab and Woody head
allowed for efficient handling and loading of the clam operations,
with all hydraulic pipework safely inside the 10m reach crane. The
4-wheel drive and crab steer configuration with patented step drive
(extending drive legs) pulled the load out to roadside where again
the Woody head proved to be an agile unit, this time processing.
We only saw this mountaineer working on flat ground, and I would question
its ability in softer conditions, but it would make an excellent addition
to a skyline set-up. If you’re more interested you can see them
(like everything else) on YouTube. In terms of timber haulage, as
well as local rigs there seemed to be a good number of European selfloading
trucks contracted, including a good number from Belgium, running both
artic and six and drag configurations. Some units were cross loaded,
the grip from the thick bark of the Maritime pine aiding load security.
Timber was flowing to local mills but also stackage yards for holding
and railheads for onward transportation. Whilst difficult to gauge,
I am sure most trucks were running on the optimistic side of weight
limits.
Optimism, in terms of a slowly improving Scottish domestic round timber
market(?) and several other factors, meant that we reached a decision
not to take on any contracts this time around ourselves. Whilst in
the end perhaps the logging rates didn’t impress, the scale,
planning and professional management of the clear-up operation certainly
did. Neil Stoddart
