about the concerted action
efficient and safe harvesting and log conservation methods
European countries were affected by the storms in December 1999. Forests
were strongly damaged in Denmark, Sweden, France, Germany, Austria and
Switzerland and the wind-fallen trees represented in some regions several
times the average annual harvested volume.
damages were estimated in Europe at the never seen level of about 180
million m3 to be compared to the 250 million m3 harvested each year in
the European Union.
economic and ecological reasons like the prevention of phytosanitary risks
and fire, it is very important to harvest without delay the wind-fallen
or broken trees. This is also the only way to save the quality of that
wood from degradation and to keep it in good conservation conditions for
the wood industry supply during the coming years.
these harvesting and logging operations must be conducted in a very short
time (before the hot season : spring and summer) so even the non directly
affected European countries has contributed by sending professional manpower
and equipment. They could also participate by their former experience of log
conservation methods which includes the effects on wood quality for timber
or paper use.
fact, this situation gave us the opportunity to a lot of local experiments
on safe and efficient harvesting methods, respectful of the environment,
in storm damaged forests, and on new log conservation methods concerning
a great number of different species and conditions in Europe.
learnt from the statistics, such storms will occur at a lower level more or
less every five to ten years somewhere in Europe. It is important to take
benefit of all the experiments that will be conducted on harvesting and log
conservation in storm damaged forests to be ready to react more quickly when
a new storm will occur.
a concerted action appeared to be the appropriate frame for building a
European network that has gathered and summarised the different experiments
and their results (successful or not) in a practical technical guide for
forest- and wood industry managers.
allows for learning from these results and sharing of knowledge between
the different European countries so that time, money and lives can be
saved for the next time.
main objective of this project is to contribute to answer the first two
questions adressed to foresters and wood industry managers facing storm
to harvest the wind fallen or broken trees in safe economic and ecological
ways, to prevent fungus or insect diseases and fire risks and allow for forest
How to keep the wood quality
to save the wood industry supply and the foresters' incomes through efficient
log storage and conservation methods?
objective has been achieved by the following actions:
Producing, via the exploitation of all relevant publications, patents or industrial
experiences, a survey of the practical available methods and their conditions
Identifying the main unsolved questions.
a list and following up the ongoing experiments in the different European
countries affected by the December 1999 storms.
additional experiments to cover as many species and conditions as possible.
harmonised procedures for homogeneous presentation of the results, to allow
the comparison and valuation of the different methods; for harvesting, the
harmonised procedure produced by the European concerted action AIR3.CT94.2097
(CA) will be used, with additions for damage description. This harmonised
procedure will ensure that the results cover all the technical, economic,
ecological and security aspects.
a practical technical guide brought up-to-date from the initial survey with
the followed-up and validated experiment results.
to the dissemination of the up-to-date available efficient and safe methods
via this website, through a final technical seminar for both forest- and industrial
users, scientists and forest services/administration, and the diffusion of
the technical guide by each partner in its own country.
