Storms regularly damage European forests. In December 1999, forests were badly affected in Denmark, Sweden, France, Germany, Austria and Switzerland, and the wind-fallen trees represent, in some regions, several times the average annual harvested volume. This damage was estimated to have reached the, as then, unseen level of about 180 million m≥, compared to the 250 million m≥ harvested each year in the European Union. This large area of damage has made a huge experimental field where methods for efficient and safe harvesting and log conservation could be improved. For economic and ecological reasons, like the prevention of phytosanitary risks and fire, it is very important to harvest the wind-fallen or broken trees as soon as possible. Harvesting 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. The statistics show such storms occur at a lower level more or less every five or ten years anywhere in Europe. A concerted action appears to be the appropriate frame for building a European network that will gather and summarise the different experiments and their results in a practical technical guide for forest and wood industry managers.
The main objective of this project is to answer the two questions addressed to foresters and wood industry managers facing storm-damaged forest:
1) How are the wind fallen or broken trees to be harvested in safe economic and ecological ways, to prevent fungus or insect diseases and fire risks, and allow for forest restoration?
2) How is the wood quality to be maintained, and the wood industry supply and foresters incomes saved through efficient log storage and conservation methods?
This objective will be achieved by:
1) producing, via the exploitation of all relevant publications, patents or industrial experiences, a survey of the practical available methods and their conditions of use
2) identifying the main unsolved questions
3) following up the ongoing experiments in the different European countries affected by the December 1999 storm
4) suggesting additional experiments to cover as many species and conditions as possible
5) building harmonised procedures for a homogeneous presentation of the results, to allow the comparison and valuation of the different methods. This harmonised procedure will ensure that the results cover all the technical, economic, ecological and security aspects
6) writing a practical technical guide, brought up-to-date from the initial survey, with the validated experiment results
7) contributing to the dissemination with the latest efficient and safe methods, and developing a specific website dedicated to the project and a final technical seminar for both forest and industrial users, scientists and forest services/administration. Partners will distribute the technical guide in their own countries.
Progress to Date
1) The validated harmonised procedures for log conservation will be finished in 2003.
2) The report about the remaining unsolved problems will be finished in 2003.
3) The report about the relevant additional experiment will be finished in 2003.
4) The thematic structures for the final technical guide concerning the harvesting and conservation topics are agreed. The redaction will occur during the first semester of 2004.
5) The draft of a terminology/glossary are under discussion to facilitate mutual understanding.
6) The preparations for the final seminar in Germany have been started.
This project has achieved its objectives 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 of use.
Identifying the main unsolved questions.
Making a list and following up the ongoing experiments in the different European countries affected by the December 1999 storms.
Suggesting additional experiments to cover as many species and conditions as possible.
Building 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.
Writing a practical technical guide brought up-to-date from the initial survey with the followed-up and validated experiment results.
Contributing 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.
