Innovative direct seed methods of cherry and oak - in the framework of the COST Action 42 "Growing Valuable Broadleaved Tree Species ValBro", in which 26 nations are involved

Economically viable forest management must find new ways to reduce costs for artificial regeneration of old tree stands. Direct seed has great rationalisation potential and can contribute to safeguard valuable broadleaved tree species.

Contexte initial

Cherry is one of the best paid timber in Europe, but its planting needs high investments. The innovative direct seed methods developed and tested at SHL offer a rational way to initiate cherry regeneration within an extremely short time. To avoid high investments in machines, common agricultural equipment is remodelled and tested for direct seed in the forests. The method is then refined and extended to trials with oak seeds, which may be much more difficult in handling.

But

Development of mechanical seed methods, which make the preparation of the terrain superfluous. Some positive side effects are: decreasing damage caused by game animals, an improved rootsystem and a better choice of high quality timber.

Compétences clés

Rational methods for regeneration of forests during normal operations and after storms, due to harvest caused by outside factors and in the light of climate change.

Résultat

The first trials were realised efficently and successfully. A new seed with germinable cherry will be now carried out and a new trial series with acorns is prepared and carried out.

Perspectives

Once the trials are successfully completed, recommendations for the silvicultural practice will be elaborated. These will be widely communicated, by means of publications and events on the basis of demonstration plots.
