FORRISK Seminar : Wind damage risk to forest

The seminar took place on Wednesday 29th October 2014 at the Bizkaia Aretoa of the University of the Basque Country, Bilbao.

This FORRISK seminar was organised by NEIKER and the Regional Government of Bizkaia, in collaboration with EFIATLANTIC and Hazi, with the participation of researchers from FORRISK partner, INRA

The seminar illustrated how forest storm damage risk can be calculated for a region using a mechanistic risk model that was originally developed in the United Kingdom.

We demonstrated how the model has been adapted for the Spanish Basque Country and in particular for radiata pine and eucalyptus.

We also demonstrated how the model is being validated by comparison with actual wind damage from Storms Klaus and Xynthia and how the model can be used to calculate the risk to forests at a regional scale using remote sensing data (e.g., aircraft LiDAR) as model input.

After the talks the participants visited an experimental site to see tree pulling, which is essential for obtaining good model parameters for rooting resistance relevant to local site conditions.
