In France, storm Martin storm of 1999 severely affected forests and plantations in the Aquitaine region, with estimated timber losses of 26.1 million m3, most of which were in Maritime pine (Pinus pinaster Ait) stands. It has been estimated that storm Klaus, which hit northern Iberia and southern France in January 2009, was responsible for French losses between 1.34 and 1.77 billion Euros for its effect on Maritime pine plantations alone. This figure comprises losses in market value, future value, reforestation costs, and indirect damage to the affected stands. Despite the recorded maximum wind speeds from Klaus not differing greatly between Portugal, Spain, and France, wind damage to the extensive areas of plantations of Eucalyptus spp. in the Iberian peninsula were not reported, suggesting negligible losses. Foresters could benefit from information on the relative risk and economic benefits of these 2 species and the impact of their management choices under a changing climate in which extreme winds are predicted to become more common in the Bay of Biscay. We therefore tested the wind risk to eucalyptus and pine with differing rotation lengths using the wind risk model, ForestGALES. We also looked at the impact of these management choices on their overall economic performance accounting for all input costs (e.g. planting costs, site preapration, thinning and harvesting costs, etc.) and the value of thinnings and the final crop, together with their overall carbon storage potential. We found that eucalyptus could provide a potential alternative to pine for reducing the impact of wind damage due to its faster growth and shortened rotation periods.< Leer menos
