摘要

Clear cutting has been the traditional silvicultural practice for most of eastern Canadianforests for many decades. However, more recently there has been a shift towards partialcutting regimes, in which individual trees are left standing mainly to improve the eco-logical value of the site and speed up the process of natural regeneration. Due to de-creased stand density and the creation of gaps those stands are probably more vulner-able to wind damage than those managed with a traditional approach, which mightcounterbalance any beneficial aspects. A quantification of the wind risk of an area is desirable to support decision processes indesigning cutting plans. Here we present the results from a spatial modelling approach.The model design as well as the sensitivity of its modules are discussed. A major factorfor uncertainty is the coarse resolution of the stand data information. A better modelperformance could be achieved using more data sources like remote sensing.
