This is a probability-based model that has been delivered as a DSS. It evaluates the wind hazard of a conifer stand plantation, based on some of the stand feature, like soil, cultivation, drainage, location, or metric measures (top height, average dbh) of the existing species. It provides information as the return period for that damage to occur, risk status and critical wind speed for both overturning and stem breakage risk. It allows to quantify the wind hazard existing in actual stands or, with the help of growth prediction models or yield tables, the future risk of wind damage assumed by current decisions on the establishment of new plantations, drainage improvements, thinning options, clear-cutting impact, rotation periods or the creation of retentions. ForestGALES can be used to calculate the risk for a particular stand in the single stand mode, or in the batch or multiple stand mode, for a number of stands one after another. Within these two modes there are three ways of making predictions: using field measurements, using stand characteristics provided by a yield model, or making predictions through time, calculating the risk of damage over a typical rotation from stand characteristics contained in yield models.
