In the UK we experience the occasional severe storm which causes
catastrophic windthrow but I am not aware of any predictive studies into
More of a problem for us is what we call endemic windthrow which occurs as
trees reach a certain height and gradually creeps through the forest until
eventually a large proportion of the trees are blown (50 to 100%). Most of
our forests are planted and this problem is partly related to that.
UK Forestry Commission has developed a predictive model based on four
factors namely; Altitude, Soil Type, General Windiness (related to location
within UK), and topex (a measure of the degree of topographic shelter.
