  1. Example for How Risk is Calculated for a Pixel Maximum Mortality for Model = 70% Model Criterion Weight Distance from Pest Range 0.5 Host Basal Area 0.3 Host QMD (Avg DBH) 0.2 Risk 10 0 Risk 10 0 Risk 10 0 8 6 4 Host Basal Area Distance from Pest Host QMD Total Risk = (0.5 x 4) + (0.3 x 6) + (0.2 x 8) = 2.0 + 1.8 + 1.6 = 5.4 = 5 % Host Loss = Total Risk/10 x Maximum Mortality for Model = 5/10 x 70% = 35% % Total Forest Loss = % Host Loss x Host BA/Total Forest BA
