Bark Thickness Equations for Mixed-Conifer Forest Type in Klamath and Sierra Nevada Mountains of California

Figure 4

Bark thickness model prediction errors according to tree size (DBH) for eight species within the mixed-conifer forests of California. Prediction errors calculated in percent terms for our California models, for FFE-FVS (Fire and Fuels Extension for the Forest Vegetation Simulator) [11, 12], and for the Larsen & Hann [13] bark thickness models for Oregon, where percent error is the difference between predicted BT and actual BT data calculated as 100 × (predicted-actual)/predicted.
