Testing Vegetation Flammability: The Problem of Extremely Low Ignition Frequency and Overall Flammability Score

Figure 3

Hierarchical cluster analysis based on standardized measured flammability parameters: ignition delay (ID), ignition temperature (IT), flame extinguish time (FET), and maximal temperature (MT). Distances presented in the dendrogram are automatically rescaled by the SPSS software and thus the presented scale does not show the calculated distances.
