Relative Contributions of Forest Vegetation, Land Cover, Topography and Climate in Explaining Fire Regime Patterns (1974–2005) in Peninsular Spain

Figure 3

Correlation biplots based on RDA performed between the fire regime variables (response data set represented by black vectors) and the four groups of explanatory variables (red vectors with each group in a different colour) for the 15 territories analysed (see Table 2). Each vector points in the direction of maximum variation of the variable values. The length of the vectors indicates the correlation strength. Vectors pointing in the same direction indicate a correlation between them. Each biplot displays the best ranked and significant explanatory variables.
