4.5.3 Spatial clustering of the vulnerability of grid cells across the protected area Spatial autocorrelation analysis (Global Moran's I) of grid-cell vulnerability index values showed highly significant (z-score >19.62, p < 0.001) positive spatial correlations (I = 0.68) across the HFPA, meaning that neighboring grid cells exhibit similar vulnerability index values more often than expected by chance.
