Table 3 Mann-Kendall test (S) and standardized test statistic (Z) results for burned area (B_A) and number of fires (N_F) data collected between 2001 and 2021 in two of Ghana’s ecological zones (Guinea-savanna, GSZ; Forest-savanna mosaic, FSZ) during research to characterize the fire regime of the area using a remote sensing approach. Kendall rank coefficient (Tau), probability value (P), and trend direction (at 95%) are also given. No trend was found to be significant (P > 0.5)
