Fig. 1. Global distributions of the static forest fragmentation index (FFI) and the dynamic FFI (ΔFFI) for global forest landscapes.

Fig. 1

a Static FFI in 2000, (b) static FFI in 2020, (c) ΔFFI from 2000 to 2020; and comparisons of (d) FFI values for 2000 and 2020, and (e) ΔFFI values across climatic zones. d, e The bar heights showed mean value, and error bars showed one standard deviation. The significance of the differences in static FFIs and ΔFFI among climatic zones was tested using the two-side Tukey-HSD test, which adjusted for multiple comparisons, and letters in each bar showed post-hoc differences in mean static FFIs and ΔFFI with P < 0.001. d The numbers of forest pixels (n) from tropical to boreal zones are 581,649, 381,768, 1,031,907, and 1,384,718 in 2000, and 569,260, 378,518, 1,055,401, and 1,385,159 in 2020, respectively. e The numbers of forest pixels (n) from tropical to boreal zones are 553,655, 363,858, 1,021,172, and 1,320,564, respectively.
