Fig. 2: Comparison of the distributions of fire occurrence in the historical (pre-1880) and the contemporary (1984–2022) periods for all North American tree-ring fire-scar network (NAFSN) sites in the United States and Canada.

From: A fire deficit persists across diverse North American forests despite recent increases in area burned

Fig. 2

Analyses show the percent of NAFSN sites burned (a) and the average percent of sites burned within hexels (b) (see Fig. 1 for hexel map). For reference, 6% of NAFSN sites burned, on average, in the historical period (a; Table 2) and an average of 7% of sites burned, among hexels, in the historical period (b).
