Simulating dynamic fire regime and vegetation change in a warming Siberia

Fire Ecology

Table 3 Historic fire regime characteristics for the Taiga-tundra, Mid-taiga, and Southern taiga study landscapes. All characteristics except fire severity (see footnote) are calculated from the Global Fire Atlas (Andela et al. 2019) for the period 2003–2016

Landscape	Annual burned area (ha)	Av. number of fires per year	Av. fire size (ha)	Max. fire size (ha)	Fire rotation period (years)	Fire severity (dNBR)^a
Taiga-tundra	1101	2	236	32,134	908	0.1
Mid-taiga	7749	12	627	30,205	129	0.14
Southern taiga	16,232	61	265	14,920	61	0.02

^adNBR represents the spatial mean across each landscape from the gridded Fire Intensity and Burn Severity Metrics for Circumpolar Boreal Forests, 2001–2013 (Rogers et al. 2017) dataset. Minimum and maximum dNBR values across the circumpolar region recorded in this dataset are − 0.5 and 0.8, respectively, with higher dNBR values indicating higher burn severity (and hence, higher vegetation mortality)
