Extended Data Fig. 4: Scatterplots of field-measured shrub and graminoid cover and NDVImax by years since fire based on Landsat imagery on GEE.
From: Regional fire–greening positive feedback loops in Alaskan Arctic tundra
a–l, Panels correspond to tundra subregions North Slope (a–c), Noatak (d–f), Seward (g–i), and Southwest (j–l). m–o, Panels correspond to all of the Alaskan tundra. Symbols ‘*’ and ‘**’ after the correlation (R) values correspond to p < 0.01 and 0.001, respectively. Field data were from AKVEG. DS: deciduous shrub; ES: evergreen shrub; GD: graminoid.
