From: Revealing historical fire regimes of the Cumberland Plateau, USA, through remnant fire-scarred shortleaf pines (Pinus echinata Mill.)

Fig. 2

(A) A fire-scarred stump of a large remnant shortleaf pine (Pinus echinata) tree persists on the Cumberland Plateau, USA, and strongly contrasts with the current conditions of a closed-canopy forest, nearly devoid of living shortleaf pines. (B) Base of living shortleaf pine showing fire scarring on the bole and a partial cross-section with fire scars removed. (C) Shortleaf pine tree-rings and fire scars from the late 1600s to early 1900s. Calendar years of fire scars are provided within white arrows (inset shows entire sample). Samples were taken between 2017 and 2019 to reconstruct the characteristics of shortleaf pine historical fire regimes. Photographer: Michael Stambaugh
