Wall Fork fire history chart (a) and age structure for trees ≥ 10 cm DBH, including fire-scarred pine trees (b). In a, each horizontal line represents one tree, while the site composite timeline highlights years when at least two trees recorded a fire scar. The cause of a corresponding fire occurrence in the West Virginia Division of Forestry’s unpublished spatial database (1987–2020) is indicated. In b, tree species in the intermediate fire tolerance group include blackgum (Nyssa sylvatica; n = 5) and sassafras (Sassafras albidum; n = 2), while mesophytes include red maple (Acer rubrum; n = 14) and sourwood (Oxydendrum arboreum; n = 5)
