From: Impacts of a single fire event on large, old trees in a grass-invaded arid river system
Fire impact to trees at six sites along Ormiston Creek relative to Δ NBR calculated from Sentinel 2 imagery. Data were categorised according to equal intervals (low = 51–137, medium = 138–225, high = 226–312, extreme = 313–400) with darker colours indicating higher severity fire. Values below 50 were not displayed as examination of unburnt areas across the entire Sentinel image indicated this was the threhold above which change due to fire (as opposed to variation not related to fire) was observed. Inset shows entire fire scar relative to the study sites
