Distribution of site-level values (n = 39) of the proportion of fire scars present in earlywood relative to latewood from seven studies on ponderosa pine (Pinus ponderosa) in Colorado, USA, used in the fire regime meta-analysis of 2017. The dashed black line at value 1.0 marks the point at which observations are equal between seasons; to the left of the line are observations with a majority of latewood fire scars, and to the right of the line are observations with a majority of earlywood fire scars
