Figure 2

Master fire chronology for the Rincon Peak study area in southeastern Arizona. Horizontal lines represent the composite fire chronology for multiple fire-scarred trees collected over each 2 ha plot (range = 2 to 12 trees). Solid horizontal lines represent recording (i.e., at least one tree was susceptible to fire-scar) and dashed horizontal lines represent non-recording periods (i.e., no trees were susceptible to fire-scar). Small vertical dashes represent fire events in a particular year. Plot numbers on the right correspond to geographic locations (Figure 1), arranged form north (top) to south (bottom). Years labeled along the bottom correspond to landscape fire years (i.e., years when two or more plots were fire-scarred).
