Fire scar history diagrams for the four study sites (left side); Olga Lake (OLG), Wolf Lake (WFL), West Udell Hills (WUH), and Shelly Lake (SHL). Fire scar history diagram on right shows all samples and fires for all sites combined (ALL). On all diagrams, horizontal lines represent the period of tree-ring record for trees. Vertical ticks on horizontal lines indicate fire scars. On the left ends of horizontal lines, slanted and vertical lines indicate inner-most ring and pith years, respectively. On the right side of horizontal lines, slanted or vertical lines indicate outermost ring or bark year, respectively. At the bottom of each diagram is a composite record of all fire event years. Years are colored by seasonality where: yellow = earlywood, orange = latewood, blue = dormant, and no color = undetermined seasonality
