The 55 JFSP plots were established to capture forest types, fire histories, and severity levels beyond those found within the YFPD. The plots were square 50 m × 50 m plots established in Pinus ponderosa, Pinus jeffreyi, and Abies concolor – Pinus lambertiana forest types between 1,431 m and 2,250 m elevation. Plots were installed post-fire based on a randomly chosen locations stratified by burn severity levels as calculated from the differenced Normalized Burn Ratio (dNBR). For details on site selection see Furniss et al. (in review). In the field, plots were located using a handheld GPS and then a more precise position was collected using a survey-grade GNSS receiver. Within each plot, all trees ≥10 cm DBH were identified, measured, and mapped. Tree measurements included DBH (1.37 m), species, vigor, and lean (distance and direction). Trees were mapped according to the methods in Lutz et al. (2012).
