Table 1. Location and treatments for plots sampled for this study.

Table 2. Community level, functional type level, and key shrub species mean ± SE for biomass and C and N.

Figure 2. (a) Absolute and (b) mean relative within-treatment C stocks (or biomass) for each functional type and (c) absolute and (d) mean relative within-treatment N stocks. Points overlaid on box plots in (a) and (c) indicate the total C or N stock for a functional type in a single replicate plot. Box plot boundaries denote quartiles and medians, and whiskers denote 1.5 * interquartile range. The corresponding significance of differences between burn treatments can be found in .

Figure 3. Carbon and N stocks and C:N of leaves (circle), stems (triangle), and whole plants (square) for four shrubs. Each row corresponds to the species denoted in the N stock column. Arithmetic mean and standard error are reported for C and N stocks, and geometric mean and standard deviation are reported for C:N.
