Appendix A. Maps (Fig. A1) of south Florida, the lower Florida Keys, and Big Pine Key and tables showing (Table A1) Chamaecrista keyensis census regime at each experimental plot and (Table A2) a summary of data structure for Chamaecrista keyensis fire experiment data structure.

 
   FIG. A1. Maps of the fire season and Chamaecrista keyensis study site. (a) South Florida outline. Oval indicates the lower Florida Keys. (b) Vegetation types of the lower Florida Keys. Oval indicates Big Pine Key. (c) Big Pine Key vegetation map showing fire treatment plots, indicated by groups of square (3 for each of 4 experimental blocks). The three squares within each group represent 3 macro-plots: control, summer burn, and winter burn. The term "open" indicates open pineland, and "shrubby" indicates shrubby pineland.

   Notes: TSF is time since fire (years) at the first census. Density is based on counts in stratified random census plots at first census only.

† Winter burn in this block was delayed one year.

‡ Winter burn in this block was cancelled.

§ Number of plants censused were cumulative over four censuses (1998–2001).
