Fire intensity

Collect and qualify melting of tags on rebar and trees;

Perform melting experiments to qualify fire temperatures;

Aluminum tags

Map projected temperatures across plots;

Compare average temperatures with BAER projections;

Compare consumption, tree damage, and tag data;

Analyses

Map infrared changes during the fire;

Calculate calorie consumption (∆biomass by layer);

Calculate average tree damage;

Other measures of intensity

Rationale: Fire intensity has a large effect on nutrient losses: N volatilizes above 200 °C, S above 375 °C,

and P and K above 774 °C (DeBano et al. 1998). Nutrient losses are thought to affect long-term tree growth

(Busse et al. 1996). Many aluminum tags were completely melted on our grid systems (fig. 4); because Al melts

above 660 °C (Lide 2002), the potential for major nutrient loss seems high.
