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.
