Figure 2. A conceptual model showing the different stages of vegetation, soil, and carbon flux components across mature forest and a spectrum of burn frequencies. Intact = flux chambers over unaltered subplot locations, Trenched = subplot locations trenched to sever roots and denuded of vascular vegetation. Dark = flux components of chambers covered to exclude insolation, Sun = uncovered chambers. RSGV = respiration of soil and all ground-level vegetation, RHNV = heterotrophic respiration and non-vascular vegetation; NEEGS = net ecosystem exchange of C from the ground surface; GPPGV = gross primary production of all ground-level vegetation, GPPNV = gross primary production of non-vascular vegetation.
