Leaf area index (L*) and above-ground biomass were determined by destructive sampling for a 400m2 area of terra firme Amazonian rain forest and for an adjacent clearing. While L* in the forest varied considerably with height though the canopy for four separately sampled 100m2 subplots, the cumulative L* was similar with a mean value of 5.7 + ou - 0.5. The total above-ground dry biomass of the forest was 265 + ou - 95t ha-1, while the leaf dry biomass was 6.3 + ou - 0.5t ha-1. The specific leaf area (SLA, cm2g-1) was determined, and found to vary linearlywith canopy depth rising from 65cm2g-1 at the canopy top, to 114cm2g-1at 5m above the forest floor. The average for the four subplots was 90cm2g-1. The leaf area index of grass in the clearing (blade only) averaged 0.8 + ou - 0.4, and total green area index (blade + stem) averaged 1.2 + ou - 0.6. Total above-ground dry biomass (blade, stem) was 2.3 + ou - 0.6t ha-1, while including dead plant material gave a total dry biomass of 5.6 + ou - 2.1t ha-1. Specific leaf area of the grass was 79cm2g-1. The results clearly demonstrate the profound change in leaf area and biomass which accompany Amazonian deforestation. |
