| Abstract | The effects of fire on forest carbon and water cycling are not well understood, specially due to the difficulty of obtaining surface flux measurements in fire-affected areas with high temporal and spatial resolution. The present study aimed to characterize and analyse, using MODIS remote sensing data (MOD17 and MOD16 products), the temporal dynamics of gross primary productivity (GPP) and evapotranspiration (ET) in a primary Amazonian forest area affected by fire in September 2010 in the state of Para, Brazil. The forest area was mapped using a TM/Landsat 5 image acquired during the time of fire burning. The average values of GPP and ET for the 3 years pre-fire were 2487.8 g C m-2 yr-1 and 1410.2 mm yr-1, respectively. One year after the fire these values were ~6% and ~11% lower. The average values of GPP and ET 3 years post-fire were 2540.7 g C m-2 yr-1 and 1345.4 W m-2, respectively, showing that they were ~2% higher and ~5% lower than the average values verified prior to burning. Regarding these findings, it is important to note that GPP and ET values increased at an average annual rate of 17% and of 21%, respectively. We also found that after the fire GPP tended to be higher during the dry season (~5%) while ET tended to be lower (~8%). These patterns are related to changes in the photosynthetic capacity and light-use efficiency specially in the low canopy. We conclude that 3 years was enough time for this forest to recover its original state in terms of productivity and water loss. Despite this result, it is important to note that a high severity fire can alter the canopy characteristcs more strongly than a low severity fire, which means that distinct disturbance regimes will affect the carbon and water ciclyng after the fire in forested areas quite differently. | |||
