Description: A survey of a 18 ha plot (300 m N-S, 600 m E-W) east (upwind) of the eddy flux tower at km 83, Tapajos National Forest, Para, Brazil was done in March 2000. Diameters of all trees > 35 cm dbh were recorded and on three transects diameters of trees between 10 and 35 cm dbh were recorded. These data are compared to independent biomass surveys done previously in the same forest in 1984 and 2000. These data were used to calculate net ecosystem productivity (NEP) and the role of this forest as a carbon source or sink.

Publication_Abstract: We used two independent approaches, biometry and micrometeorology, to determine the net ecosystem production (NEP) of an old growth forest in Para, Brazil. Biometric inventories indicated that the forest was either a source or, at most, a modest sink of carbon from 1984 to 2000 (+0.8 +/- 2 Mg C(.)ha(-1.)yr(-1); a positive flux indicates carbon loss by the forest, a negative flux indicates carbon gain). Eddy covariance measurements of CO2 exchange were made from July 2000 to July 2001 using both open- and closed-path gas analyzers. The annual eddy covariance flux-calculated without correcting for the underestimation of flux on calm nights indicated that the forest was a large carbon sink (-3.9 Mg C.ha(-1.)yr(-1)). This annual uptake is comparable to past reports from other Amazonian forests, which also were calculated without correcting for calm nights. The magnitude of the annual integral was relatively insensitive to the selection of open- versus closed-path gas analyzer, averaging time, detrending, and high-frequency correction. In contrast, the magnitude of the annual integral was highly sensitive to the treatment of calm nights, changing by over 4 Mg C(.)ha(-1.)yr(-1) when a filter was used to replace the net ecosystem exchange (NEE) during nocturnal periods with u* < 0.2 m/s. Analyses of the relationship between nocturnal NEE and u* confirmed that the annual sum needs to be corrected for the effect of calm nights, which resulted in our best estimate of the annual flux (+0.4 Mg C(.)ha(-1.)yr(-1)). The observed sensitivity of the annual sum to the u* filter is far greater than has been previously reported for temperate and boreal forests. The annual carbon balance determined by eddy covariance is therefore less certain for tropical than temperate forests. Nonetheless, the biometric and micrometeorological measurements in tandem provide strong evidence that the forest was not a strong, persistent carbon sink during the study interval.

Publication_Abstract: We combined measurements of tree growth and carbon dioxide exchange to investigate the effects of selective logging on the Above-Ground Live Biomass (AGLB) of a tropical rainforest in the Amazon. Most of the measurements began at least 10 months before logging and continued at least 36 months after logging. The logging removed ~15% of the trees with Diameter at Breast Height (DBH) greater than 35 cm, which resulted in an instantaneous 10% reduction in AGLB. Both wood production and mortality increased following logging, while Gross Primary Production (GPP) was unchanged. The ratio of wood production to GPP (the wood Carbon Use Efficiency or wood CUE) more than doubled following logging. Small trees (10 cm<DBH<35 cm) accounted for most of the enhanced wood production. Medium trees (35 cm<DBH<55 cm) that were within 30 m of canopy gaps created by the logging also showed increased growth. The patterns of enhanced growth are most consistent with logging-induced increases in light availability. The AGLB continued to decline over the study, as mortality outpaced wood production. Wood CUE and mortality remained elevated throughout the three years of post-logging measurements. The future trajectory of AGLB and the forest's carbon balance are uncertain, and will depend on how long it takes for heterotrophic respiration, mortality, and CUE to return to pre-logging levels.

Publication_Abstract: We used, eddy covariance to measure the net exchange of CO2 between the atmosphere and an old-growth tropical forest in Para, Brazil from I July 2000 to 1 July 2001. The mean air temperature and daily temperature range varied little year-round; the rainy season lasted from late December to around July. Daytime CO2 uptake under high irradiance averaged 16-19 mumol(.)m(-2.)s(-1) . Light was the main controller of CO2 exchange, accounting for 48% of the half-hour-to-half-hour variance. The rate of canopy photosynthesis at a given irradiance was lower in the afternoon than the morning. This photosynthetic inhibition was probably caused by high evaporative demand, high temperature, an intrinsic circadian rhythm, or a combination of the three. Wood increment increased from January to May, suggesting greater rates of carbon sequestration during the wet season. However, the daily net CO2 exchange measured by eddy covariance revealed the opposite trend, with greater carbon accumulation during the dry season. A reduction in respiration during the dry season was an important cause of this seasonal pattern. The surface litter was desiccated in the dry season, and the seasonal pattern of respiration appears to be a direct result of reduced forest floor decomposition during drought. In contrast, canopy photosynthesis was not directly reduced by the dry season, probably because deep rooting allows the forest to avoid drought stress.

Data_Application_and_Derivation: Biomass inventories can be used to directly estimate carbon stocks and assess net carbon balance during a several year interval. By comparing the results from the 2000 survey to the original IBAMA survey in 1984 we could determine the carbon balance of this forest over a 16 year period.
-
Quality_Assessment: The data have been carefully reviewed and there are no known problems with them at this time.
Estimates of total and commercial heights are considered accurate to within 1 meter. Measurements of diameter have an associated error of plus or minus 0.2 cm while the estimated diameter values have an associated error of plus or minus 1 cm.
-
Data_Acquisition_Materials_and_Methods: In March 2008 an 18 ha plot (300 m N-S by 600 m E-W) directly east of the tower (see accompanying map) was surveyed. A grid of transects 25 meters apart were established and for all trees with a diameter at breast height > 35 centimeters, diameter, commercial and total height, location within the plot, species common name and condition (live, dead, damaged etc.) were recorded. Where buttressing or heavy vine growth prevented an accurate measurement of diameter at 1.3 meters above the soil surface, diameter was either estimated (for deformed or vine laden trees) or measured above the buttress with the aid of a ladder. Total tree height and commercial height (height to the first bifurcation) were estimated to the nearest meter by experienced technicians. Along three East-West transects ( B, G and L), trees between 10 and 35 cm diameter within 5 meters of the transect were sampled. Height, diameter, location and species identification were measured as for the larger trees and recorded.
