Description

Biomass and components of productivity for several types of tropical forest were determined for a number of study sites around Manaus, Brazil, from 1963 to the present. The study sites include several (0.2 ha) stands of terra firme (dry land) forest at "km 64" to the northeast of Manaus, towards Itacoatiara (approximately 3.0 S 59.7 W, near the "Walter Egler" Reserve), riverine forest in the 10 km x 10 km "Ducke Reserve" (2.95 S 59.95 W, 26 km north-northeast of Manaus city centre on the Itacoatiara road), varzea forest subject to inundation at Rio Tiruma Mirim (approximately 3.0 S 60.0 W, about 20 km west of Manaus on a small tributary of the Rio Negro), and more recent study sites at Bacia Modelo, 80 km north of Manaus (approximately 2.57 S 60.12 W) and approximately 50 km north of Manaus (2.50 S 60.08 W).

Detailed data on biomass and nutrient content of different forest components at "km 64" are available from studies carried out for the International Biological Programme in 1970 (together with data from 116 other forest sites; much of these data are also contained in the IBP Woodlands Data Set maintained by the ORNL DAAC).

Total annual litterfall ranges from 640 to 800 g/m2, giving a minimum estimate of above-ground net primary productivity (NPP). Most studies of NPP around Manaus have been carried out by or under the auspices of the Brazilian National Institute of Amazon Research (INPA). A small Landsat satellite image of Manaus, showing the location of INPA and the Ducke Forest Reserve, may be found on the Ducke Reserve home page. Much of the research work on NPP has also involved the participation of the Max Planck Institute of Limnology, Germany.
