We are currently installing 2 plots in the Ducke Reserve in Brazil, one in a baixio (low point in topography and other in plateau forest). Both represent the beginning of 10 permanent sample plots which will be monitored for INPA researchers/students.
The study is conducted at Reserva Florestal Adolpho Ducke (RFAD) of the Instituto Nacional de Pesquisas da Amazônia (INPA), located near Manaus (02°55′S, 59°59′W).
The reserve covers 10 000 (10×10 km) hectares of terra-firme tropical rain forest, with a closed canopy 30–37 m high and emergents growing to 40–45 m. The understorey is characterized by abundant sessile palms,such as Astrocaryum spp. And Attalea spp. Mean annual temperature is around 26°C and mean annual rainfall is 2362 mm, with a dry season between July and October. Soils are derived from tertiary marine sediments from the Barreiras group. Soils represent a continuum from clayey latosols on the ridges, becoming sandier as the inclination increases and altitude decreases until the mineral fraction in the bottom lands is almost pure sand.
We have installed measurements for below-ground, above-ground NPP monitoring and CO2 efflux measurements.
The fieldwork is leaded by Flavia Costa, Beto Quesada (INPA researchers). Jhon del Aguila, an IIAP (Research Institute of Peeruvian Amazon) researcher, is training them in long-term data collection. He has previous worked at the Allpahuayo site near Iquitos, Peru.
The research goals are to understand the effects of soil, topography, weather and watershed position on the carbon cycle in these forests.
