Jaú National Park - Brazil
Jaú National Park
population and community ecology
Jaú National Park extends over 22.720 km2 and is located 220 km NW the city of Manaus, at approximately -01º54’ and -61º27’. It includes upland forest (terra firme), white-sand forest (campinarana) and black-water inundation forest (igapó). The igapó forest under study is mostly pristine, and subject to annual floods of up to 9 m through the oscillating water-levels of the Jaú and Negro Rivers. The species-rich igapó forest contains several endemic tree species, some of which grow at extremely flooded sites and with individuals that have ages of up to 1,000 years, as measured by dendrochronological analyses. The monitoring of wood growth, mortality, and regeneration in these tree species indicate how tree populations react to intensified flood and drought regimes, how they are predicted to occur under global climate change.
General Characteristics, Purpose, History
Jaú National Park was established 1980, and is, together with two other central Amazonian conservation units (Mamirauá and Amanã Sustainable Development Reserves), part of the UNESCO II Central Amazon Conservation Complex (established in 2000 and expanded in 2003). Botanical and ecological studies focusing at floodplain and white-sand forests were performed during the 1980ies and 90ies mainly by researchers of the National Institute for Amazon Research (INPA, Manaus). In 2012, PELD-MAUA established several permanent floristic inventories in black-water inundation forests (igapó) of the Jaú River, to monitor growth, mortality, and regeneration of selected tree species as well as to perform ecophysiological studies on herb and tree species.
