Timber harvesting is an important economic activity in nutrient-rich floodplain forests (várzea) of Central Amazonia. In the Western Amazon basin of Brazil and Peru, access to terra firme forests is restricted due to the absence of a road network. Still, 60 90% of the local and regional markets are provided with timber obtained from the floodplain forests. Costs for logging are lower in the floodplain forests (US$ 6.73 m 3) as in the non-flooded terra firme forests (US$ 14.32 m 3) due to the easier access and lower energy costs. Timber harvesting is based on a forest management plan applying felling cycles of 25-35 year an diameter cutting limits of 50 cm. Tree-ring analysis (dendrochronology) is a powerful tool to determine tree ages and w...
