Adolpho Ducke Botanical Garden

The Adolfo Ducke Forest Reserve is a 10,000-hectare protected area of the Amazon rainforest on the outskirts of the city of Manaus, Brazil.

The reserve was established in 1963 in honour of the entomologist and botanist Adolfo Ducke, who was one of the most respected experts on Amazonian flora. It is part of the Long Term Ecological Research Network. The reserve sits at the intersection of two major drainage areas, the Amazon River and the Rio Negro. The reserve is made up of research plots designed to study the biota of the regions, which serve as a basis for biodiversity surveys in other areas of the Amazon region, and studies on the impacts of fragmentation. The grid of LTER sites is made up of 25-square-kilometre plots inserted into a larger grid of 64-square-kilometre plots. Within the grid, which is used for straight line transect surveys of biodiversity, there are 250-metre long permanent survey plots.
