Ducke Adolfo Ducke Forest Reserve

Adolfo Ducke Forest Reserve (Reserva Florestal Adolpho Ducke) is 10,000 ha protected area on the outskirts of Manaus, Brazil. It is a member 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 may serve as a basis for biodiversity surveys in other areas of the Amazon region, and to study the impacts of fragmentation. The grid of LTER sites is made up of 25 km2 plots inserted into a larger grid of 64 km2 plots.
