The property was subsequently expanded in 2003 with the addition of three other protected areas (Anavilhanas National Park, Amanã Sustainable Development Reserve, and Mamairauá Sustainable Development Reserve). The classification of these four sites developed into the current property entitled Central Amazon Conservation Complex. The Sustainable Development Reserves are linked to the State, and managed by the Amazonas State Conservation Units Centre (CEUC). To ensure the conservation of the protected areas, protection plans are implemented by the various responsible agencies. All protected areas of the property are also part of the Biosphere Reserve, which comprises, with other areas, the "Mosaic of Protected Areas of the Lower Rio Negro."
