With its shorter dry season, Manaus is in sharp contrast with the nearest site, Santarem. It doesn’t have the direct ocean influence (more than 1000 km from the Atlantic) as the Caixiuanã and has much less disturbance in the the vicinities vicinities ifif compared compared with Ji-Paraná. with Ji-Paraná.

Pioneer Pioneer studies studies conconducted ducted in in Cuieiras Cuieiras have have shown shown striking facts about the rainforest. striking facts about the rainforest. Prospects Prospects for for the the Future Future From From previous previous and and ongoing ongoing studies studies in in Manaus Manaus we we have have learned learned that that the the rainforest is not in equilibrium as once thought. It is rainforest is not in equilibrium as once thought. It is growing growing at at an an incredible incredible rate rate of of 55 tt C/ha C/ha y. y. UndersUnderstanding how is it possible (doubling biomass tanding how is it possible (doubling biomass every every 100 100 years!) years!) and and for for how how long long will will this this growth growth continue continue (C (C carrying capacity) carrying capacity) are are the the main main goals goals of several projects of several projects in in the the area. area. Also Also the direct and the direct and indiindirect rect effects effects of of this this high high C C sequestration sequestration on on the the atmosatmosphere phere and and climate climate need need further further clarification, which will clarification, which will come come through through the the disciplinary disciplinary integration integration found found in in LBA. LBA. Final Final Remarks Remarks Up Up to to the the present present the the overall overall area area has has been been undisturbed, undisturbed, even for large neighboring private properties. even for large neighboring private properties. INPA INPA has has some some control control on on the the issuance issuance of of logging logging permits permits in in the the area area (through (through an an IBAMA IBAMA committee), committee), which which should should mean mean an an effective effective restrain restrain in in future future disturbances disturbances and and develodevelopments. pments. With With the the recently recently acquired acquired status status of of Long Long Term Term Ecological Ecological Monitoring Monitoring Station Station and and with with aa flurry flurry of of related related and and multidisciplinary multidisciplinary research research projects projects starting starting in in the the area, area, itit is is likely likely that that Manaus Manaus becomes becomes one one of of the the most most stable stable and and integrated integrated sites sites in in LBA.
