Abstract: * Autor correspondente: guilirous@yahoo.ca RESUMOAs florestas ripárias provêem serviços ecossistêmicos essenciais à humanidade, mas estão sendo degradadas em um ritmo acelerado na Amazônia. Esse estudo teve como objetivo quantificar os estoques de carbono acima e abaixo do solo de florestas ripárias com quatro níveis de degradação (muito alta, alta, média e baixa) em duas microbacias (Rio Pepital e Rio Grande) em Alcântara (Maranhão), na Amazônia Oriental. Foram instaladas 24 parcelas permanentes de 1.000 m 2 … Show more

“…The watersheds examined in this study are illustrative of this problem. The degradation process begins with the removal of large trees for timber and charcoal production (Zelarayán et al ., ); the impoverished forests are then cut and burned, and the cleared land is used for subsistence agriculture and then abandoned until a regenerated fallow is burned again (Celentano et al ., ), resulting in a mosaic of areas in different levels of degradation.…”

“…Soils are classified as Plinthosols, naturally poor in nutrients (Anjos et al, 1995). Young secondary forests dominate the landscape, but small fragments of old-growth forest also remain (Zelarayán et al, 2015). The rural population of the study area is very poor and relies mainly on slash-andburn subsistence agriculture, which is the main cause of riparian forest degradation (Celentano et al, 2014).…”
