Estimativa de carbono armazenado em áreas de reabilitação ecológica da Empresa Danco Comercio e Indústria de Fumos LTDA

Abstract

The effectiveness and functioning of the restoration actions, monitoring is configured as a fundamental tool to evaluate it. In this sense, studies of floristics and phytosociology in such areas obtain results that indicate whether there should be interference in the study area, or whether the restoration action is fulfilling its objective. The present study took place at the company Danco Comercio e Indústria de Fumo Ltda, in the municipality of Governador Mangabeira, where three ecological restoration actions with 0.2 ha each were studied, in two of the company's farms. At Fazenda Capivari, two areas surveyed called Small Dam (FCBP) and Barragem Grande (FCBG) and at Fazenda Santo Antonio do Retiro, an area was surveyed, named Fazenda Retiro (FR). In each area, 20 plots of 100 m2 were sampled. Floristic and phytosociological studies were carried out, and carbon storage was evaluated by species and by area. The Retiro Farm (FR) was found, which stood out among the others in terms of floristics, with the highest number of individuals and species, a fact that is related to its location close to a forest fragment, thus facilitating the entry of new propagules . Regarding carbon storage, the area with the highest values of stored carbon was Fazenda Capivari Barragem Grande, with a total of 31.02 t/ha. The species that most stored carbon were Joannesia princeps, Ziziphus joazeiro, Schinus terebinthifolia and Inga edulis, with emphasis on Schinus terebinthifolia that appears in the three restoration actions among the main carbon stores.
