ESPARZA OLGUIN, Ligia Guadalupe  and  MARTINEZ ROMERO, Eduardo. Diversity and carbon storage in the Permanent Forest Area of Álvaro Obregón, Calakmul, Campeche. Rev. mex. de cienc. forestales [online]. 2018, vol.9, n.45, pp.152-186. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v9i45.141.

Permanent Forest Area (AFP) in Álvaro Obregón, Calakmul has semi-evergreen tropical forests that have been exposed to forest management. Considering the importance of these tropical forests as reservoirs of carbon and biodiversity, the objective of this study was to analyze tree diversity, accumulation of biomass and carbon capture in different types of semi-evergreen tropical forests (medium forest - SMSP and floodable forest - SI). Circular plots of 1 000 m2 where used, in which tree species were tagged, measured (height and diameter at 1.30 m) and identified. The AFP that has been in the recovery period for more than 20 years. A richness of 90 species was found in the SMSP, with densities between 5 170 to 3 720 ind ha-1, with intermediate diversity (H) (2.8 to 2.65). In the IS, 75 species were found, with a high density (5 920 to 8 630 ind ha-1), and a high diversity (H) (3.02 to 3.06). The average structural diversity (Hsdh) was low for SMSP and SI, with carbon values between 16.6 and 37.17 MgCha-1 in SMSP and 36.44 to 44.58 in SI. It is concluded that the semi-evergreen tropical forests analyzed are in the process of recovery, with processes of regeneration and capture of carbon important for the conservation of diversity.
