RODRIGUEZ MATOS, Yuris et al. Behavior of carbon retained in urban trees in the south of the city of Guantánamo. Rev cubana ciencias forestales [online]. 2018, vol.6, n.3, pp.284-299. ISSN 2310-3469.

This work was developed in the south of the city of Guantánamo, belonging to the Provincial Communal Company, from november 2016 to december 2017, with the objective of evaluating the behavior of carbon retained in urban trees. The same was carried out through a floristic inventory, by means of a simple random sampling, where 16 variable transepts were raised, evaluating the existing tree species in the area that compose the shrub layer (1 to 4,99 m) and arboreal (greater 5 m). The diameter (m), height of the plant (m), basal area (m2), volume (m3), alpha diversity, with the horizontal structure was determined: relative abundance, relative frequency and relative dominance, as well as carbon sequestration. The results indicated that a total of 26 families, 36 species and 1 259 individuals were identified corresponding to the arboreal and shrub layer, where the species of greater abundance, frequency and relative dominance were: Coccothrinax argentea, Thevetia peruviana, Mangifera indica and Aleuritis moluccana and those with the best carbon retained CO2: Tabebuia angustata (19 395, 3), Aleuritis moluccana (17 725, 5) and Mangifera indica (11 711, 6).

Keywords : Urban trees; carbon sequestration and floristic inventory.
