| Sumario: | Different factors such as rapid urbanization and the excessive use of fossil fuels for economic activities carried out within cities have contributed to the increase in Greenhouse Gases (GHGs), with CO. being one of the main GHGs causing the increase of temperature on Earth and, as a consequence, Climate Change. Nowadays, strategies such as capture of CO2 by the trees in urban public parks have been implemented within cities to reduce and mitigate the effects of this atmospheric gas. The objective of this work was to determine the tree diversity and amount of CO2 that is currently captured in the Zazil Ecological Park in the city of Chetumal, Quintana Roo, Mexico. For this, a forest survey was carried out on an area of 4.5 ha corresponding to the trees within the park with information on specimens with diameters greater than 7.5 cm, recording the normal diameter (1.30 m from ground level) and total height. From these data, 71 species and 32 families distributed in 2366 individuals were identified. Diversity and richness were evaluated using the Margalef index (D Mg) registering a value of 9.01, the Menhinick index (D Mn) presenting a value of 1.45 and the Simpson index (1-D) with a value of 0.50, which show a high diversity in the park. In addition, the biomass was determined and, through it, the carbon content was estimated by applying a conversion factor of 4.7 %. These data were converted to CO2 using the constant 3.67. Results showed a total of 215.339 t-CO2-e/ha captured in the trees of the Zazil Ecological Park, which is comparable to captured quantities reported in other studies. The information generated contributes to the design of urban parks and conservation of their trees as mitigation strategies, through carbon capture at the city level.
