Diversity, structure and ecosystem services of trees in four parks in Texcoco using i-Tree Eco. Rev. mex. de cienc. forestales [online]. 2021, vol.12, n.67, pp.202-223.  Epub 25-Oct-2021.

The purpose of this work was to know the structure and diversity, and ecosystem services provided by the trees at four parks in the city of Texcoco de Mora. A census and analysis of the tree composition in the green areas was carried out. A tree population composed of 391 individuals belonging to 19 families and 34 species was determined. The most common species were Ficus benjamina (23 %), Schinus molle (13.8 %), Hesperocyparis lusitanica (10.2 %), and Ligustrum lucidum (10 %). Simpson’s index (1-D) had a value of 0.73, and the Shannon-Wiener index (H') equaled 3.89, which indicates a high diversity. The three most abundant species recorded do not comply with 10-20-30 rule. The i-Tree Eco v6 software was used to estimate that the trees store 28.85 Mg C ha-1, capture 2.56 Mg C yr-1, produce a total of 6 Mg O yr-1, remove a total of 0.06 Mg yr-1 of pollutants, and contributes to reduce runoff by 107.9 m3 yr-1. This information is useful for the management and tree conservation, as well as in the valuation of trees in the city of Texcoco.
