HERNANDEZ-DZIB, Germán Alberto et al. Tree diversity, use and carbon stocks in productive restoration areas in Calakmul, Campeche. Ecosistemas y recur. agropecuarios [online]. 2021, vol.8, n.3, e2821.  Epub 31-Out-2022. ISSN 2007-901X.  https://doi.org/10.19136/era.a8n3.2821.

Tropical forests of the Calakmul Biosphere Reserve (REBICA) are home to high biodiversity and provide diverse ecosystem services threatened by the advance of the agricultural frontier. Productive restoration (RP), as a strategy that articulates the needs of producers and the conservation of natural resources, was implemented in modules in the ejidos Benito Juárez II (BJ), Eugenio Echeverría Castellot I (EEC) and Los Angeles (LA), adjacent to the REBICA. The aim was to evaluate a baseline for long-term monitoring of the impact of restoration actions on tree diversity, its use and stored carbon. The ejidos EEC and LA were associated with agroforestry systems, while in BJ a silvopastoral system was implemented, estimating densities of 1 713 ind ha-1, 3 144 ind ha-1 and 1 717 ind ha-1 respectively. True diversity (1D) ranged from 24.63 in LA to 15.13 in EEC and 13.47 in BJ. Sixteen potential uses were recognized for the identified species of which 47 were protected under CITES, IUCN and NOM-059 lists. The carbon values corresponded to 6.96 Mg C ha-1 in BJ, 10.32 Mg C ha-1 in EEC and 34.40 Mg C ha-1 in LA. The variations in composition, structure, biomass and carbon estimated indicate that the estimation of this baseline will facilitate the generation of a monitoring program that will allow evaluating the impact of the restoration actions implemented and, where appropriate, modifying them to accelerate the recovery of the analysed attributes.
