| description | Given the determining factor that constitutes land use change (LUC) upon biodiversity loss and environmental deterioration, cocoa-shade agroforestry systems can represent an important land area for biodiversity conservation and carbon storage. The aim of this study was to investigate the effect of the age of the cocoa agroforestry systems on their shade tree diversity and carbon stocks. Two-hundred and fifty-eight plots were compared in eleven cocoa plots between 10 and 70 yr-old, totalizing 7.87 ha. The normal tree girth (DN) and total height of all trees > 5 cm DN were measured, and their estimated biomass were compared using a general and a species-specific allometric equation to know the discrepancy between both methods. The 70 yr-old plantations presented more species per hectare (23), Shannon diversity index (2.0) and carbon storage (75 Mg ha-1) than the 10 yr-old plantations (p < 0.01; mean values of 10 Mg ha-1, 1.1 Mg ha-1 and 36 Mg ha-1; respectively). Specific allometric equations estimated 27.7% (p = 0.05) more aboveground biomass than the general equation, so they are considered as more precise to this specific agroforestry system and hence are recomended. It is concluded that, particularly for México, conservation of mature cocoa-agroforestry systems contribute to the conservation of tree biodiversity and carbon stocks of tropical vegetation, resembling relics of the original vegetation. |

Ante el impacto que representa el cambio de uso de suelo en la pérdida de biodiversidad y deterioro del medio ambiente, los sistemas agroforestales de cacao de sombra son una alternativa para la conservación de biodiversidad y almacén de carbono. El objetivo de este trabajo fue conocer el efecto de la edad de los sistemas agroforestales de cacao en la diversidad arbórea y almacenes de carbono de su vegetación de sombra. Se compararon 258 parcelas distribuidas en once sistemas agroforestales entre 10 años y 70 años, totalizando 7.87 ha. Dentro de cada parcela se midió el diámetro normal (DN) y altura total de todos los árboles >5 cm (DN) para estimar su biomasa aérea con una ecuación general y otra específica, y conocer la discrepancia de ambos métodos. Los sistemas agroforestales de 70 años presentaron en promedio más especies arbóreas por hectárea (23), índice de diversidad Shannon (2.0) y almacén de carbono (75 Mg ha-1) que los de 10 años (p < 0.01; 10 Mg ha-1, 1.1 Mg ha-1 y 36 Mg ha-1; respectivamente). La ecuación alométrica específica estimó 27.7% (p = 0.05) más biomasa aérea que la ecuación general, por lo que se considera de mayor precisión para estos sistemas agroforestales en particular, y se recomienda su uso para estos tipos de vegetación. Se concluye que, particularmente para México, conservar sistemas agroforestales de cacao de edad madura contribuye a la conservación de la biodiversidad arbórea y almacenes de carbono de la vegetación tropical, asemejando relictos de la vegetación original.
