Contextualization: The floristic analysis of the components associated with the cocoa crop is considered as a keystone to design relevant agroforestry models.

Knowledge gap: In the Pacific Coast of Nariño, traditional agroforestry systems of cocoa have a diversity of secondary species; however, there are few studies that have identified and characterized their economic and environmental benefits.

 Purpose: The objective of this research was to characterize the woody species existing in traditional cocoa agroforestry systems (Theobroma cacao L) of four community councils: Alto Mira, Bajo Mira, Río Chagüí and Las Varas, in the municipality of Tumaco, Nariño. It was developed within the framework of the project called “Study for the improvement of productivity and sensory quality (aroma and flavor) of cocoa (Theobroma cacao L) regional department of Nariño”, in which an inventory of the different tree species was made, and the diversity of these systems was determined by means of the Shannon and Simpson index (D).

Methodology: 22 sampling plots, of 400 m2 each one, were inventoried. Richness, density, basal area, frequency, dominance, abundance, and the index of ecological importance value (IVI) were determined. Finally, diversity was determined using Shannon's and Simpson's indices.

Results and conclusions: 150 specimens of woody plants were found in the four councils, concentrated in 27 species. The community council Las Varas had the highest density with 0.014 ind/m2; there, the species with the highest number of individuals per family were Tabebuia rosea, Cedrela odorata y Cordia alliodora. The families that stood out the most for their abundance were Rutaceae, Moraceae, Meliaceae, Annonaceae and Sapotaceae. The species with an outstanding importance due to their value index were Cedrela odorata, Cordia alliodora, Pouteria sapota y Tabeuia rosea. Finally, in the Shannon and Simpson indices there were no significant differences; however, Las Varas council was prominent for its greater diversity of species, due to the different studies of implementation and evaluation of agroforestry arrangements that have been established in the area.
