PRIETO-DUARTE, Jorge Luis et al. Characterization of the floristic biodiversity of a farm of the southern circuit in Cumanayagua, Cienfuegos province, Cuba. Pastos y Forrajes [online]. 2024, vol.47  Epub 27-Dez-2024. ISSN 2078-8452.

Objective: To characterize the floristic biodiversity of a farm of the southern circuit in Cumanayagua, Cienfuegos province, Cuba.

Materials and Methods: The study was carried out on a farm in Cumanayagua municipality, Cienfuegos province. The soil corresponds to the Brown type, without carbonate, typical red rendzina subtype (XIII A). The biodiversity monitoring methodology was applied with the use of transects designed from satellite photos. All flora species were surveyed and indices of relative abundance, origin, endemism and invasive potential were determined. Floristic biodiversity was characterized and biodiversity indicators (specific richness (S), Margalef’s diversity index and Simpson’s dominance) were evaluated.

Results: The farm has a total area of 67,1 ha, of which 38,6 % is under active exploitation. The main use includes miscellaneous crops (8,9 %), silvopasture (61,4 %) and animal husbandry (7,5 %). A total of 215 individuals and 321 species were identified, with a Margalef diversity index of 5,45. Simpson’s dominance was 0,01, indicating the absence of significant dominance. Simpson’s diversity index was 0,99, classified as high. The most represented families were Fabaceae (9,6 %), Malvaceae (6,5 %) and Cyperaceae (6,2 %). Six unique species were found, each belonging to a different botanical family. These unique species showed the floristic richness and genetic variability of the area.

Conclusion: The ecosystem shows high biodiversity and species diversity, with low dominance of any particular species. These characteristics are desirable and suggest that the ecosystem is robust and healthy, with good capacity to resist environmental changes and maintain its ecological functionality.
