SANCHEZ FONSECA, José; RODRIGUEZ MATOS, Yuris  e  GARCIA SERRET, Manuel. Ecological vulnerability in a low altitude rainforest on metamorphic rocks. Rev CFORES [online]. 2023, vol.11, n.2  Epub 02-Set-2023. ISSN 2310-3469.

The research was carried out in a low altitude rainforest on metamorphic rocks, Baracoa Conservation Department, Alejandro de Humboldt National Park (PNAH), in the period from January 2020 to December 2022, with the objective of evaluating ecological vulnerability through the modification of the methodology established by the Civil Defense. Previously in 2015, some researchers established and geo-referenced 36 plots of 0.05 hectares. In those 36 plots selected the number of individuals by species and by strata were determined. The structural parameters, the ecological importance value index, and the Simpson index were characterized. The results showed that the analysis of floristic diversity facilitated the assessment of the structure, composition and behavior of the forest. The use of the proposed indicators was feasible for the evaluation of ecological vulnerability in the forest; the methodological proposal was modified from ecological indices with output in thematic maps, to plan rehabilitation and restoration actions. The forest presented low ecological vulnerability. The species Hibiscus elatus. Sw, Calophyllum antillanum. Britton, Guarea guara. Jacq, and Jambosa vulgaris DC were the least vulnerable taxa, and the most vulnerable Mangifera indica L, Ocotea leucoxylon. Sw, Zanthoxylum martenicense. L and Brya ebenus. L.
