Diversidad florística y estructura en tres áreas del bosque protector pedro franco dávila, recinto Jauneche, Cantón Palenque, año 2019.

With the objective of evaluating the floristic and structural diversity in three areas of the protective forest Pedro Franco Dávila, Jauneche enclosure, Palenque canton, province of Los Ríos, an inventory of 0,48 ha was carried out. Sampling units of 400 m2 were established in three sections of the forest: Bosque Sin Intervención (BSI), Bosque Poco intervenido (BPI) and Bosque Muy intervenido (BMI), in which the adult mass of the forest was evaluated (DAP 7,5 cm). Through indicators of species diameter and height, family, diversity, dominance and similarity indices, Ecological Importance Value Index (IVI) and Forestry (IVF), the floristic and structural diversity of the forest was determined. 319 individuals belonging to 27 families, 47 genera and 48 species with DAP 7,5 cm, being the most important families by the number of species Leguminasae with 9 species, Moraceae with 7 species, Aracaceae with 6 species and Anacardiaceae with 3 species. The Importance Value Index (IVI) indicated that the most representative species in the study areas were Anacardium excelsum with 10,89% in the BSI, Coussapoa villosa with 16,16% in the BIS, and Gallesia integrifolia with 10,01% in BMI. Shannon’s highest diversity index was 0,8993, indicating that the BSI has great species diversity, Simpson’s dominance rate was 0,9379, showing that the BIS had the highest dominance, while Jaccard’s similarity index between sections did not exceed 35% of similar species. The most abundant section was the BSI with 110 individuals and the sociological position of the heights between the specimens did not exceed 35 m in height. The largest diameter was recorded in diameter class VI with the species Gallesia integrifolia (palo de ajo), the general distribution of the individuals in the different diameter classes shows the shape of the normal distribution curve J, indicating that the forest is in a state of recovery. Keywords: Floristic diversity, diversity indices, dominance, similarity, endangered species
