The present research project was carried out with the objective of diagnosing the floristic and structural composition of the secondary native forest of Jalligua Alto, Cotopaxi province. For which seven sampling units were installed, the area covered by the secondary forest was considered, at a height greater than 1000 meters above sea level. Indicators of diameter, total height of individuals, species, family, importance value index (IVI) were used to demonstrate the floristic composition and structure of the vegetation. In this study they registered a total of 637 individuals belonging to 47 species and corresponding to 30 families, Lauraceae being the most diverse, with 6 species, followed by the Meliaceae family, with 4 species. The most abundant species was Cecropia sciadophylla Mart., Followed by Croton lechleri Müll.Arg. and Trema micrantha Blume. However, from the ecological point of view, the Guarea trichiloides L. species is the most important in the area with 29.85%, due to its dominance (greater basal area). According to the Shannon index, a value of 2.95 was obtained, showing a significant floristic richness, in addition, the similarity index 0 was obtained, which means that 0% of the species registered in the Secondary Native Forest of Jalligua Alto are found Between the 7 plots made and 100% they are different, so it can be said that there is little similarity in the floristic composition of the forest. In the study area, 71 timber trees greater than 7.5 cm in DBH were recorded, with a basal area of 3.76 m2, a total volume of 79.17 m3 and a commercial volume of 48.15 m3, the highest volume belongs to G. trichiloides, with 24.11 m3 followed by Nectandra sp with 17.32 m3. Keywords: heterogeneity, strata, sampling units, dominance. |
