Resumen
This research aimed to determine the composition and structure in two types of forest, in the foundation Sumak Kawsay In situ, located in the town of Mera, Pastaza province. The composition and structure were determined, as well as, the floristic diversity according to the value of importance index and biodiversity index, and finally comparing the two types of forest. 5 transects of 50 x 4m in the two forests were established, giving a total area of 2000 m², the diameter at breast height (DBH) and the height of species greater than 10 cm. The respective calculations regarding the importance value index through the Past program for the Diversity, Simpson's and Sorensen's indexes were applied. In the results obtained, it was determined that forest 1 was represented by 238 individuals that corresponded to 44 species, 37 genders and 18 families; 185 individuals were obtained which corresponded to 48 species, 42 genera and 20 families in forest 2. In both types of forest, it was found the same species as the dominant Ficus trigona L. f., this referred to the fact that they were the same type of forest with certain changes of very small stages, different ages. In terms of its structure, there was a domain of young stems represented by their distribution, which deduced that they were secondary forests, since the study area had been affected by floods because they were adjacent to a water network and therefore became temporary because there had been a disturbance environmental. It is recommended to expand the studies regarding the forests of the foundation SumaK Kawsay In situ, focusing primarily on forest dynamics, in secondary succession, to obtain more parameters that support its management and conservation.
