Description
Summary:The degradation of remaining forests is mainly caused by anthropic activities such as wood extraction and deforestation. In Ecuador, during the period 2016 and 2018, there was a loss of 115,000 of the native forest due to deforestation mostly produced in rural areas. A suitable alternative for the recovery of degraded landscapes is the ecological restoration, which allows to stop and reverse the damage provoked in forest ecosystems, in addition to the provision of ecosystem services. In this context, the following research contributes to the knowledge of processes of ecological restoration through the assessment of floristic composition, diversity and the analysis of the structure of areas that are under passive restoration. This study was carried out in Jamboe reserve, Zamora canton, Zamora Chinchipe province, where three plots of 50 x 50 m were randomly installed in areas of passive restoration with 10 years of abandonment after these were used as pasturelands. Inside each plot, there were identified and registered individuals with a DAP ≥ 5, to determine the specific richness, the Shannon diversity index and Sorensen index, as well as the calculation of the importance value index and the structural profiles. There were collected 52 species, 45 genres, 32 families, and an average diversity (H’). The areas of passive restoration are mastered by Miconia dodecandra (16,11 %), Vismia baccifera (12,97 %), Miconia calvescens (10,48 %), Piptocoma discolor (8,35 %), Psidium guajava (5,81 %), y Ficus máxima (4,8 %) species. In conclusion, passive restoration over a period of 10 years evidences the recovery of forest-structural attributes, reflected in composition, diversity, abundance, dominance, frequency, basal area and density characteristic of a piedmont forest, making this type of restoration strategy important in the recovery of degraded lands in the forests of southern Ecuador.
