The objective was to evaluate and compare structural and floristic characteristics in two secondary areas of agricultural and livestock activities in Zungarococha, as well as identify and classify species of floristic composition according to their use. The study was carried out in rectangular plots where structural and floristic parameters were collected via inventory. The results show that the composition in agricultural and grassland areas were characterized by the dominance of few tree species, where richness was greater in the grassland area compared to the agricultural area, however, the rarefaction curve and the diversity index did not shows significant difference between the two types of vegetation. Furthermore, the forest structure, which considers density, dominance and frequency of species, indicates that the two areas present quite similar horizontal structural characteristic...

The degradation of Amazonian landscapes due to extensive cattle ranching is a widely recognized problem, but restoration actions are still insufficient, partly due to the limited understanding of the processes that drive the recovery of their ecological integrity. This study evaluated the natural recovery of post-grazing secondary forests in an area near Iquitos (Peruvian Amazon), analyzing ecological integrity through species composition and diversity, recruitment, and basal area, in relation to land use intensity and the structure of the surrounding landscape. Ecological indicators of all trees and palms with a diameter at breast height (DBH) ≥ 3 cm were recorded in ten 500 m² plots with ages between 17 and 38 years of secondary succession. The results revealed low values of species richness (17-28 species) and basal area (0.56-1.47 m²). The analysis of these indicators showed hete...
