Efetividade do reflorestamento para recuperação das margens de app da lagoa de Parnaguá

Abstract

The recovery of degraded areas is a fundamental strategy for environmental conservation and the protection of water resources. This study aimed to evaluate the effectiveness of reforestation with native species used to recover the banks of the Parnaguá Lagoon, located in the south of the state of Piauí. The methodology consisted of a field study with a qualitative-quantitative approach, encompassing the stages of nursery production, field planting, and species monitoring. For production, native species with potential for adaptation to the local environment were selected, using a substrate composed of manure and sand. After initial development, the seedlings were transplanted to the study area with adequate spacing. Monitoring occurred in two distinct periods, evaluating growth parameters such as height and diameter, as well as phytosanitary conditions. The results demonstrated positive growth and good adaptation to environmental conditions, with high survival rates. Among the species evaluated, the ingá tree showed the best performance. It is concluded that seedling production in nurseries, combined with field monitoring, is efficient for the restoration of riparian vegetation. The study demonstrates that such actions are essential to mitigate the environmental and social damage caused by deforestation, ensuring the protection of natural resources and the conservation of biodiversity in the Parnaguá Lagoon region
