Elaboração de plano de recuperação de área degradada em Lagoa da Confusão-TO

Abstract

Over the years, environmental degradation has been occurring in an accelerated manner, it was causing several damages to the environment, such as habitat fragmentation, soil erosion, extinction of biodiversity, degradation of ecosystems and climatic changes. With this, it is extremely necessary that there be a plan or project with the intention of restoring these areas, it was maintaining their biodiversity and ecological balance. This work had the objective of elaborating a Plan for the Recovery of Degraded Area (PRDA) in rural property located in the municipality of Lagoa da Confusão, State of Tocantins, and it belonging to the Cerrado Biome. The study was based on a permanent preservation area of 5.76 ha, in a state of degradation, because it was used for agricultural activities, located at Fazenda São João. All the necessary steps were list to prepare the recovery project, which included : evaluation of degraded areas, opening of pits and crowning, and revegetation of the area under study. The technique chosen to effect the recovery of the degraded area was of enrichment of seedlings and dense planting, to restore the diversity, structure of the forest, to accelerate the succession and to make it more attractive the fauna. A total of 19 native species were selected and their ecological group (i.e.: pioneer, initial secondary), tolerance to soil moisture, their occurrence and attractiveness to fauna. Some examples of these species are: laranjinha do cerrado, vermelhão, jenipapo, buriti, mari-mari, amescla, among others. The time required to implement the plan is 10 months until the final monitoring / follow-up phase. The success of PRDA will bring several benefits to the environment, such as soil stabilization and fertility, preservation of water resources and increased interspecific relationships.
