Modelo heterogêneo de espécies arbóreas nativas para recuperação: avaliação metodológica e inferências ecológicas, Uberlândia, MG

Abstract

This study sought to understand and improve techniques applied to the ecological restoration of an area that was a path. The area under study was a degraded vereda present in the city of Uberlândia - MG, and an area to be recovered is 3,6277 ha. The methods used for the recovery of the area were monitored, which included, plant of mixed native species with or without hydrogel, application of fertilizer, control of invasive grass and rustification. There was an assessment of the environmental conditions and the rate of certain species planted in the area, and how they responded as ecological interferences and methodological impositions. It was observed that the species Anadenanthera colubrina (Benth.) Brenan, Enterolobium contortisiliquuom (Vell.) Morong and Psidium myrsinites DC had better survival rates. Through ANOVA statistical tests it was possible to observe the conditions of surface humidity of this path, dividing it into edge, middle and bottom and, in addition, with the use of non-parametric Kruskal-Wallis statistical test it was possible to compare the humidity surface area of the study object with that of two other similar areas, but with native vegetation mostly woody, in order to assess the area's capacity and resilience to support a new plant community. Concluding that the combination of restoration methods presents itself as an effective methodology for ecological recovery, however, that of observing the original ecological conditions of the habitat before starting the interventions.
