Uso da matriz GUT na análise de Perturbações antrópicas em uma unidade de conservação urbana de Pernambuco

Abstract

The Mata do Passarinho Urban Forest Reserve (FURB) is a small urban UC with enormous value for society, as it protects part of the biodiversity of the Atlantic Forest biome where it is located. However, it suffers intense degradation through anthropic disturbances, which are changes in the environment resulting from human action. The objective of this work was to analyze, using the GUT matrix, which anthropogenic disturbances should be prioritized when developing solutions for them. The research took place at FURB Mata do Passarinho, in Olinda, Pernambuco. The identification and characterization of human disturbances was carried out through walks in the forest and photographic records. The application of the GUT matrix met the Severity, Urgency, and Trend criteria for each disturbance, scoring them from 1 to 5, and multiplying them together (GxUxT) to discover the GUT value of the disturbances. The results were: the identification of five (5) anthropogenic disturbances, including burning, deforestation, and solid waste; the GUT matrix; and the ranking list with the GUT value in descending order, showing the priority level of the disturbances. At the top of the ranking list, occupying 1st, 2nd, and 3rd places, with the highest GUT values, were burning, deforestation, and solid waste, respectively, indicating that actions to resolve these disturbances must be prioritized by management. Thus, this work enables a better understanding of the degradation suffered by FURB and provides useful information that supports managers' decisions in planning actions that aim to mitigate the environmental impacts that occur in the UC.
