O uso da biogeografia para análise ambiental do refúgio de vida silvestre dos rios Tijuco e da Prata em Ituiutaba (MG)

Abstract

Biogeography is an integrated way of looking at nature, considering the geographical distribution and the relationship of living beings with the environment and the human being is included. This way, Biogeography is the central theme of this research. The landscape is the physical environment in which Biogeography takes place. This research was developed in the municipality of Ituiutaba (MG) and because it is in the Domain area of the Brazilian Cerrado, this one suffered with the advancement of agriculture and other anthropic activities, which brought accelerated environmental degradation. Thus, what still remains of native vegetation in the municipality is mostly in the vicinity of water courses in the region. As it is known that there are remnants of Atlantic Forest in Ituiutaba (MG) in the Conservation Unit of Refúgio de Vida Silvestre dos rios Tijuco e da Prata in Ituiutaba (MG) (which includes other municipalities), this research was proposed. The present work has as main objective to evaluate the state of conservation and anthropic pressure in the Refúgio de Vida Silvestre dos rios Tijuco e da Prata in Ituiutaba (MG). The specific objectives are, a) to understand the environmental dynamics that allow the existence of Atlantic Forest in the Cerrado in Ituiutaba; b) identify the vegetative species of the study area; c) to point out the use and occupation of the soil around the reserve area and the possible impacts on the survival of the species. The methodology adopted in this work has undergone the following phases: 1) bibliographic research, 2) environmental agency research on the area of the refuge, 3) choosing an area for field work and field work, 4) analysis of the information obtained in the field. The methodology adopted for vegetation analysis was the methodology of Passos (2003), but due to the difficulty in identifying the species, this research was compromised. In the case of the existence of Atlantic Forest in the Cerrado, it is common to find Atlantic Forest in the areas of Cerrado Forest. The wildlife refuge was created precisely because of the existence of this remnant of native vegetation. However, it is an area that needs to be monitored and have its own headquarters, because due to the presence of agricultural activities in its surroundings is threatened by the presence of animals, possible attack of invasive species and accelerated erosive process.
