Composição de mamíferos do Parque Estadual Lago Azul, Paraná

Abstract

The richness of mammals in Brazil is one of the greatest on the planet, however, forest fragmentation represents a major threat to terrestrial mammals. Based on concerns about forest development, use of natural resources and the richness of Brazilian fauna and flora, units such as parks have been established to promote conservation and protection of biodiversity in the country. The conservation of the ecosystem requires understanding of the organisms that occur in a certain place, so the fauna inventory can indicate the levels of environmental requirements and enable the development and implementation of any effective preservation project. In these terms, this study aims to understand the composition of mammals in the portion of Lago Azul State Park that covers the municipality of Campo Mourão - PR. The sampling of mammals was conducted using camera traps in four areas of the park: the Primitive Zone (ZP), Recovery Zone 1 (ZR1), Recovery Zone 2 (ZR2) and the area of the Power Generation Complex (CGH). The cameras were deployed for six months: October, November and December 2021, January, February and April 2022, totaling approximately 16000 hours of monitoring. After data collection, the absolute frequency and constancy of occurrence of each species was calculated. Throughout the PELA, 14 mammal species classified in 12 families and 6 different orders were recorded, among them, four invasive exotic species: Sus scrofa (Linnaeus, 1758), Canis lupus familiaris (Linnaeus, 1758), Felis catus (Linnaeus, 1758) and Lepus europaeus (Pallas, 1778); and three species classified as rare for this study: Eira barbara (Linnaeus, 1758), Galictis cuja (Molina, 1782) and Mazama gouazoubira (Fischer, 1814); in addition to the species Sylvilagus brasiliensis (Linnaeus, 1758), classified by the IUNC as vulnerable. We conclude, then, an urgency of management for the invasive exotic species, and the possibility that the recovery zones of the PELA, previously classified as provisional zones, are close to being classified as permanent zones.
