Inventariamento de mamíferos terrestres de médio e grande porte em áreas de recuperação do Parque Estadual Lago Azul, Paraná, Brasil

Abstract

The survey of mammals is important not only for understanding of distribution and autoecology of species, but also as a measure of environmental integrity and as a basis for management actions, especially when it’s occurs in protected areas. This study aimed to survey terrestrial mammal species of medium and large size in recovery areas of Parque Estadual do Lago Azul (PELA), Campo Mourão and Luiziana cities. We employed the following species survey techniques: cameras traps, footprints plots and opportunistic records. Samples were collected monthly during the period January to June 2013, and always occurred in three sampling points. We evaluated the level of vulnerability of species and the occurrence of invasive alien species from consulting of bibliography. We recorded 16 species in 13 families and 6 orders. Five species presented greater constancy of occurrence: three natives (Nasua Nasua, Procyon cancrivorus, and Dasypus novemcinctus) and two invasives (Sus scrofa and Canis lupus familiaris). Seven species were considered with some degree of threat (Leopardus pardalis, Chironectes minimus, Cuniculus paca, Tapirus terrestris, Mazama americana, Mazama gouazoubira, and Dasyprocta sp.). The native species recorded in PELA indicate compatibility with regenerating areas. However, the constant record of invasive alien species becomes a concern, requiring that management measures are made.
