Abstract. Composition and relative abundance of the medium-large sized mammals of Turvo State Park, Rio Grande do Sul, Brazil. Between January of 2005 and December of 2006, studies on the composition and relative abundance of medium and large sized mammals were carried out in Turvo State Park. Records came from camera-trapping, in addition to visualization and presence and absence data from track surveys along pre determined transects. At total, 29 species of medium-large sized mammals were listed. Of these, Dasyprocta azarae Lichtenstein, 1823 and Sylvilagus brasiliensis (Linnaeus, 1758) were the most frequently found. For carnivores, the majority of records were for Nasua nasua (Linnaeus, 1766) and Leopardus pardalis (Linnaeus, 1758), whereas Leopardus tigrinus (Schreber, 1775), Leopardus wiedii (Schinz, 1782) and Galictis cuja (Molina 1782), had the least. Among the ungulates, only Pecari tajacu (Linnaeus, 1758) showed frequent records, ranking fourth overall. Some species, common to other environments, showed few records at Turvo State Park, such as Dasypus novemcinctus Linnaeus, 1758 and Didelphis albiventris Lund, 1840. Data was suggestive of the probable local extinction of  Tayassu pecari (Link, 1795) in the Park. The conservation of the medium and large sized mammals of this conservation area is strongly associated with the conservation of the “Misiones Green Corridor”, which probably represents a source area for many species.
