Medium and large-sized mammals in a remnant forest in the state of Rondônia, Brazil

The Brazilian mammalian fauna is threatened by several factors, the main ones being anthropogenic origins, such as agriculture, cattle ranching, and hunting. Medium and large mammals are continually affected by these factors. In this context, we conducted an inventory and estimated the abundance of medium and large mammals in a particular peri-urban remnant forest in the city of Porto, Rondônia. Fieldwork was carried out involving 88 kilometers of census during the daytime, indirect signs research, and interviews. We recorded 21 species of mammals. Private forest reserves have the potential to conserve endangered species, and therefore, actions that favor the connection of these areas in the rural environment should be prioritized
