Malinowski Biological Station (MBS) is located at the confluence of the Malinowski and Tambopata rivers in southeastern Madre de Dios river basin. The site includes the Malinowski guard post, which is staffed by SERNANP (the Peruvian government agency in charge of protected area management, akin to the U.S. National Park Service) and controls access to the 275,000 hectare (2750 km2 / 1061 square miles) Tambopata National Reserve and the adjacent 1-million hectare (10,000+ km2 / 4200+ sq. miles) Bahuaja-Sonene National Park. Together, the two protected areas encompass a vast expanse of virtually untouched, barely explored lowland Amazon rainforest.
Malinowski Biological Station is located on upland tierra firme habitat ~25m above the Tambopata River, with picturesque views of the river from atop the tierra firme terrace. A 2km trail leading from the station provides access to mature “old-growth” tierra firme forest habitat, and ends at a mammal clay lick. Across the river, a 3km trail begins from the river bank, passes through a band of early-stage successional forest, and traverses through a wide swatch of mature “old-growth”floodplain forest, ending at an oxbow lake.
