Cocha Cashu Biological Station (Estación Biológica Cocha Cashu or EBCC) is a tropical biological research station located at 11° 54'S and 71° 22'W in Manú National Park, Peru. It was established in 1969-70, predating the founding of its containing national park (est. 1973). Though only 10 km2 in area, the site has provided valuable research.[1] The station is situated on the shore of an oxbow lake, from which it takes its name. "Qucha" (in hispanicized spelling cocha) is the Quechua word for lake. "Cashu" is derived from the English word "cashew" and refers to the shape of the lake.[2]
