All research is conducted at the Los Amigos Biological Station, a research station located in lowland Amazonian forests in the Madre de Dios Department of Peru. The station is commonly referred to by its Spanish acronym – CICRA (Centro de Investigación y Capacitación Rio Los Amigos). The site was established in 2000 by the Amazon Conservation Association (ACA) and its Peruvian partner Asociación para la Conservación de la Cuenca Amazónica (ACCA). The station is located on a high terrace at the confluence of two rivers – the Madre de Dios and Los Amigos Rivers.
CICRA is one of the most active research sites in the Amazon basin and has hosted over 200 research projects to date. The site is rich in biodiversity, with more than 4,600 species recorded at the site to date, including 11 primate species, 5 felid species, and over 500 bird species. CICRA has a large trail system, with >50 kilometers of marked trails. The station also houses a dining hall, where researchers and visitors enjoy communal meals, classroom space, large offices and labs, a library with field guides to all local plants and animals, two dormitories, and several cabins.
The site boasts a variety of attractions, including a 60 meter observation tower, where visitors can view sunrises and sunsets, a blackwater swamp, where visitors can canoe while searching for one of several resident anacondas, and an ox-bow lake that houses a family of giant river otters, which can sometimes be spotted from the dock or boat.
