Amazon Conservation Association
Amazon Conservation Association (ACA) is a 501(c)3 non-profit organization working to conserve the biodiversity of the Amazon Basin through the development of new scientific understanding, sustainable resource management and rational land-use policy.
Founded in 1999 by tropical ecologists Adrian Forsyth and Enrique Ortiz, the organization works in close partnership with the Peruvian nonprofit organization Asociación para la Conservación de la Cuenca Amazónica (ACCA), headquartered in Cuzco, and ACA-Bolivia, headquartered in La Paz. ACA and its sister organizations work by conducting scientific research and establishing partnerships with governments, local communities and other conservation organizations to expand the amount of land protected in the region.
A principal objective of the organization is to develop field research sites ranging from high elevation cloud forest to the lowland Amazon. It is this altitudinal gradient that harbors the greatest known richness of species on the planet. At the ACA field sites university students and researchers are brought to study and observe this diverse ecosystem.
The Brazil Nut Project 
ACA works with castanheiros (Brazil nut harvesters or producers) in the southwestern Amazon to both ensure that local and indigneous populations have a sustainable source of income and provide an incentive to conserve native forests. Land areas that contain castanhais, or Brazil nut forests, range from several hundred to several thousand acres in size and are given in concession (territory) to local families for the nut collecting, also known as extraction. This extractive activity represents more than half the yearly income for thousands of families in these areas, and so far has politically justified the protection of the Brazil nut concession areas for extractive purposes. ACA's program offers technical support to castanheiros, helping them map their trees, redesign extractive trails, and earn more by teaching more efficient gathering techniques.
Through its partner in Peru, La Asociación para la Conservación de la Cuenca Amazoncia (ACCA), ACA has helped to increase the number of Brazil nut producers in the department of Madre de Dios, Peru who have contracts and formal management plans to extract this sustainable resource. In 2006, ACCA assisted 93 small-scale producers gain government approval for Brazil nut extraction in 80,598 acres (326 km2) of forest. The organization worked with these producers to map their stands, develop forest management plans, and win 40-year concession contracts with the Peruvian National Institute for Natural Resources (INRENA). Producers were also trained in sustainable forest management through workshops, meetings, and technical assistance.
Los Amigos Conservation Concession 
In 2000, ACA and its local partner ACCA established the world's first private conservation concession, called Los Amigos ("Friends", in Spanish). The Los Amigos Conservation Concession lies at the mouth of the Los Amigos River and covers approximately 360,000 acres (1,500 km2) of old growth of Amazonian forest in the department of Madre de Dios in southeastern Peru. Here, the organization focuses on sustainable forest management, research activities, conservation education in local schools, and natural resource management training for communities. The Los Amigos Biological Station, commonly known by its Spanish acronym, CICRA (Centro de Investigación y Capacitación Río Los Amigos) sits on a high terrace at the confluence of the Madre de Dios and Los Amigos rivers, contiguous to the Los Amigos Conservation Concession.
In 2005-2007, CICRA was the most active research station in the Amazon Basin, hosting an average of 25 researchers and assistants per day. During the same period, it hosted 145 different research projects addressing animal behavior, biogeochemistry, botany, conservation biology, geology, hydrology, zoology, as well as biological inventories of 25 different taxa, ranging from copepods to marsupials. Most research visitors are associated with universities in Peru or abroad, and many receive funding to visit the station through ACA's and ACCA's grant programs. CICRA is also a leading training site for young Amazonian scientists and conservationists. Between 2002 and 2007, the station hosted 19 field courses, ranging from introductory courses on Amazonia to specialized courses on plant identification, ornithology, and arthropod biology.
Wayqecha Cloud Forest 
The Wayqecha (meaning "friend" in Quechua) Research Center covers 1,450 acres (6 km2) of cloud forest habitat, and serves as an ecological buffer for Peru's Manú National Park. At 3,000 meters above sea level, the Wayqecha Biological Station sponsors research on cloud forest ecology and climate change and species adaptation. ACA offers a competitive grant program for Peruvian students and international researchers that are interested in cloud forest science and conservation.
