Data on this site are derived from a variety of public government and non-government sources.

Biodiversity maps are derived from species range data distributed by NatureServe, the IUCN Global Mammal Assessment, and the IUCN Global Amphibian Assessment. Current maps use version 3.0 data for birds, the initial version for mammals, and the November 2008 version for amphibians.

Oil block maps were derived from online data available at Colombia's Agencia Nacional de Hidrocarburos, Ecuador's Ministerio de Minas y Petróleos, Peru's Perupetro and Ministerio de Energía y Minas, Bolivia's Ministerio de Hidrocarburos y Energía, and Brazil's Agência Nacional do Petróleo, Gás Natural e Biocombustíveis.

Protected areas boundaries are primarily from the World Database on Protected Areas (WDPA). For some countries, additional protected areas were digitized from within country sources, including the Instituto Nacional de Recursos Naturales in Peru.
