In 2003, Terralingua developed the first educational booklet on Biocultural Diversity, in collaboration with UNESCO [REF] Sharing a World of Difference: The Earth's Linguistic, Cultural, and Biological Diversity, along with the companion map, The World's Biocultural Diversity: People, Languages, and Ecosystems (UNESCO, 2003).
In 2008, in collaboration with IUCN and the American Museum of Natural History (AMNH), Terralingua co-organized a major follow-up symposium on Biocultural Diversity, "Sustaining Cultural and Biological Diversity in a Rapidly Changing World: Lessons for Public Policy", which was held at the AMNH headquarters in New York City.
