Indigenous songs are an important resource for ecological information. Songs of the Warlpiri people in Yuendumu, Australia, convey information about wild edible seeds, and the songs of the Sakha people in Siberia, Russia, address the effects of climate change on local ecosystems. There have been efforts made to preserve Indigenous languages over the years-e.g., the United Nations' International Decade of Indigenous Languages (2022-2032). However, such attempts have typically focused on spoken language despite the fact that some expressions in these languages appear only in songs. Therefore, if those involved in such efforts want to ensure that a comprehensive range of information is secured, they must

recognize that Indigenous languages likely have more unique expressions that represent ecological knowledge than represent other types of information.

acknowledge that Indigenous songs are largely but not entirely composed using phrases taken from spoken language.

incorporate the preservation of songs into their broader efforts to protect Indigenous languages.

analyze musical similarities in the songs of the Warlpiri and Sakha people.
