The artists at Mowanjum engage in continued harvesting practices of traditional materials to ensure that vital cultural knowledge is maintained for future generations.

Bush trips that focus on material harvesting, as well as skill and traditional language building, are integral to many contemporary Mowanjum artists practice. These are coordinated alongside elder Ngarinyin, Worrorra and Wunumbal speakers, who help revitalise these ancient creative processes.

In 2015 Mowanjum art workers harvested ornmul (white ochre) with senior Ngarinyin man Alec Unenjen (dec) and traditional owner Heather Wungundin on Ngarinyin country. Ornmul can only be harvested during the dry season when the rivers and creeks are dry.
