Angas Downs is part of the homeland of southern Luritja and northern Yankunytjatjara people. Together they are called Matutjara, and speak a dialect that is a mix of the two languages. The people living at Imaṉpa include Luritja, Yankunytjatjara and Pitjantjatjara. The property contains several places (songlines and sacred sites) that are important to native families' "Tjukurpa". Several animals that live in the reserve represent ancestral totems, reminders of people's identity, kinship and descent. Many of the plants and animals have also been important sources of food for the locals for thousands of years.
