Newhaven Wildlife Sanctuary population (Eco Logical Australia 2018).

 Other large populations, known to comprise more than 100 burrows, occur on Newhaven Wildlife Sanctuary, UKTNP (and the adjacent Yulara Freehold Land and Katiti-Petermann IPA), and on the Kiwirrkurra IPA.

 A study of the genetic diversity of Tjakura across its range revealed that sufficient similarity occurred between Newhaven Wildlife Sanctuary and Sangsters Bore subpopulations to infer historical connectivity;

 Watarru, Docker River and Warburton animals were also grouped, but the Uluru population was genetically distinct, leading scientists to believe it has been cut off from western sites for at least 350,000 years (Dennison et al. 2015). There has been no genetic analysis of any of the other Western Australian subpopulations.
