active burrows. By comparing the types of predator, and frequency of visitation to burrows in declining versus healthy Tjakura populations we could investigate the relationship between predator composition and abundance and the status of Tjakura populations. Results of this study could inform experimental predator control manipulations.

 Introduced herbivores – can Tjakura coexist with introduced herbivores such as cattle, camels and horses? Do we need to make sure no stock are introduced to sites supporting Tjakura populations,
 or is there a certain low stocking rate they can tolerate? Is it still worth surveying areas around the edge of the range where there is a history of grazing impacts?

 Interactions with other species – Are interactions between Tjakura and woma pythons, and Tjakura and mulgara positive, negative or neutral? Are these
 uncommon native prey more abundant where they can take refuge in Tjakura burrows (or are goanna burrows just as good), and do mulgara, womas and goannas enter Tjakura burrows for shelter or to eat Tjakura?

 Relatedness - A current study aims to use genetic data obtained from Tjakura scats to determine abundance of animals in a burrow and relatedness of individuals between burrows and sites. If successful this genetics study could be expanded across the range of the Tjakura to examine whether there is connectivity between sites, how many subpopulations exist and whether some of the small subpopulations are suffering from inbreeding.
