Data-deficient species

Data-deficient species are threatened species that we need to know more about before we can secure them in the wild.

Small flower grevillea (Grevillea parviflora subsp. parviflora) is a data-deficient species in NSWWe can’t develop a conservation project for more than 150 species because we don’t know enough about them. We need to do more research to find out about:

  • their life history
  • their distribution
  • threats to their survival.

Examples in this category include finger panic grass, small flower grevillea and the little whip snake. Research on these species is a priority for the Saving our Species program.

Current work on these species aims to identify major gaps in our knowledge and set survey and research priorities.

Once we understand more about a data-deficient species, we can move it to another management stream and develop relevant conservation projects for it.

The bilby (Macrotis lagotis) is presumed extinct in NSWPresumed extinct

The data-deficient species stream includes 72 species that we presume are extinct in NSW, such as the bilby.

If a ‘presumed extinct’ species is rediscovered in the wild we look at how we can increase our knowledge about it.

Once we learn more about the species we can potentially develop a conservation project and move it to another management stream.
