The first of its type in the world, the Threatened Species Index (TSX) provides reliable and robust measures of changes in the relative abundance of Australia’s threatened and near-threatened species at national, state and regional levels.
The TSX can assist policy makers, conservation managers and the public to understand how some of the population trends across Australia’s threatened species are changing over time. It will inform policy and investment decisions, and enable coherent and transparent reporting on relative changes in threatened species numbers at national, state and regional levels. The method by which Australia’s TSX has been created is based on the Living Planet Index, a method developed by World Wildlife Fund and the Zoological Society of London.
