Situation analysis report: current state of scientific knowledge on kangaroos in the environment, including ecological and economic impact and effect of culling

The most significant publications since the last review of the literature in 2000 are those on the sophisticated models that have been developed based on harvesting statistics. These are providing insight into demographics, genetics, movements, and significant harvest refugia, as well as sustainability of the harvest and prediction of the likely effects of management variations and stochastic events. They offer the possibility of more cost-effective management through optimisation of monitoring.

A second significant development is the revision of the Dry Sheep Equivalent (DSE) for
kangaroos, which suggests that previous estimates were as much as three times too high. Confirmation of this is critical to understanding kangaroo grazing impacts and interactions. DSEs should also be calculated separately for all four harvested species.

Areas of research need that were gleaned from the literature include: kangaroo land
degradation impacts and effects on wool production; confirming the lower DSE estimate in free-ranging animals; and greater understanding of kangaroo movements. Knowledge of demographics has improved but is still in its infancy. Improved knowledge in these fields has potential to improve the predictive models.
