Summary

This project collects baseline information on faunal biodiversity from the experimental sites of Dr Peter O'Reagain (DPI, Charters Towers). Dr O'Reagain's project, based at the cattle station Wambiana, was established to investigate the relationship between pastoral stocking rates, rainfall variability and land condition. These sites comprise two replicates of each of five grazing regimes (each in 100 ha paddocks).

To examine the relationships between the experimental regimes and how biodiversity responds, it is important that information is collected before the influence of the treatments begin. This is in order to examine whether there are pre-existing differences in biodiversity between the plots, and to provide a benchmark from which to assess subsequent divergence.

Outputs

This data will be used subsequently to:

  • Assess the impacts upon biodiversity from a range of pastoral regimes.
  • Provide information which will contribute immediately to the TS-CRC-supported PhD research project by Alex Kutt on conservation values of the Desert Uplands bioregion.
  • Provide baseline information on vertebrates and invertebrates for all plots established for experiment assessing impacts of a range of pastoral regimes.
  • Provide biogeographic information on fauna for use in Desert Uplands studies.

Progress

Baseline information was collected in 1998 and 1999 by Ben Hoffman (invertebrates) and Alex Kutt (vertebrates). This data will allow responses of biodiversity to the grazing regimes to be determined, following a sufficient period of implementation of those regimes.

The grazing trial site will be re-sampled in two to three years to assess and document trends in biodiversity responses to the different grazing regimes. Such biodiversity responses will be included in the range of other responses (vegetation, soils, production, etc.) already being monitored by Queensland Department of Primary Industries, in order to derive a holistic and integrated overview of the costs and benefits of different grazing practices.
