Assess the Viability of Aerial Baiting for Dingoes in South West Queensland Using GIS Based Weighted Linear Combination Modelling

Harris, Matthew (2017) Assess the Viability of Aerial Baiting for Dingoes in South West Queensland Using GIS Based Weighted Linear Combination Modelling. [USQ Project]


Dingoes (Canis lupus dingo), wild-dogs (Canis lupus familiaris) and dingo-dog hybrids (Canis lupus dingo X Canis lupus familiaris) have severe negative impacts within the agricultural sectors here within Australia, particularly within cattle and sheep farming industries here in Queensland. With numerous management strategies already enforced by governments, it is noticeable that these strategies need to be more effectively planned and managed to reduce the ongoing implications dingoes cause. Thus, the aim of this project was to determine a thorough understanding of the relationship between movement patterns and seasonal variations within a number of different dingoes within the southwestern region of Charleville and Morven, 660 kilometres west of Brisbane. Utilising the GPS locations of these animals, in conjunction with a vast number of different land attributes, a weighted linear combination model was created in GIS to create a site suitability map to outline key areas that would be highly suitable to conduct an aerial baiting program over the proposed study site.

The results of this analysis found that over the entire study site, about 85,455 ha were highly suitable for aerial baiting. In addition to this, it was found that 172, 027 ha were moderately suitable and 106, 588 ha were unsuitable for aerial baiting to occur. The areas of high suitability were noticed to be approximately 1 to 2 kilometres in width, creating corridors around the road networks and drainage features within the area. The density of the dingo GPS locations throughout the site established this fact, with 85% of the locations being within the highly suitable areas. This was due to the fact that males tend to highly frequent these areas during the autumn months when mating, and females use them minimally, as they recognise them as territory boundaries. It was concluded that utilising GIS to establish a site suitability analysis for the effective planning of an aerial baiting program to be conducted over a specified study area can be completed accurately and effectively, and that the same method can be applied to other strategies and other disciplines within the same area of feral animal management.
