Abstract: Hendra Virus (HeV) was first identified in 1994 following the outbreak of a new disease which is fatally affecting horses and humans in South-East Queensland. Since, this outbreak, there have been subsequent incidents reported in South-East Queensland. Fruits Bats (Pteropus sp.) commonly known as flying-foxes have been identified as the natural host of the virus. In this study, an in-depth analysis is carried out to determine the correlation between food source vegetation and the flying-foxes roosting sites. This investigation may determine whether clustered or dispersed vegetation has more impact on the incidence. Using spatial analyst tools, the Major Vegetation Subgroups (MVS) present within 20 km buffer range of grey headed flying-foxes and black flying-foxes roosting sites are identified. The identification of abundance of food sources for individual species within their minimum foraging range indicated a strong correlation between their site locations and vegetation subgroups present. A 10 km range vegetation study on the incident locations identified the presence of ‘food sources’ of both species. The clustering of the food resource vegetation present near the incidence was studied using Getis-Ord General G Statistic method which indicated statistically high clustering with 99% confidence level at 3 km distance threshold. The findings suggest that the presence of potential ‘food resource’ of the flying-foxes within certain proximity increases the risk of Hendra virus disease transmission to horses.
