This project will use data collected from wild animals, landholder surveys, and computer simulation models to understand why invasive chital deer (Axis axis) are suddenly increasing in number after many years of slow population growth. By combining multiple empirical datasets and developing new modelling techniques, we will generate a new method for understanding population trends in introduced species. The results of this study will allow Queensland Department of Agriculture and Fisheries and others to better predict invasive species growth rates, which will allow for better, and more cost effective control methods.

该项目将使用从野生动物，土地所有者调查和计算机模拟模型收集的数据来了解为什么入侵的赤鹿（Axis轴）在多年的人口缓慢增长后突然增加。通过结合多个经验数据集和开发新的建模技术，我们将产生一种新的方法来了解引进物种的种群趋势。这项研究的结果将使昆士兰州农业和渔业部和其他部门能够更好地预测入侵物种的生长速度，这将允许更好，更具成本效益的控制方法。
