In fragmented landscapes, wildlife need to move between habitat patches to exchange genes, increase the size of declining populations and recolonise areas were animals have become extinct. For many species, roads may act as barriers that prevent or limit dispersal, potentially isolating some habitats. In this study, we aim to quantify the extent to which major highways in regional Australia form a barrier to the movement of mammals and invertebrates. We will then test the effectiveness of measures that may facilitate safe crossing by measuring their rate of use, reduction in road kill and increase in population viability. This information can then be used to construct major roads that are more environmentally sustainable.

在支离破碎的景观中，野生动物需要在栖息地之间移动以交换基因，增加下降的种群规模，并扩大动物灭绝的地区。 对于许多物种来说，道路可能会成为阻止或限制扩散的障碍，可能会隔离一些栖息地。 在这项研究中，我们的目标是量化的程度，主要公路在澳大利亚地区形成的障碍，哺乳动物和无脊椎动物的运动。 然后，我们将通过测量其使用率、减少道路死亡和增加人口生存能力来测试可能促进安全过境的措施的有效性。 这些信息可以用来建造环境上更可持续的主要道路。
