In Australia, the Australian plague locust has recently become a more prevalent crop pest. Interestingly, this locust has been found to avoid tree patches. This suggests that trees may play a role in keeping locust populations at bay, however deforestation since colonial establishment has cleared all but 33% of these natural tree patches. In this study, we begin to investigate how and why the Australian plague locust abundance changes on a tree patch to grassland gradient.
