Biological invasion poses a major conservation threat and is occurring at an unprecedented rate. If we are to minimise invasions, limit their success and mitigate their impact, we need a better understanding of the mechanisms that encourage—and enable prediction of invasion.
This report presents a method for characterising and predicting ecosystem invasibility at the landscape scale using spatially referenced historical data on the locations of non-native plant species. To our knowledge, this is the first multi-species model based on occupancy and abundance data that can be used to predict habitat invasibility.
