Modelling Acacia saligna invasion in a large Mediterranean island using PAB factors: A tool for implementing the European legislation on invasive species

•SDM is an effective tool for predicting plant invasions.•An integrative PAB approach to explain Acacia saligna distribution in Sardinia.•Combined action of propagule pressure, abiotic, biotic factors promotes the invasion.•iSDM largely benefits from the use of high resolution and dedicated thematic layers.•iSDM is an effective tool for decision-making to prevent the invasion risk.
