Distribution of the invasive alien tree Schinus molle in western South Africa

We examined the distribution of the invasive alien tree Schinus molle (Peruvian pepper tree; Anacardiaceae) in South Africa, where it was planted over large areas. Localities of planted and naturalized trees were mapped along 5380 km of roads. A correlative modelling approach was used to produce profiles of present and future environmental conditions characterizing its planted and naturalized ranges. A cellular automata simulation model was used to estimate the dynamics of S. molle under future climates and different management scenarios.
