Modelling alternative management strategies of invasive tree species at the expansion front: Ligustrum lucidum as a case study

Ecological Solutions and Evidence, Volume 6, Issue 1, January–March 2025.
The management of invasive non‐native species is a global challenge, particularly for long‐lived trees. Individual‐based models (IBMs) and expert knowledge are valuable tools for evaluating different strategies to control the population dynamics and range expansion of invasive species.
