Aim
We develop a framework for quantifying invasions based on lagged trends in invasions (‘invasion debt’) with the aim of identifying appropriate metrics to quantify delayed responses at different invasion stages – from introduction to when environmental impacts occur.
Location
World‐wide; detailed case study in South Africa.
Methods
We define four components of invasion debt: the number of...
