The relationship between seed bank size and stem diameter indicates when management should be conducted.
(A-D) The relationship between the seed bank (m-2) and stem diameter of four ant-dispersed Australian Acacia (Acacia pycnantha, A. saligna, A. mearnsii, A. longifolia). Relationships were estimated by quantile regression at the 95th percentile. (E-H) The average seed bank size (m-2) (+SE) for stem diameter classes of the studied species.
