Due to extinction debt, the future extinction of this shrub is nearly guaranteed. The local extinction of several species of pollinating birds in 1870 has caused a long-term reduction in the reproduction of the shrub species, which requires these birds to produce seeds. However, as the plant is slow-growing and long-lived, its populations persist.
