In a resilient framework, alternative stable states lead to hysteretic state whereby the reverse path is not the same as the forward path. Within a range of conditions, humans can maintain the stability of the ecological system. Increasing human pressure beyond a critical point (bend in the curve) will lead to a sudden collapse of the ecosystem. In order for the hysteretic state to return to its previous point, human pressure needs to be reduced to a lower level (horizontal arrow) such that the resource increase again (vertical arrow point). Filled circles indicate stable points in the ecosystem, while opaque circles indicate unstable point.
