Abstract

We consider a two-dimensional continuous model that describes the ecology of Easter Island. We show that the increase of the parameter corresponding to the diffusion of trees on the island has a stabilizing effect on the system, potentially preventing the collapse of island’s ecology. Next we give analytic proofs for these statements, and conduct numerical experiments that confirm these results.
