Phase portrait of System (2) showing the coexistence of , , . Equilibria and correspond to the removal of the pastoralists with their herd and persistence of forage or water resources. We can observe here the local asymptotic stability of , , and when kgDM/ha and mm. The rest of parameters are in Tables 1 and 2.
