Titre : The sheep must give way to the dingo in Australia’s arid rangelands

Western Australian pastoralist David Pollock argues much needs to be learned about how to transition Australia’s vast, arid rangelands pastures from their present, significantly degraded condition to become truly sustainable farming operations.

Présentation
Overgrazing has been the overwhelming cause of the declining condition of our rangelands, yet domestic stock have contributed to less than half the total impact. Unmanaged animals such as rabbits, wild goats and kangaroos ramp up the grazing pressure, leading to a "set stocking" approach to pastoralism, a constant competition over scarce resources at the expense of plant and animal biodiversity.

Any responsible grazing system must allow the most palatable plants time to recover through a rotational grazing system, which is unworkable when so many unmanaged animals continue to graze pastures vacated by stock. Pastoralist David Pollock recommends that hardest of all things—a cultural shift.
