Australia has only one top order predator, the dingo.

Australia has only one Top Order Predator, the dingo and the only threat to the dingo is human persecution. Dingoes have no enforced legal protection anywhere. Dingoes help promote native-exotic coexistence. When we mess with the dingo the effects we are having on the ecosystem is massive. With the dingo barrier fence, on the northern side is to keep them out from the southern side, where sheep production exists. There are two ecological universes. Inside the fence dingoes are persecuted severely and that is where the population of foxes are highest and small mammal extinction rates are highest, with poorer and less vegetation. If you can get a place to leave dingoes alone the effects that they have are almost immediate and powerful. Dingoes recover, cats, foxes and herbivores decline and small native mammals increase. We need to allow dingoes to recover, to naturally suppress their prey and suppress smaller predators, which is what predators do and to allow native species to recover. What would Australia look like today if we weren't waging the war on dingoes for the last 200 years? Lethal control disrupts social structure. Dingoes are like us and social creatures. Dingoes actually perform family planning. If we leave them alone they don't all breed, they perform complex social structures. In a stable pack they have one pair that reproduces. If another female should mate, then that pup gets killed, mostly, by the Alpha female. Now if we kill the alpha female then all other females will mate and produce. Then there are no laws within that pack and it's not natural for them. This is why we need to leave them alone to function as they should. Coexistence with predators is good for livestock. There is evidence of this all over the world and as an example in South Africa, 11 farms stopped killing predators. Some used guardian dogs, some shepherds or whatever that had to do. Within 2 years the loses they had to predators went down 70% and the costs of killing predators went down 70%.
