I thought you guys had wild dogs, don't they gang up and eat some of that stuff? You need to import a few hundred Canadian and Alaskan wolves. They know how to eat up and would chow down on about all of your critters. Those donkeys, pigs and goats would go first. I am sure they could handle the young camels and would be more then happy to kill any thing they can chew on.
Get some Honey Badgers for the toads and snakes. They are a fascinating critter to me.
The heat would probably do the wolves in though.............
