Guardian emus eat locusts, kill foxes on Portland raspberry farm — and make cuddly petsCraig Woods was once a fitter-and-turner, but eight years ago he gave it away for a life of hard yakka under the open sky, setting up a chemical-free raspberry farm where he and wife Melissa grow most of their own food and run on solar power and tank water.The Woodses encourage a rich, biodiverse food web on their acreage, using compost from their pig Boris and their chickens to fertilise their berries, mowing their lawns with guinea pigs, and relying upon native wrens to pick off grubs on their raspberries.The most vivid example of this animosity is the emu-proof fence that protects West Australian wheat farmers from the trampling feet of huge mobs of migrating emus in search of food and water.The emu war made some impact, but subsequent emu-culling bounties in 1934 proved to be more efficient.In comparison with the huge numbers of wild emus that can destroy crops, the handful of domesticated emus on Mr Woods' farm behave like a guardian species that he says can be imprinted on a mob of cattle, sheep or chickens."
