Pennsylvania-Australia collaboration focuses on controlling wild hogs
September 10, 2013
According to the latest estimates, Australia has more wild hogs than human beings, perhaps more than 23 million. No one is certain how many wild hogs roam Pennsylvania -- mostly escapees from commercial hog-hunting preserves and their offspring. But both commonwealths need to control and perhaps eliminate feral pigs, which are a highly destructive species, according to Theodore Alter, professor of agricultural, environmental and regional economics in Penn State's College of Agricultural Sciences.
