The U.S. Department of Agriculture has completed an effort to eradicate feral swine regarded as troublesome and dangerous in a federal wildlife refuge along the Colorado River.
Today's News Herald reported Tuesday that part of the Havasu National Wildlife Refuge was closed last month while USDA agents shot the animals from a helicopter.
U.S. Fish and Wildlife Service spokeswoman Beth Ullenberg says the agents eradicated nearly 70 feral swine.
The non-native pigs carry diseases and damage habitat and property.
The hunt had initially been expected to last two weeks but it took less than four days.
The USDA will continue to work with wildlife refuge staff to monitor the area for hog activity.
Officials have said the carcasses will be buried.
