LAKE HAVASU, Ariz. (AP) - Wildlife managers with the U.S. Department of Agriculture are keeping a close eye on the wild hog population in Arizona.
Millions of wild hogs are making their mark across the country, and the Arizona director for the USDA's Wildlife Services division says the last thing he wants to see is a damaging invasive species establish itself in Arizona.
Director David Bergman says wild hogs root up wetlands, damage agriculture crops, threaten endangered species and spread diseases to commercial livestock.
National feral swine expert Jack Mayer says there are estimated to be between 500 and 1,000 wild hogs in Arizona.
The wild swine have been spotted in Cochise, Pima and Yavapai counties. The biggest cluster is in the Lake Havasu National Wildlife Refuge in La Paz County.
