Wildlife Services, the Montana Invasive Species Council, the National Feral Swine Program and the Montana Fish, Wildlife and Parks department say the pigs could cause significant damage.
“Multiple people say that if we were to design an invasive species that would do the most widespread damage, feral swine aren’t too far off from being the perfect specimen,” Dale Nolte, of the U.S. Department of Agriculture’s National Feral Swine Program, told the Daily Inter Lake. “It would be a disaster.”
The pigs were described as “rototillers” — they root for food and wallow in farms, fields and forests, leaving terrain unrecognizable. Tahnee Szymanski, of the Montana Department of Livestock, told the publication the feral hogs “can decimate the rangeland by tearing up everything.”
The pigs might also spread diseases impacting livestock and other animals.
