Wild hogs are often trapped and released into new areas by misguided hog hunters. That is how the German boar/feral hog strain began in California. Hell, they brought a whole boat load of Black Forest boar over and turned them loose in the 1920’s. The hogs are not big time migrators unless there is no food at all. I dont think they understand the depth of their problem.
