Cool! I did find an article referencing the Prescott area referring to AZGFD moving pigs to new areas but no specifics on actually moving them there. They did a lot of stuff that wasn’t ever publicly documented.
“This boom was aided by the Arizona Game and Fish Department, which transplanted javelinas to some new areas of the state up until the late 1970s in an effort to supply more game animals. But most authorities say the creatures have moved north primarily on their own, and in the process, they have caused trouble for many Arizonans.”
While grassland species continue to lose ground in the Southwest, other animals are taking advantage of the region's changing landscape
