What can be done to make Gila National Forest a protected land, especially from ranchers and hunters?

This is one of the oldest and biggest public land in the United States. Could you imagine if it was a park that protected all of its historical & endangered natural species? For example, jaguar, cougar, Mexican wolf, brown bear, bobcat and coyote all belong here before being wiped out for cattle industry, which can graze all year round (makes unbalance land for nature). The protected land would eventually be transformed to its most beautiful state as before. Tourism would blossom because it would attract so many people around the world like African & India Safari. The reason, similar weather, it's own unique wildlife and it would hold over 5 large predators in one area similar to African wildlife.
