Which Apes or Monkeys do not Live in Forests or Jungles and live on the Ground?

Baboons are adapted to living on solid ground.

They generally avoid forests, spend little time in trees, and are most comfortable traveling in herds on open land.

Gorillas are also ground dwelling apes and do not hang out or live in the trees.

Another great ape species, the Orangutan, spends more time on the ground than most tree dwelling monkeys.

One possible reason for this behavior is that a lot of food can be found on the floor of the forest. Fallen fruits from trees can be yummy if it has not yet gone bad.

For larger apes, traveling on the ground is usually the faster way to go, as opposed to jumping from tree to tree.
