What is the economic benefit of giraffes to the government, tourist draw? Regardless they don't have the resources to cover millions of acres of open savannah, enforcement just isn't going to work for this problem.
If the economic benefits of protecting the giraffes outweigh the economic benefits of hunting them, then the resources for enforcement do exist. It's "just" a matter of distributing the benefits effectively.
There isn't just endless savannah. Poachers need local infrastructure, supplies, protection, etc. If locals can make a living from tourism and from protecting the animals, they will stop the poachers and/or stop being poachers.
