Tanzania has three classes of hunting licenses. A hunter must choose a ten-day, sixteen-day, or twenty-one-day license, and a larger variety of species are available on the longer licenses. For example, a hunter may hunt up to two buffalo and a variety of plains game on a ten-day license, but must buy a sixteen-day license to hunt crocodiles and waterbuck and a twenty-one-day license to hunt elephant, sable, roan, lion, leopard, oryx, greater kudu, and eland. In addition to the license fee, trophy fees are charged for each species taken, as well as other government fees, which can add significantly to the safari cost.
