Currently, Sitatunga are not on quota anywhere in Namibia. They are indigenous to the Caprivi area. Red Lechwe are also indigenous to the Caprivi, but, alas they aren't on quota either, although they are available on a couple of game ranches. Jan Oelofse was trying to build up a huntable herd of them the last time I hunted with him about 4 years ago.
