I've done one safari for plains game in Namibia, and I'm now looking at Tanz, Zim or Moz for my next safari, this time for Cape buffalo. I'm getting conflicting views on the fence situation in the Selous, the Save and Niassa, respectively. I'm pretty sure there aren't any internal fences in the Selous or Save, but there may be a perimeter fence around some or all of these two reserves. Correct? I don't believe there is any fencing around the Niassa. Correct? Thank you in advance.
