Although still possible, there is presently no documentation supporting wildlife moving due west of Wami Mbiki.
There are signs of elephant and buffalo moving in this direction from Mikumi NP, with elephants raiding small farms. Moreover there is potential for animal movement along the right/east side of the Mkata river.
Use of the Mkata River, either in the riverbed itself or along its banks, is a good way for animals to travel with plenty of cover.
The 600,000 ha Mkata Ranch situated at the Mikumi end of the Mikumi-Wami corridor is owned by the government but has recently been subdivided and leased to locals to farm cattle. One of the conditions is that the locals fence their land (using poles and wire); this will impede large mammal movement.
However only the western side of the Mkata Ranch is leased (on the western side of the Mkata river) and the east side, while still being a government owned cattle ranch, is not fenced and is open for movement of animals.
The WMA to the east of the ranch and north east of MNP may still be a viable route for animals to move between the north east section of the park, the WMA, and the Wami WMA, but nearby villages and a highway may mean that the area is easily accessed by people.
