Good areas for leopard is towards the Forestry area to the north/north west(Towards Kazuma Pan). Far to drive but good areas. On the way you will cross sand forest, Miombo and teak wood areas, you will clearly see these while driving through. Excellent areas to check for tracks and activity. Contrary to popular belief, these are good areas to place bait almost in the track as apposed to a ways off into the bush.
Area towards Unit 3 not so good but always check for tracks of large males patrolling through area. If found, follow the direction and bait well ahead.
Make sure water is not to far away from bait sight. Minimum blind distance would be 35 meters.
Good luck.
