 movement of livestock herds ever closer to these wildlife areas kind of hems the lions in. And so in this particular reserve, there's really not a lot of room for maneuver. So for those lions to get over to where there were females, they really had no choice but to swim across. Now, another possibility might have been there is a land bridge or a footbridge that goes across there, but that's so frequently used by people. And lions will always avoid where there are people if they can.
