Much has to do with the tough winter of 2011 and afterwards the dry spell of later months. It wiped out almost all of the flora in the whole area, with it the animals that feed on such vegetations were in dire need to look for fod elsewere.

It is more than obvious that along with the animals who feed on this environment also were (are) followed by the animals who prey on them for survival. It is all a matter of moving to the place of food source.
