That's a very interesting post @Sangeeta
and I look forward to Part 2.
Personally I wish it wasn't posted on Page 2 of this thread. Of course people have an idea about all this, even me (which of course is why I supported your announcement of the dreaded petition) but I personally would like to see this posted in the open. It's kind of insulated here by a layer of bunny warmth on page 1 and I am not sure all of those who could learn something from it would ever see it. Also, although Internet discussion is often unappetizing it would actually add a kind of "peer review" to this. But perhaps it has already had a sort of peer review in various posts in the past? Fair enough, if so.
One immediate thought. While the map of lion killings is damning, there is surely a natural tendency for wildlife and therefore lions to be drawn to the river. As a lion it is where I would go to hunt. It is also likely to be prettier and have fewer tsetses than the areas away from the river, so more attractive to hunters and even trackers all else being equal, It would be very interesting to see a breakdown of lion sightings in the national park too, at least from a couple of camps, to show that the lion killing sites are not simply where the lions tend to be, on both sides of the river. Collared lion tracking data would likely offer an even better demonstration. I also imagine that lions tend to cross the river at certain times of year, when water levels are low? Is that true and if so have you checked that the killings occurred at times of year when lions would cross?
Also if you are going to share this more widely, regardless of personal opinion you might want to add an explanation of why, theoretically, GMAs are generally agreed to be a decent idea and why hunting has historically been seen as the only way to sustain the GMAs. It might take any discussion (actual or just in someone's head) straight to the issue at hand rather than getting tied up in whether hunting in the GMAs is good for conservation.
But that's just me!
Great work Sangeeta and anonymous conspirators. Much respect to you for the effort.
