people have been catching and killing burmese for YEARS, and that number is whats recorded by researchers in mostly the ENP and a few waterways. I know the number is probably double that over the years for animals people have caught/ killed/ that have no idea of anything going on but are avid fishermen,hunters,bird watchers,and happen to stumble upon them. They do not report such things, they just kill them or catch them. I thinkwith predators(which they have many), people finding them by chance, cars, lawnmowers, hunters, fishermen, hobbyists, snake hunters(as by catch),and others that the numbers are pretty well in check.
