Maybe the Opuntia was introduced. I suppose the answer is published somewhere, I don't know. But that would be strange in that place, 60 km inland, in an arid region where there was no agricultural business---no one ever sold any plant food from there--it was so far inland,
so hot and dry. Yes, just the right place for Opuntia, true. The persons who might have had that answer are no longer living. Strangely, I am outliving all these people. But the cactus just took over. It was everywhere, before the importation of that insect. That made it hard
for the natives who counted on cactus to feed the cattle.
