Again, I'm not going engage with the mindless hateful posts, but there are a couple of things worth noting:
1: If this operation is successful, possums will be eradicated from that block. ZIP have successfully eradicated possums entirely from a smaller area last year down near Haast, there is a good chance that they will succeed here. The Whataroa/Perth only receives 1080 for possum control (every so often when monitoring shows high numbers). If possums are eradicated, it will never be 1080'd again. That's a win for everyone, surely.
2: Kea already eat dead tahr, and there is no shortage of dead tahr in the Whataroa/Perth tops. A few more carcasses dropped up there will not train them to do anything new.
