Certainly an immensely challenging task, but hopefully not impossible. We have hardly begun to apply new technology to the problem - drones, new lures, mesh networks, low cost cameras.

Also we've stopped those pesky Victorians from introducing new species. Its a good thing they never introduced wildcats to control the stoats, weasels and ferrets - which they introduced to control the rabbits - which they introduced to give them something to shoot at on quiet Sunday afternnons.
