Although a much smaller feat, New Zealand was very successful in eradicating an estimated 200.000 mice from Antipodes Island without affecting native animals populations [1]
There is an interesting video about the preparatory research leading up to this highly successful pest eradication [2]
Very curious to see how well the Predator Free 2050 program will turn out.
