For a good number of years now various people/agencies have talked about using a contraceptive approach to the NZ possum problem. Yet nothing seems to have happened. Still we see millions of dollars spent on 1080 drops. The UK has taken action to eradicate grey squirrels and "The government scientists leading the research say the contraceptive, which makes both male and female grey squirrels infertile, should be ready to deploy in the wild within two years." https://www.bbc.com/news/science-environment-62096272
WTF is the NZ government thinking in their persistent use of poison that is indiscriminate when the money could have (and still could be) spent on a contraceptive programme.
