Listen to the last episode:
Since 2018 there's been a massive effort underway to clear over 110,000 hectares of South Westland of possums, rats and stoats. As the pest numbers have dropped the native flora and fauna seem to have flourished. The eradication stage is now nearing completion, and the focus is switching to maintenance. What will it take to keep the pests out long-term? And what can be learned from this large-scale project that could be used elsewhere in Aotearoa?
