Kokako population numbers in Hunua Range after 1080 aerial poisoning

Tracy Jane made this Official Information request to Department of Conservation

This request has an unknown status. We're waiting for Tracy Jane to read recent responses and update the status.

From: Tracy Jane

Dear Department of Conservation,

Please provide me with the information
1) about the number of kokako that have been moved from a breeding facility to the Hunua Range after 1080 aerial poisoning. This pertains particularly to the most recent poison operation last year, but if there have been other times that kokako have been moved from one rohe to the Hunua Range after other drops, please include those in this information request.
2) In addition, could you please point me where I would find the current numbers of rat and mice and stoat populations in the Hunua Range, as I have read research that although rat populations drop to nearly zero post-poison operation, they do increase dramatically around a year after an operation without adequate ground operations.

3) In addition, could you please explain DoC and Auckland Council rational of why the Hunua Range, being easily traversed terrain and so close to a large population, was poisoned instead of using ground control management of pest species. And please explain the cost comparison between the aerial poison operation and what it would cost if a land-based pest management system, and if DoC/Council had put that to public tender?

4) In addition, could you please tell me, if any, what post-1080 poison operation ecological testing DOC and Auckland Council have carried out on the Hunua Range that pertains to invertebrate numbers and health, soil health - including worms, soil fungi and bacteria, fluoride concentrations in the soil, leaf litter decomposition, and so on. (thinking about how the "Wood Wide Web" would be affected such as this https://www.sciencemag.org/news/2019/05/...)

Yours faithfully,
Tracy Livingston
