摘要

为了检验哺乳动物病虫害防治的长期效果，将2008-2020年在普雷奥拉森林公园南怀帕帕生态区内(WEA)的北岛kākā (Nestor meridionalis septentrionalis)密度的年度距离抽样估计值与2000-2007年在同一地点和同一时间(10月)发表的估计值进行了比较。Kākā密度从2000年至2007年的平均0.0.5 (95% CI 0.5 - 0.6)只/公顷增加到2020年的0.2.3 (95% CI 1.9-2.8)只/公顷，增加了约4倍。2000年至2018年的平均增长率为每年6.9%。Kākā恢复可能是多重事件和长期(大约20年)，大规模，频繁，有效控制负鼠(Trichosurus vulpecula)和可能的鼬鼠的功能。建议继续进行目前的虫害防治以及kākā和虫害监测。

Recovery of North Island kākā (Nestor meridionalis septentrionalis) within Pureora Forest Park, 2000–2020

: To test the long-term efficacy of mammalian pest control, annual distance sampling estimates of the density of North Island kākā ( Nestor meridionalis septentrionalis ) within the southern Waipapa Ecological Area (WEA), Pureora Forest Park from 2008–2020 are compared to previously published estimates made at the same sites and time of year (October) between 2000–2007. Kākā density increased approximately four-fold from an average of c. 0.5 (95% CI 0.5–0.6) birds ha −1 between 2000 and 2007 to c. 2.3 (95% CI 1.9–2.8) birds ha −1 in 2020. The average of rate of increase between 2000 and 2018 was c. 6.9% per annum. Kākā recovery is likely to be a function of multiple mast events and long-term (> 20 years), large-scale, frequent, effective control of possums ( Trichosurus vulpecula ) and probably mustelids. It is recommended that the current pest control as well as kākā and pest monitoring continue.
