Whangarei, Sept 9 - Kiwi numbers in Northland may have dropped 40 percent since 1995, according to Department of Conservation (DOC) research. Annual monitoring at 29 sites in Northland has shown kiwi call counts have dropped an average 10 percent per year since 1995. DOC advisory scientist Ray Pierce said that while kiwi were present at all sites monitored, numbers were down an average 18 percent on last year. While call counts provided an index of kiwi abundance, they also correlated closely with the actual number of birds. Dogs, ferrets, stoats and weasels were being blamed for the decline, which had been noted in all but the most intensely controlled kiwi habitats. Those sites, including Trounson Kauri Park and a bush area north of Whangarei, were showing the high level of management needed to protect the kiwi, Mr Pierce said. "The most important thing members of the public can do for kiwi is to control their dogs in and around known kiwi areas. We are fortunate here in Northland to still be able to hear kiwi in the wild, but everyone has a role to play in safeguarding their future on the mainland," he said. While it was not known exactly how many kiwi survived in Northland, their numbers were several thousand, Mr Pierce said. DOC monitoring involved volunteers and staff listening for two hours after dark for four nights. Northland kiwi call counts remain among the highest in New Zealand. Kiwi dwelling between Whangarei and the Brynderwyn Hills, about 60km south of the city, had been wiped out in the 1970s and 1980s and numbers elsewhere had been rapidly declining since. |
