A new report analysing the 2014 kiwi call data for the Kiwi Coast confirms that kiwi are on the increase in eastern Northland.
The report analyses data collected at 73 sites along the Kiwi Coast, predominantly by volunteers, during last years Northland Kiwi Call Count Survey.
Some kiwi listening sites have now recorded over 10 years of data, allowing scientific analysis to be carried out, and population trends to be determined. The Department of Conservation’s Northland Kiwi Call Count Report 2014 found that while kiwi are still declining in some parts of Northland, overall kiwi are on the increase along the Kiwi Coast:
The overall trend (in eastern Northland) since 1995 is a statistically significant positive linear trend of increasing mean call rates (Hilary and Topia, 2014. Northland Kiwi Call Count Report for 2014).
This overall trend was analysed at greater depth in the 2014 Kiwi Coast Kiwi Call Count Report, to investigate kiwi call rates in specific areas where predator trapping and good dog control is in place.
At this finer scale, the data showed that kiwi are increasing at almost all projects areas along the Kiwi Coast.
