Wellington’s wildlife continues to thrive as a result of sustained predator control efforts across the cities reserves
and backyards.
A recent report commissioned by Wellington City Council has found significant increases in the number of species of
native birds found in the network of reserves throughout our eco-city.
The Council has engaged a team of professional ecologists to record birds for five-minutes at 100 permanent
count-stations across Wellington city reserves since in 2011. The annual counts provide a high-level picture of how
native birds are doing by monitoring the trends in diversity, abundance and distribution.
Since 2011 there has been a substantial increase in the proportion of bird species ranked as Nationally Threatened or
‘At Risk’ in Wellington City. There has also been a significant increase in the average number of native forest bird
species encountered during the survey, which has been driven by significant increases in five endemic bird species,
namely: tūī, kākā, kereru, tieke and kakariki.
These results show that the populations of native forest birds in Zealandia, together with the increasing levels of
predator control being carried out in parks, reserves and suburban areas throughout the city, are creating improved
opportunities for local residents and visitors to encounter a wider range of New Zealand’s native forest bird species in
the heart of New Zealand’s capital city.
Michelle Frank, Council’s Manager of Urban Ecology Team, is excited by the return of birds to our city. “We want to
congratulate our volunteers and partners for all the hard work trapping predators, planting trees and controlling weeds
in recent years. We are so lucky to be witnessing the return of these manu taonga to our city.
“Wellington is one of the few cities which is seeing nature return worldwide. We are bucking the trend globally, as
across the world biodiversity is generally declining,” adds Michelle.
James Willcocks, Predator Free Wellington Project Manager says “These results support what we are hearing from our
community. We are getting more and more reports of people noticing native birds at their place. People are stoked when
they see the first piwaiwaka in their garden or see falcon soaring above, my favourite is when people see gecko in their
letterbox. Local kids are getting to experience these incredible native species where they live and learn. This is
something we could only have dreamed of just a few years ago. It’s really fantastic that we are able to measure a
significant improvement in the city’s wildlife. To me this report shows that the ecological health of the city is
rebounding and the community effort is making a big difference.”
What you can do to help
• Make a difference at home by planting natives and removing invasive weeds. More ideas at www.wcc.govt.nz/backyardbiodiversity
• Join a local trapping group to trap predators at home and your local reserve https://www.pfw.org.nz/get-involved/
• Connect with your local reserve by volunteering with a local restoration group on NatureSpace https://www.naturespace.org.nz/groups?field_group_region_tid=18_ecosystem_tid=All
• Get involved with the Great Kereru Count which starts Saturday 21 Sept https://www.greatkererucount.nz/
• Record observations of birds you see on www.inaturalist.nz or www.ebird.org - particulary birds like ruru/morepork
Summary of findings
• Tūī are now common and widespread in Wellington City, and were recorded from the majority of five-minute bird count
stations each year. Tūī (endemic to NZ) are now the most common native bird in Wellington. Tūī are now overtaking the
silvereye/tauhou (a native which also occurs in Australia). When visiting a reserve, it is more than twice as likely to
see tūī now than in 2011.
• The chance to see kākā, kereru and tieke in the cities reserves has roughly trebled since 2011.
• Kākā are now commonly encountered in central Wellington, particularly in the suburbs of Karori, Wadestown, Ngaio,
Kelburn, Te Aro and Brooklyn. They are also continuing to extend their range into more northern suburbs such as
Johnsonville, and more eastern suburbs such as Miramar.
• Kererū encounter rates are highest in reserves containing original native forest habitat, such as Otari-Wilton Bush
and Khandallah Park, but they are also frequently observed in adjacent suburban areas.
• Tieke are largely restricted to Zealandia and to forested reserves less than 1-2 km from Zealandia’s pest-proof
boundary fence, so this increase in encounter rates is likely to be a result of ongoing improvements in the mammalian
predator control being carried out in forested reserves adjacent to Zealandia.
• Beyond Zealandia, red-crowned kakariki are now established in Wright’s Hill reserve, Otari-Wilton Bush and Khandallah
Park, Huntleigh Park and possibly also the Wellington Botanic Gardens. Kakariki are sparsely distributed throughout
Wellington City, in both native forest and suburban habitats. The likelihood of encountering kakariki has increased more
than ten times since 2011.
• Whiteheads are largely restricted to Zealandia and to forest reserves within 1-2 km of Zealandia’s boundary fence,
however they may also have recently colonised Trelissick Park and Prince of Wales Park.
• Toutouwai/NI robins are largely restricted to Zealandia and to native forest habitats within 1-2 km of Zealandia’s
pest-proof boundary fence.
• Pick up a native plant from Otari-Wilton Bush Open Day this Saturday 21 September.
These are preliminary findings. Copies of the full report will be available on our website soon.
