Helen on a recent visit to Manawa Karioi.
What is your background, and what inspired you to start Virescent Gardens?
I've always loved natives but it was studying Ecology and Biodiversity at Victoria Uni that really got me excited about the science behind them and specifically plant breeding systems, plants do it all ways!
My first job, post University was with the collections at Te Papa, a great way to solidify what research can teach us about plants. After that I was the Propagation Specialist at WCC and really wanted to apply what I'd learned about how useful data collection is to the propagation of plants. I was really motivated to see to what we could learn if we could gather enough data about propagation processes and outcomes.
I wanted to make a start on converting anecdotes into science. That data along with a huge demand for prop information from a growing number of dedicated community groups led to the Wild Fruits of Wellington blog site I designed and authored. Virescent Gardens is a broad Horticulture venture that is mostly me but sometimes others too.
Alongside the on-the-ground stuff I've really enjoyed the education opportunities the most, a dabble in a few Enviroschools activities, public and community group talks and workshops, that's the stuff I'm really passionate about.
I always wanted Virescent Gardens to include a nursery, it's just taken a bit of time to land at a site where that can happen. My aim is to eventually have a supply of some more obscure, hard-to-grow, uncommon species to augment the bulk plantings around the region.
Virescent Gardens in Stokes Valley
What is the philosophy behind your company, and how does it inform the way you approach your work?
I think I can grab that pretty much directly from the front page of my website. Work with nature, not against it. Creating healthy resilient gardens relies on nurturing a healthy and flourishing environment using ecological principles. Understanding the intricacies of your site and drawing on extensive plant knowledge ensures the best garden solution with the added benefit of eliminating the need for harmful toxins.
I think it makes me take particular care when recommending what to plant. There's lots of choices that might survive but really, it's best to choose the ones that will thrive. My business is 100% organic reflecting my commitment to the environment. It's been really great introducing clients to a huge suite of organic products available these days as well as encouraging a 'ground up' approach to their gardens e.g. feed the soil not the plants. Once the plants have everything they need you wont need the chemicals, everything can achieve a balance.
Can you tell us about the special native trees you supply to Manawa Karioi? What makes these trees particularly suitable for that area?
What makes these trees particularly suitable for that area? Manawa Karioi is really cool because it's got such a range of environments from deep gullies to hilltops. I've supplied some special things like the large-leaved milk tree Ewekuri to increase the population and the genetic diversity they already have.
It is also great to supply some climbing rata, those sorts of things can take a while to establish in restoration sites and it's not one that is readily available. Kohekohe is one that's really needed in large numbers so I've been supplying larger numbers than they can get from council. Kamahi also is one that is so, so common but it's uncooperative in nursery production and because my nursery is in a kamahi site I have a constant supply.

Do you supply any other restoration projects in Wellington?
Only SEA at this stage and a group in Heretaunga Friends of Māwai Hākona or Mawaihakona Stream a really cool riparian strip restoration that started 23 years ago. I work directly with one of the original founders so that's been really cool
What are some of your favourite native trees or plants, and why? Do you have any personal favourites you love to grow in your own garden?
I'm completely obsessed with the tiny and tenacious members of our native flora, the hilltops and alpine environments, just stunning plants. I'm planting lots of eco-sourced stuff to use as future seed sources in my garden but it's gotta be pretty too! I use heaps of divaricating shrubs and my objective is to collect and grow as many of the local ones as possible. I like to mix these in with grasses and other strappy structural things like flaxes and Astelias to create that contrast between forms.
Given Wellington's unique climate, what are your top tips for selecting native trees successfully in the region?
Look at what's already growing in the area naturally and peer into other people's gardens and see what is thriving. The plants will tell you. If you've never ever seen a particular plant growing in your area, there might be a reason for that. If you're adventurous, just try it but bear in mind the labels in the plant shops are not detailed enough to use as a guide, seek more detailed info. Use my handy site guide list on the Nursery page of my website as a starting point. https://www.virescentgardens.com/nursery.html

Insights from the 2025 Bush Bird Survey
We're excited to share the fascinating results of the 2025 Bush Bird Survey, conducted on June 29th and 30th, 2025, at Manawa Karioi! This year's survey provides valuable insights into the birdlife thriving within our cherished reserve.
We're excited to share the fascinating results of the 2025 Bush Bird Survey, conducted on June 29th and 30th, 2025, at Manawa Karioi! This year's survey provides valuable insights into the birdlife thriving within our local reserve.
A Comprehensive Look at Our Feathered Friends
Six dedicated groups spent an hour on the afternoon of Sunday, June 29th, meticulously counting birds at various sites both within and on the edges of Manawa Karioi. To gain an even deeper understanding, one group revisited a site the following morning, and we incorporated data from two earlier counts conducted in 2023 and 2024. These nine counts offer a comprehensive picture of the bird species present and their distribution across the reserve.
The seven survey sites, stretching from north to south, included:
Greens Lookout: Offering views over the northern part of Manawa Karioi, near the top of Te Uma i Mokotia.
The Horse Paddock: Located on Te Ahi Kaa, near the Home of Compassion boundary, with views up the large northern gully.
Nature Trail Stream Bend: Focusing on birds within the most advanced regenerating bush in Manawa Karioi.
Mokopuna Lookout: Situated near Te Ahi Kaa in the central southern part of the reserve, looking mainly north.
Subdivision Lookout: Near the Rhine St entrance, providing views over the southern part of the reserve and Island Bay.
Paekawakawa Link Track - Top: Overlooking open ground on the boundary between Manawa Karioi and the Paekawakawa Reserve and the South Coast.
Key Findings: A Diverse and Familiar Avian Community
All survey sites showcased a wonderful diversity of birds, with 5 to 9 species recorded per hour and sightings ranging from 13 to 24. The horse paddock boasted the most sightings, followed closely by the top of the Paekawakawa Link Track. These more open sites provided clear views of high-flying species like gulls.
The good news is that there were no major surprises in the results – all species recorded are familiar to those who regularly visit Manawa Karioi. However, the detailed findings offer valuable insights into the types of species thriving in the reserve.
The most abundant species observed overall were:
Gulls (black-backed and red-billed)
Tauhou (silvereye)
Piwakawaka (fantail)
Blackbird
Tui
Notably, five out of these six most abundant species are native to New Zealand. This strongly suggests that our regenerating native bush is successfully attracting more native birds compared to typical garden environments. In fact, only native birds were spotted at the Nature Trail site, a testament to the maturing native bush there, even though it's close to open ground.
Adding Context: Trends from Previous Years
Three additional one-hour Bush Bird Survey counts between 2023 and 2025 provide further context to these recent findings.
A morning re-survey of the horse paddock site on Monday, June 30th, 2025 (when bird activity is often higher), revealed a greater number of species, including five not recorded the previous afternoon: kākā, pied shag, goldfinch, quail, and songthrush. Interestingly, the total count number for this re-survey was slightly lower.
An earlier winter 2024 morning count at the horse paddock showed similar diversity and count numbers to the 2025 morning count, also including kākā and pied shag, which were not seen on June 29th.
Finally, a winter 2023 morning count at the top of Union Road (another site) displayed similar diversity but a higher count number (32 sightings) compared to 2024 and 2025. This earlier count also included two species – eastern Rosella and starling – not observed in 2024 and 2025.
Detailed Bird Counts from June 2025
For those interested in the specifics, here's a summary of the bird counts at Manawa Karioi in June 2025:
These survey results reinforce the importance of our ongoing efforts to restore and maintain Manawa Karioi's native bush, providing a thriving habitat for our precious native birdlife. We look forward to continuing these surveys and observing the positive impact of our collective work.

Sealing Up The Edges of the Forest
Planting a forest is a fairly complicated process, but once you understand the stages, it's not too daunting.
Firstly, you can't just plant everything that you want in the forest all at once. You have to start off with a small range of trees and shrubs that can handle lots of sun, dry soil in summer, and wind. Especially in windy Wellington. These "pioneer species" can range from kohuhu, tarata, ngaio and akiraho through to totara, rata and rewarewa.
Once these trees get to 2+ metres in height, you need to start planting a wider range of species - things that need a bit of shelter. But also things that will eventually fill in the spaces below the canopy and above it. If you don't do this, the forest doesn't develop and can start to decline, especially if weed species become established.
It's especially important to do this on the edges of the future forest. As the canopy gets taller, the wind can get in through the edges. During severe storms as what we had this autumn, this can cause a lot of damage - breaking branches, uprooting trees and blasting leaves off. So everywhere we have a forest edge, we plant it densely with smaller trees and shrubs to keep the wind out. Key species here include wharangi, ramarama, karamu, matipo, tauhinu and korimiko.
Our track sides are the most common forest edge at Manawa Karioi, a community-led ecological restoration project in Wellington. While the canopy will eventually close over the track, this can take about two decades. Until then it's vulnerable to storms and weed infestations.
We've almost completed this planting task along Te Ahi Kaa, the 2 kilometer loop track, and have spent the last few years focusing on Moemoea track. The plantings we did on the southern end of Moemoea about 5 years ago have now grown into a dense hedge of about 20 different species. This year we will focus on the mid section of Moemoea, around where the track intersects with Te Uma I Mokotia. There are several advantages to planting a wide range range of species on forest edges. An obvious one is that if one or more species don't handle the conditions (salt-laden wind, low soil fertility etc) then you don't get canopy collapse if too many plants die off. If there is die-off, then the more suitable species will "fill the gaps".
Another reason is plant disease and pests. Putting lots of one or two species together makes it easier for pests and diseases to become established. This does occur in nature - a disease decimated a huge amount of the wharariki (mountain flax) growing on the rocky slopes on the south coast of Pōneke in the 2010s. This left large bare patches, which can potentially fill up with weed species. But fortunately there are a lot of mingimingi and hebe species in the area which will fill the empty spaces.
We only planted small patches of wharariki, and none were affected.
Lastly, make sure you plant in the right locations. Tauhinu has proved to be a valuable species on the driest upper slopes and lookout points at Manawa Karioi, where it is hard to establish much else. It's one of the most common species that are naturally establishing on the upper slopes of former farmland along the Skyline Walkway west of the Pōneke CBD. But it needs full sun, so if planted on the south side of established trees, it will quickly die.
We will also be working along the upper half of Koiwi Tohora. Like Moemoea, it's relatively sheltered from the southerly storms, but cops the northerly winds year-round.

Another view of the same area. There are several kawakawa that were planted on the south side of existing trees. They have thrived as they are protected from direct sun and wind.
Written by Ross Gardiner.
At Manawa Karioi, our goal is to restore a thriving native forest ecosystem—one that supports biodiversity, protects against erosion, and revives the cultural and ecological heritage of this whenua. The planning and planting is carried out by committee members and a dedicated group of volunteers who work together to shape a resilient, self-sustaining forest for future generations.
If you’d like to support the restoration of native forest at Manawa Karioi, there are plenty of ways to get involved. We’re always looking for volunteers to help with planting, weeding, and track maintenance—no experience needed.
You can also support us by spreading the word or donating to our project via Givealittle: givealittle.co.nz/org/manawakarioiproject. Every bit of support helps this forest grow stronger for future generations.

A Special Working Bee – Garden Bird Survey at Manawa Karioi
Sunday 29 June, 1pm–3pm
June’s last Working Bee will be a little different – instead of our usual planting and track maintenance, we’ll be turning our eyes and ears to the sky!
Manawa Karioi is taking part in the New Zealand Garden Bird Survey, a nationwide project that helps track bird populations across Aotearoa. By using our volunteer power, we’ll be able to get a detailed snapshot of the birds living in and around Manawa Karioi.
How it works:
You’ll work in small groups of 3–5 people (great for whānau or friends).
Spend 1 hour observing and recording all birds you see or hear (native and introduced) from a fixed location.
We’ll provide tally sheets and instructions, and a Komiti member will help submit results online afterwards.
With enough volunteers, we aim to cover all of Manawa Karioi, and parts of nearby bush and open areas (Paekawakawa, Tawatawa, City to Sea Walkway).
Before the day, we’ll mark suitable counting sites and share more details. No need to register – just turn up!
Meet at the Te Ahi Kā notice board at 1pm
We'll brief you, organise groups, and send you off to your bird count spots.
Want a head start? Check out the bird ID guide on the NZ Garden Bird Survey website. Some of the birds you’re likely to spot include:
Karoro / Black-backed gull (native)
House sparrow (introduced)
Tauhou / Silvereye, Pīwakawaka / Fantail, Tūī, Kererū, Kākā (all native)
Starling, Eastern rosella (introduced)
Kāruhiruhi / Pied shag (native)
Let’s listen, watch, and help build a picture of our birdlife together.
See you on Sunday 29 June!
20 years (on and off) with Manawa Karioi
Written by Vanessa Patea
When I first moved to Wellington at the start of the millennium, I discovered nestled in the hills of Island Bay, an improbable wooden building called Tapu Te Ranga Marae. Rising up behind it was what seemed like a sprawling, and equally ambitious urban/māori restoration project that was already 10 years old - Manawa Karioi.
My earliest photo of Tapu te Ranga Marae, taken around the year 2000. See the nursery in the foreground.
I didn’t know then, but I was about to get into a long-lasting and ethically non-monogamous relationship with trees, birds and this patch of land in Island Bay hills.
We’ve been in an on-again, off-again relationship for almost a quarter of a century. It’s been full of tree hugging, spontaneous reforestation dates, and some long distance longing (when I travelled to distant shores). But somehow, I found my way back. Let me tell you the story.
Me in front of Tane Whai Ora - Bruce asked me to adorn this original whare with Māori rock art motifs in 2003/2004.
I was new to the city, hanging around the marae—doing dishes, chatting with Matua Bruce, and working on an art installation in Tāne Whai Ora.
Interior: Tane Whai Ora
I have hazy memories of the restoration project back then: a bit of tree planting, some artwork here and there. The details are fuzzy, but I like to imagine how tall those trees are now, two decades on.
Volunteering with the Southern Bays restoration groups at the Island Bay Festival in Wellington.
About nine years ago, invited by Peter Russell I joined the kōmiti. It was time to commit. I had gathered experience in media, communications, and storytelling—and I realised those skills could be of service to this project. I brought my camera, comms skills, and a desire to document the story of Manawa Karioi.
I found new ways to contribute to the project. I led the refresh of our branding and online presence—logo, website, socials, newsletter, and more recently a WhatsApp members group to keep the community connected.
The Student Volunteer Army showed up to work on the hill!
Over time, we started to notice a shift. Working bees were packed. Community, corporate and research groups were contacting us. Lockdown turned the tracks into a local pilgrimage site. People were tuning in to the Manawa Karioi story—the story of Manawa Karioi was reaching further.
Reo Rua Signage on the Nature Trail.
One of my proudest moments was wrangling the reo rua signage into existence—finally helping people find their way without getting lost in the bush! We hustled some funding, got a nature trail built, and we threw a bit of an opening event to celebrate.
‘Woody’ entertains the community at the Nature Trail Opening event.
These days, I’m still in it. I show up to working bees—sometimes with a spade, often with a camera. I believe in documenting the journey, because these moments matter. Sharing them helps others see the magic of Manawa Karioi and feel invited into the story.
My connection to Tapu Te Ranga Marae has remained strong over the years, and I’m proud to have made a documentary that features the marae with a small cameo of Manawa Karioi. You can watch it here.
Some the kōmiti after a working bee.
My journey with Manawa Karioi hasn’t followed a straight path but has led to some surprising outcomes. We’ve drifted and come back - Manawa Karioi and I? We’re in it for the long haul!

After the Storm: New Life on the Slopes of Manawa Karioi
The big storm that rolled into Wellington in early May caused minor damage at Manawa Karioi. One small ngaio was blown over and a few branches broken on other trees, and some trees have suffered from salt-burn.
Things could have been worse, but fortunately the stand of pine trees along the ridge above the marae carpark were removed a couple of months ago. The pines had been suffering storm damage for years, and were becoming hazardous.
In the process of being felled, a number of them fell onto the slope above the Nature Trail. This resulted in a number of native trees being damaged or even flattened in the process.
But every cloud has a silver lining. The felling of the pines means that the soil will no longer be acidified - you may have noticed that very little grows under pine trees. And pine trees also draw a lot of moisture from the soil, severely limiting what else can grow. With the pines gone, the 30 years of native tree seeds that have accumulated on the slope will begin to germinate, quickly filling in the gaps that have been created.
The gaps also give us the opportunity to fill the area with podocarps like kahikatea, matai and miro on the lower slope, which is shaded and holds soil moisture longer into the summer.
The upper slope will provide the opportunity to plant a large stand of titoki.
Other areas we will be focusing on this season include the mid section of Moemoea, the mid section of Te Uma i Mokotia and the upper length of Koiwi Tohora. These all will involve lots of titoki. We have about 140 titoki that were grown for us, most of which are ready to plant this year.

Titoki (Alectron excelsus)
Titoki grows to about 10m high, and is quite common throughout Te Ika A Maui. It often forms the forest canopy on north-facing slopes, growing in association with rewarewa. Not many stands of titoki/rewarewa forest remain within Poneke, but there is an impressive remnant at the canopy walkway at Otari. We have planted over 100 rewarewa at Manawa Karioi, but until now we have had trouble obtaining titoki.
Titoki has small flowers, with male and female flowers being found on separate trees. Flowering occurs from spring to early summer, with the fruit capsule taking a year to mature. It then splits open to reveal one large shiny black seed that is covered with bright red, fleshy fruit. Trees can become loaded with fruit, which is targeted by birds like tui, who swallow the seed whole, thus dispersing it when they fly away.

From Risk to Resilience: Suncorp Steps Up
In recent years a group of over 20 old pine trees at Manawa Karioi were beginning to show signs of collapse and both the Tapu-Te-Ranga Trust and the Manawa Karioi Society had become concerned about the risk that these trees posed to people visiting Manawa Karioi. It was decided that to ensure the safety of visitors and volunteer workers the old pine trees should be felled.
In March 2025, arborist Richard McIntosh, with assistants Morgan and Niki, set about the job. The first day was spent working on the trees in preparation for felling – judging how and where each tree would fall and cutting branches to ensure that when the trees fell they would not get hung up in other trees and would not end up resting on their own branches suspended above the ground and a danger to anyone working near them.
Tree Fellas', Niki, Morgan and Richard with Manawa Karioi Society Chairman Chris Livesey
One tree that had already fallen into a neighbouring tree proved quite problematic to deal with. Despite using ropes to climb up into it Richard was unable to safely make the cuts high up that would have freed it. Eventually the arborists had to resort to hiring a winch to safely dislodge the tree by moving the base of the trunk after they had cut through it.
For the second day a roster of volunteers had been organised and at the start of the day the first shift of volunteers were stationed at three appropriate points on Te Ahi Kā to stop walkers and bikers from entering the work zone. Thereafter, the day was filled with the sound of chainsaws and thunderous crashes as the trees were successively felled. Cheers were heard from some of the neighbours each time there was a loud crash.
With two exceptions the felled pine trees stayed where they fell: this is what we had hoped would happen. However, two large pine trees had a mind of their own – as they fell they bounced and shot further down the hillside onto Te Ahi Kā making a considerable mess and blocking the track. For most of the day the volunteers keeping walkers and bikers out of the work area had a pretty boring time but these two trees crashing down the hillside onto the track did provide them with some excitement. It also demonstrated the value of having the volunteers stationed on the tracks to keep people away from the work area – it would have been curtains for anyone under those trees when they came crashing down! By a stroke of very good fortune the trees that fell on Te Ahi Kā narrowly missed hitting and destroying the Nature Trail signage that was there.
Richard and Morgan spent a further two days cleaning up the mess on Te Ahi Kā and ensuring that all the felled material was stable and did not create a risk for people using the tracks. With the pine trees safely down we will be able to extend our native plantings into that area but we will also need to carefully monitor and control the inevitable weed growth that will now occur.
With the two extra days of work the whole exercise turned out to be more costly than had been anticipated but again we were very fortunate in that our application to Suncorp New Zealand’s special funding project to support charities that work with vulnerable communities as well as climate/natural hazard resilience was approved and we were able to use some of that money for this work. Suncorp New Zealand is in the insurance business and owns the brands Vero and AA Insurance.

Look out for our Lookouts!
We put effort into improving our lookout points. There are currently 4 of these with seats. Gorse was removed, and only low-growing species have been planted to avoid blocking the view. We take care to keep the plantings natural-looking, but make sure we put in a variety of food sources for the birds (and consequently bird-watchers). This includes kowhai (late winter flowers for hungry nectar-feeders like tui, korimako and kaka. Kereru also eat the flowers). Wharariki provides more nectar throughout springtime, and all the lookouts have nearby rata for summer nectar.

What Did We Plant This Year?
We started the planting season in June 2024 by planting along Moemoea, the track on the upper slopes that connects us to the Berhampore Golf Course to the north and Tawatawa Reserve to the south. It's become an increasingly popular track, so we put in some effort to improve the track surface too. As it is quite high up the slope, it gets very dry in the summertime. For this reason, most of what we plant is lower-growing species that can tolerate the dry conditions and lower soil fertility. We use this to our advantage to put in locally uncommon shrubs like mingimingi.
Where there are folds in the hillside with small gullies (with better soil that holds moisture further into summer) we can put in things like totara, rewarewa and titoki in the open spots, and under established trees we add nikau, poporokaiwhiri and kohekohe. We also added a few more rata, following from the success of last year's rata plantings. Some of those flowered last summer, despite being less than 1m high.
We also focused on Te Uma I Mokotia, a track that runs roughly east-west through Manawa Karioi, linking up to Moemoea. The track surface was widened in places, and slightly rerouted in the centre stretch to make it easier to walk up and to reduce erosion.
Our planting is focusing a lot more on expanding biodiversity, with forest giants such as kahikatea, totara, matai and miro featuring more. We put in close to 30 of these podocarps (ancient conifer trees) this year.
While much of the current forest canopy at Manawa Karioi is currently ngaio, mahoe matipo and pittosporums, these will eventually become sub-canopy as the tawa, kohekohe and titoki that we have been planting in increasing numbers take over.
New Focus for planting
Our June working bees saw a focus on planting around some of our lookout points, with an emphasis on low-growing shrubs to avoid blocking the view. Stuff like wharariki, tauhinu and mingimingi.
For August, we are taking a different approach, with an emphasis on BIG. This will include putting in some future canopy species that grow from 15-20 metres tall. In sunny, drier spots this will include titoki. In shaded spots that retain soil moisture further into the summer, this will involve kohekohe and tawa.
And of course, there will be some of the forest giants planted in various locations - totara and rewarewa in sunny locations. Kahikatea, pukatea, matai and miro in more sheltered areas.
And under all that we will be putting in about 30 nikau!
Trees, tracks and a demographic shift!
There were 5 Sundays this June, which along with some pretty good weather, allowed us to get a lot done.
Today's working bee focused on Te Uma I Mokotia, a track that runs roughly east-west through the center of Manawa Karioi.
Firstly, we realigned some track to make it easier to walk on when the ground is wet. This runs through a small grove of totara. We then planted a few understorey plants such as pate and porokaiwhiri, future canopy trees such as totara, and several each of emergent species, matai and rewarewa.
A few more low-growing shrubs were added around the seat at the north end of Moemoea, and at another viewpoint seat on Te Ahi Kaa.
3 late arrivals boosted our numbers to 12, and enabled us to get some more track improvements and planting done to the top end of Te Uma I Mokotia.
We had a complete reversal of the usual age demographic for a working bee - only 2 people over 50, with nearly everyone else being under 20!
We're looking forward to having a rest during July. See you in August for more planting!
Nature Trail Opening
Press Release - Te Ara o te Wao Nui a Tāne / The Nature Trail - Opening Event.
We are inviting the community to join the Manawa Karioi committee and Tapu te Ranga Marae trust in celebrating the opening of Te Ara o te Wao Nui a Tāne/The Nature Trail. Held on Saturday, 17th February 2024 from 1pm - 2.30pm as a part of the Island Bay Festival.
Te Ara o te Wao Nui a Tāne/ The Nature Trail
Running through the oldest area of the Manawa Karioi Ecological Restoration Project is a short loop track marked on the map as Te Ara o te Wao Nui a Tāne/ The Nature Trail.
The track has been planted over the last 35 years and the canopy is well overhead. This part of the reserve has been marked for development for seven years and thanks to a generous donation from T D Mankelow Family Charitable Fund, we are able to create a special track for children and adults alike.
The Process of Developing the Trail.
We started the project by digging out some slips that had covered the track after the heavy rainfall in 2023, then we hired track clearing work to be done to open up the tracks.
We commissioned three bug hotels to be made, which is a fun way for children and adults to engage with insects and see what lives inside.
We have created a fun game of ‘Spot the Birds’ on the nature trail - we have hidden metal birds on the trail for people to find as they walk around, which encourages people to look up and see real birds too.
We worked with Metal Image signs and accredited translator Melanie Nelson to create large bilingual botanical signs to help identify some of the special trees on the track.
We have beautified the area around the spring-field stream with rocks, planting ferns and putting in new seats. It is a great place to sit, reflect and watch the baby fantails flit around the stream and pick out bugs.

Te Ara o te Wao Nui a Tāne/The Nature Trail is a short loop that starts at the base next to the Tapu te Ranga Marae car park. The Nature Trail is marked #8 on our Trail map. It is a short easy walk taking approximately 15-mins to walk. The track is sloped but it is suitable for groups of younger children and buggies. It has fun educational features to discover along the track.

CompassionFest - Honouring Kae Millar
CompassionFest seeks to remember and celebrate local heroes, this time focusing on Kae Miller who started the movement to replant native bush along the South Coast in the 1980s, when she herself was in her mid-70's.
She was a remarkable woman, and before doing this had set up NZ's second ever recycling center at the Porirua tip. Bruce Stewart joined her there and got the inspiration to use recycled materials for the marae from her. She then come to this part of the city to be close to him, he was possibly the first helper she had planting trees above Princess Bay, and he built her a meditation lodge out of recycled car crates up there which will be a venue for the festival.
It is a fascinating story, there is more about her is on the CompassionFest website if you want to read up.
See the CompassionFest program here. They have sessions on using Seaweed, customary dyeing techniques from native plants, and Kae's grandson Max Rashbrooke is ending the festival with a Symposium on her legacy at the Home of Compassion.
Kae Miller - the person we seek to remember and celebrate in our CompassionFest 2023.
As South Wellington locals, we especially celebrate her vision to replant native bush along the coast, starting with the Te Raekaihau Point above Princess Bay. A place we can all visit and enjoy today.
Nick Logan and the Adopt-a-spot scheme
After-planting care is important for some sites, especially where our plants can be smothered by fast-growing grass and other weeds. We have several small-sized sites that we are looking for people to care for over the next year or two. This will increase plant survivability and allow them to grow faster too.
We've been fortunate to have nearby resident Nick adopt an area along Te Uma I Mokotia track.
Nick Logan who has adopted a spot at Manawa Karioi.
1) Why did you decide to Adopt a Spot?
Whilst walking one day from my home in Berhampore into nearby areas of the town belt, I was disturbed by the prolific growth of Tradescantia (wandering Willie) in a small stream bed. I thought “Why doesn’t the council control these weeds”. On reflection I realised if I wanted these or other weeds to be removed, to allow regeneration of the native plants, I should do something about it myself. My walk took me into Manawa Karioi where I observed other weeds climbing into the replanted native trees, and thought I would return with secateurs to release one tree at a time from being smothered by such weeds.
2) What does your work involve?
It’s about a 25 minute walk from my home to Manawa Karioi, then I spend about 60 - 90 minutes “rescuing” a tree or two from being overwhelmed by weeds. I remove weeds from around the trunk, and spread forest mulch in its place to suppress future weeds. I mound many of the weeds into a nearby heap which I will later use as compost beneath the juvenile trees, as the soil is quite shallow and the root run is often limited. I carry out minor pruning to allow additional light onto the replanted podocarps, which are intended to become the dominant forest.

3) Tell us a little about the area you look after.
Several decades ago about twenty totara trees were planted (by others) near the top of a gully, mainly spaced about 3 metres apart, but as much as 50 metres. I want to help these trees to become better established and attain their potential as long lived forest giant. It’s a very peaceful place to be, surrounded by nature; I feel we heal each other.
New Planting at Manawa Karioi
Planting Ferns on the Nature Trail
The spring-fed stream which attracts the pīwakawaka, and has the perfect conditions for Nikau to flourish.
One focus of the Nature Trail is ferns. They are difficult to propagate, which is why we have planted very few of them. But they will establish on their own once sufficient cover is provided as they don't like too much direct sun.
Several fern species have established in locations around Manawa Karioi, and fortunately they are easy to transplant. Which is good as a lot tend to grow right on the track, where if left they will block access.
Species we will be transplanting along the Nature Trail are:
Huruhuru Whenua.
This is the most common fern around south Pōneke as its' thick glossy leaves can cope with salt-laden winds. They also give it a tropical look. It gets quite large - growing up to 1m high and 1.5m wide.
Mamaku
The tallest tree fern, Mamaku grows 20m tall, with the fronds being 4m long. It's the most common tree fern in Poneke, and while it thrives in deep, damp gullies, it can grow in quite exposed areas too.
The unfurling frond of the Ponga.
Ponga
The second tallest tree fern, Ponga grows 10m tall. The fronds have a white underside, which have been used for hundreds of years to aid with walking at night as they reflect moonlight - kind of like a torch! Also known as "Silver Fern", the Ponga frond is a common logo, particularly on sports uniforms.
People often refer to all tree ferns as "ponga", but there are 8 species of tree fern in total.
The trunk of a tree fern is actually an extension of its root system, which is why some species will grow back from sections of cut trunk.
A welcome Surprise in our Tree Order
This year we got a surprise when Wellington City Council's Berhampore plans nursery supplied 10 large Northern Rata (Meterosideros robusta) with our usual order of 500 plants.
The 2023 plant order from the Berhampore Nursery with 500 trees to be planted this June and August.
Rata used to be fairly common around Wellington, especially on sunny slopes. It often grows as an epiphyte - that's a tree that grows on another tree! But it can start life on the ground so long as it doesn't get shaded out by other faster-growing trees. We have plenty of sunny, steep slopes where we can plant them, with our June planting sessions focusing on the downhill side of Moemoea track.
Rata produces crimson coloured flowers in summer, similar to its cousin the Pohutukawa (which is not native to Wellington). The flowers are an important food source for nectar-feeding birds such as kaka, tui and korimako, as well as for native butterflies and geckos.
Please register for the working bees on Eventfinda here.
These rata have already started producing flowers and seeds before they have even been planted!

The City Nature Challenge is a great chance to help people connect with their backyards, natural environments, parks and reserves. As part of this city-wide event we are hosting a 2-hour walk through 3 of our southern restoration reserves.
If you would like to make wildlife observations as part of the City Nature Challenge, please bring your smart phone to take photos. You can sign up on the iNaturalist website and use the iNaturalist app to record any wildlife observations, this is of course optional otherwise you can just enjoy the walk and meet some great people!
The City Nature Challenge Guided Walk
The 3 Southern Reserves - The Walk Rundown
Sunday April 30th, 10.30am
The meeting point for the walk is at 10.30am at 46a Derwent street in Island Bay at the entrance of Paekawakawa Reserve. Please be on time so we can set off as a group.
The walk will begin at the entrance of Paekawakawa reserve on Derwent Street and head up the valley passing by streams, and through restored native bush in the Paekawakawa reserve. You will be treated to unique vantages of Tapu te Ranga Island and Raukawa Moana (the Cook Strait).
We will then enter the oldest restoration project in Pōneke, Manawa Karioi on Tapu te Ranga Marae land and hike along part of the loop track called Te Ahi Kā with amazing views over Island Bay Valley and back to the city.
We will depart Manawa Karioi on the ridge line and enter into Tawatawa reserve, we will past the reservoir on the City to Sea track stopping for a break at the Lizard Garden with views over Hawkins Hill and the Dog Park.
We will then head back down the hill and there is a picnic spot at the starting point for those who would like to have a picnic lunch.
We are looking forward to meeting you all and sharing our enthusiasm for our Southern reserves. We will have a few spots where we stop to tell you about the 3 reserves. Feel free to bring your dog (and a lead) and any keen children.
Please RSVP with names and contact emails to manawakarioisociety@gmail.com so we can keep track of numbers and incase of cancellation due to weather.
2022 Planting Session - Landslips and Feeding the Birds
Another planting season has finished and what a wet one it has been! While a wet winter means lots of moisture in the soil (allowing for good plant growth during spring and summer) it can also bring some challenges. Besides some less than optimal weather for some planting sessions, the main problem has been the landslips.
This season we got 700 plants in the ground, with a couple of our planting sessions being a combined effort with Southern Environment Association on our boundary with their project in Tawatawa Reserve.
As we run out of open spaces to plant the common first-stage plants into, we have continued to increase the quantity of plants that need to be put under established patches of bush. This in turn is helping provide a year-round supply of food for insects and birds, with the latter helping spread seeds around. The amount of natural regeneration of bush at Manawa Karioi is increasing. At this stage it is mostly fast-growing understorey plants such as kawakawa and rangiora, but we are seeing a lot of porokaiwhiri (also known as Pigeonwood) as well as the locally rare Towai (Streblus banksii).
We continue to plant small quantities of forest giants such as totara, kahikatea and matai each year. They can take decades until they produce fruit, but by the time they do we will have planted hundreds of them.
As for those landslips...there have been 5 significant ones this year. Surprisingly, four of them happened right at the beginning of winter and despite there being almost twice as much rain as usual, none of them got any bigger as winter progressed. The fifth slip occurred a few weeks ago at roughly the halfway point on Te Ahi Kaa.
All of the slips have been made passable to allow access, but at present everything is just too muddy to dig out. Once the tracks have dried out a bit we will put out a call for help with clearing them. We should be able to clear the 4 smaller ones in one session but the big slip will be a work in progress.

Trapping Update - May 2022
Trapping Update from Manawa Karioi.
We had a great turnout to Predator Free Wellington training with many familiar faces from the Manawa Karioi and Tawatawa trapping teams, about 18 volunteers in total.
The volunteers were trained on installing chew cards for monitoring, bait stations, and DOC200 traps.
Dan Henry from Predator Free Miramar helped with the training and gave top tips on where to install traps.
Visitors to Manawa Karioi will soon start to see a lot of blue flagging appearing as the bait lines are installed. The bait stations are being filled with pre-feed, this is non-toxic and gives the critters a free meal whilst they get used to the new devices. In the coming months this will be changed to toxic bait. When this happens the trapping team will remove any catches from the traps and dispose of them in the garbage to minimise the chance of secondary poisoning of dogs and predatory birds.
============
If you haven’t already, sign up with Predator Free Wellington to get a trap/bait station in your backyard. PFW supply the traps/stations and do the checking!
You just need to give permission to have one on your property. For more information go to https://www.pfw.org.nz/island-bay-to-cbd/
