Being a guide on Tiritiri Matangi Island
Being a guide on Tiritiri Matangi IslandAuthor: Bob BickerDate: 17th October 2023School in Southampton included sport. I would be told tomorrow we’re going to The Common, a large, forested area with sports fields, reason? to play cricket, the very word made me yawn. They’d put me in a fielding position, the ball would whistle by, I was oblivious to it as I’d be looking the other way, watching squirrels, birds and occasionally a fox. How nature worked fascinated me then, nothing’s changed. A few years later I found myself in Alderney for ten years, the northern most of the Channel Islands. One job I had there was crew on a lobster boat pulling the pots. Just north of the island was a small islet, Burhou which in the season had Puffins. I’d say to the skipper ‘ can we land there ’, seeing these fed my passion. By default, I became the person who you took injured birds to. Locals would knock on the door to hand me a wounded Cormorant, Razorbill or Guillemot. I had scant knowledge of how to help these creatures but did have a reasonable degree of success, one I’m still proud of. Go forward a few years and I’m on a ferry approaching Tiritiri Matangi to learn how to guide and then hopefully impart knowledge to our visitors of our flora and fauna and how it works and importantly how we need it. I had scant idea of the steep learning curve I was…
People power
People powerAuthor: Stacey Balich(Information sourced from 'Long term value of engaged, skilled, citizen scientists' Mel Galbraith and Hester Cooper)Date: October 2023When I first visited Tiritiri Matangi Island, I was amazed by the place. As soon as I stepped off the boat onto the wharf, the sound of bird song was amazing and I knew I was in for a great day. My family and I spent a wonderful day exploring most of the Island, taking in all the beautiful sights and sounds of nature. I fell in love with the Island and knew that I wanted to come back again and again. After visiting a few times, I decided to become a volunteer guide and that’s when I was truly inspired because of the people I was about to meet and get to know. It’s amazing how much you can learn and appreciate when you become a part of something like this. The Tiritiri Matangi Island project has been around for decades, and it stands out from other conservation initiatives because it involves a volunteer workforce. Unlike other restoration projects where academics and government scientists hold all the power, the volunteers are given the responsibility to lead projects and are treated as true partners. Mel Galbraith and Hester Cooper discuss this approach in their article, ‘Long term value of engaged, skilled, citizen scientists’. The planting program began in 1984,…
The very first stint back on the island is a new level of busy
The very first stint back on the island is a new level of busyAuthor: Emma GrayDate: 28th September 2023Header image: John SibleyThe very first stint back on the island is a new level of busy. I always think I’m ready with my island feet until I fall over for the first time and bring myself back down to earth. The hihi team is very small at the moment as we perform our pre-breeding season tasks including the survey, sugar feeding handover from the rangers, and a lot of cleaning. The pre-breeding survey entails 40 hours spent walking all the tracks and bush patches on the island, including spending time at the sugar feeders in both the morning and afternoon to see which adults are still alive and which juveniles from the previous season have made it through their first winter. Hihi juveniles have a 40% survival rate through the first winter, which we know due to our annual mark-recapture surveys. Mark recapture in the case of the hihi means banding all individuals with a unique band combination, most likely banded as chicks in the nest, and recording the individuals, their sex (in case we got it wrong) and their location/potential territory for the upcoming season. The sugar water consumption is highest on Tiritiri Matangi Island during the winter (thank you to the island rangers who keep these hungry birds fed daily) unlike other hihi sites. This is due…
From planting some of the first trees to using them for shade from the sun
From planting some of the first trees to using them for shade from the sunAuthors: Students from St Cuthbert's Year 7Date: Thursday 21st September 2023Header image credit: Martin Sanders“Today St Cuthberts Year 7 visited Tiritiri Matangi. When we arrived, we admired the crystal clear water and the beautiful greenery that surrounded the island. As we were guided around the Island by the kind guides, we experienced all the beautiful songs of the birds. We learnt so much about all the different kinds and species of birds, trees, plants and so much about the history of the Island. It was very inspiring to know that our school was part of restoring this beautiful Island. We had so much fun learning about all the cool facts our guide taught us. Our favourite fact was that some wētās, if they land on your hand, it feels the same as when your fingernails dig into your palm. Thank you so much for having us, we loved the experience.” Chloe and Lucy “Our trip to Tiritiri Matangi was spectacular! We learnt various facts about the wildlife there, all sorts of birds and most importantly we learnt about the inspiring history of the Island. Many people used to come to Tiritiri Matangi to plant trees and help make it the beautiful Island you see today. If you do something good, people will remember you! The Island of Tiritiri Matangi is invasive…
Eight long needles of light
Eight long needles of lightSourced from Tiritiri Matangi, A Model of Conservation, Anne RimmerDate: 17 September 2023Header image: 'Eight long needles of light': the David Marine Light, 1965Credit: Peter TaylorDid you know that the Tiritiri Matangi lighthouse is a Category 1 historic place? It was actually the first lighthouse to be established on the approach to Auckland in the Waitematā Harbour. Interestingly, when it was built, there were only two other lighthouses in the entire country, Pencarrow (1859) and Boulder Bank (1862). Today it is New Zealand’s oldest working lighthouse. The lighthouse in New Zealand was a remarkable feat of engineering. It was designed by McLean and Stilman Civil Engineers in London, and constructed by Simpson and Company. The prefabricated parts were shipped all the way from London to New Zealand, where they were put together. The end result was a stunning structure that served as a beacon of light for ships navigating the nearby waters. It’s impressive to think that the original light lasted a whole 60 years before being replaced with the 11 million candlepower xenon lamp in 1965. There were murmurs among Aucklanders that the Tiritiri Matangi light was inadequate, likened to “just a glimmer, like someone standing up there with a torch.” Fortunately, Sir Ernest Davis, a former mayor of Auckland,…
Tracking tunnels on Tiritiri Matangi
Tracking tunnels on Tiritiri MatangiAuthor: Neil DaviesDate: 15th September 2023Tracking tunnels on Tiritiri Matangi are used as a biosecurity monitoring tool for detecting the presence of unwanted organisms such as rats or mice. They can also build up a picture of what animals are present in a certain area. The cards inside the tunnels are inked in the middle and have peanut butter as a lure. Animals that are attracted by the smell of peanut butter enter the tunnel and walk across the ink to reach the peanut butter. When they exit the tunnel they leave footprints (and sometimes marks from the body or tail).
In the past, the cards were left out for a month but now they are put out one weekend and taken in the following weekend. Tracking cards are also being used to monitor reptiles on the island. It was through a tracking tunnel that a Norway rat was detected on the island in January 2018 with its prints appearing on the tracking card. It is the only rat incursion that we are aware of since kiore (Polynesian rats) were eradicated in 1992-3. Fortunately, it was caught within two weeks, before it was able to cause too much damage.
More typically though, footprints of skinks, geckos, wētā, wētāpunga, tuatara and birds eg. Pūweto/ spotless
crake and, occasionally, kororā/ Little penguin, show up on the cards.
How a shortage of rakes led to the creation of an extraordinary environmental legacy
How a shortage of rakes led to the creation of an extraordinary environmental legacyAuthor: Jim Eagles, taken from the Dawn Chorus Bulletin 113Date: May 2018Jim Battersby was first and foremost a Presbyterian minister, having been ordained in 1953 and retired in 1987. In an article written for a church magazine in 2006 he recalled that, ‘Like many of my generation of students, I felt the call to ministry early after leaving secondary school, and so ministry became my whole career. I served 22 years in three parishes, and about 13 years in a hospital chaplaincy.’ Unsurprisingly, when he retired from the ministry, it left a big gap in his life. And, as it happens, about this time the island of Tiritiri Matangi had stopped being farmed and, thanks to the efforts of people like John Craig and Neil Mitchell of Auckland University, was slowly being re-afforested under the supervision of former lighthouse keepers Ray and Barbara Walter. And the Battersbys started to get involved. Asked at one of his talks how he came to get involved, Jim said he thought the fact that he and his wife Barbie had island blood, his people coming from the Chathams and hers from the Isle of Man, made them pre-disposed to like islands. But the immediate reason was that when he was chaplain at Greenlane Hospital ‘a friend who also worked there came to visit us and said she’d been…
Two men and a baby
Two men and a babyAuthor: Story shared by Vic Hunter and text taken from SoTM Dawn Chorus Bulletin No.10 May 1992Date: August 2023In January 1992, Stormy and Mr. Blue, two male takahē, successfully raised a chick. It was not unusual for male takahē to share in nest building and incubation, so it was no surprise when they showed a desire to incubate a ‘dummy egg’. Their readiness to incubate prompted DOC to find a real egg for them. A ‘spare egg’ became available when a pair on Maud Island in the Marlborough Sounds produced a clutch of two eggs. The DOC staff ferried the takahē egg by boat off Maud Island while Ray Walter was flying to Blenheim by chartered aircraft. The incubator was exchanged in a brief encounter on the tarmac at Blenheim airport, and the precious cargo was soon on its way north to another airport. Tony Monk was waiting at Ardmore with his helicopter to complete the final leg of the journey, and by mid-afternoon, the egg was safely transplanted snugly under its foster parents. It was a successful operation. It’s amazing to think that Matangi is the first takehē to hatch in this part of the country in centuries! Four days after the egg was transplanted, Matangi emerged from its shell. Ray, Barbara Walter and Vic Hunter were so diligent in caring for the chick that it even survived a potentially deadly…
Adventures in "Deep Time"
Adventures in "Deep Time"The First "Seed Plants" (Spermataphytes)Author: John SibleyImage credits: John SibleyThe ferns always had a major drawback when it came to occupying the dry land, and although their dominant sporophytes have well-developed internal tubes in their stems to carry water up to their fronds, they have a reproductive “Achilles heel” in that they possess mobile sperms with lashing tails which must swim in surface water films in order to reach female fern egg cells in order to fertilise them. The seed plants (Spermatophytes) overcame this limitation by producing male gametes (“sex cells”) in the form of dry pollen, often carried on the wind or transported stuck to insects bodies. Apart from other fundamental structural differences seeds are generally much larger than fern spores, and contain food reserves for the growth of the young embryo plant giving them a significant advantage. This subject would demand an entire episode to explore fully! These seed design breakthroughs would see the seed plants begin to replace the spore-bearing ferns as dominant players in the Gondwanan forests of the late Permian period 250 million years ago. The very first seed plants may have appeared as early as the Devonian 350 million years ago, starting with the so-called “seed ferns” but it wasn’t until the late Permian/ early Triassic periods 250 million…
Divaricating theories
Divaricating TheoriesThe puzzle of our small-leaved shrubs, moa and the ice agesAuthor: Warren BrewerVisitors sometimes comment on the marked presence of small-leaved, twiggy shrubs in our forest. Our flora contains a high proportion of these small woody shrubs which have a tight interlocking branching pattern. They are called “divaricating shrubs”. They have small leaves and tough wiry stems with a dense meshwork of branches with multiple growing points inside the shrub. They often have a brownish colour, giving an almost dead-looking appearance. Some of our trees also pass through a divaricating juvenile stage, changing to a less tangled normal growth above 3m height. These plants all lack sharp spines. Collectively they are a special New Zealand feature. Our flora contains over 50 species of these divaricates (about 10% of all our woody plants). How has this growth pattern come about? Two theories have been postulated: 1. Browsing Moa: This huge two-legged bird came to occupy the role of a four-legged grazing mammal in New Zealand. It would have spent many hours picking leaves and twigs off low trees and shrubs. Moa favoured fertile river flats, forest edges and wetlands rather than deep forests. Highly palatable and nutritious shrubs growing in this habitat would have suffered extensive damage from these birds. They, therefore, had to evolve a…
