The Responses of New Zealand's Arboreal Forest Birds to Invasive The responses of New Zealand’s arboreal forest birds to invasive mammal control Nyree Fea A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington Te Whare Wānanga o te Ūpoko o te Ika a Māui 2018 ii This thesis was conducted under the supervision of Dr. Stephen Hartley (primary supervisor) School of Biological Sciences Victoria University of Wellington Wellington, New Zealand and Associate Professor Wayne Linklater (secondary supervisor) School of Biological Sciences Victoria University of Wellington Wellington, New Zealand iii iv Abstract Introduced mammalian predators are responsible for over half of contemporary extinctions and declines of birds. Endemic bird species on islands are particularly vulnerable to invasions of mammalian predators. The native bird species that remain in New Zealand forests continue to be threatened by predation from invasive mammals, with brushtail possums (Trichosurus vulpecula) ship rats (Rattus rattus) and stoats (Mustela erminea) identified as the primary agents responsible for their ongoing decline. Extensive efforts to suppress these pests across New Zealand’s forests have created “management experiments” with potential to provide insights into the ecological forces structuring forest bird communities. To understand the effects of invasive mammals on birds, I studied responses of New Zealand bird species at different temporal and spatial scales to different intensities of control and residual densities of mammals. In my first empirical chapter (Chapter 2), I present two meta-analyses of bird responses to invasive mammal control. I collate data from biodiversity projects across New Zealand where long-term monitoring of arboreal bird species was undertaken. The projects cover a range of treatments including fenced sanctuaries, offshore islands, forests treated periodically and sites lacking significant mammal control. I found that New Zealand bird species exhibit complex responses to the varied and sustained management effort that has occurred across New Zealand’s landscape in the last fifty years. Some species show significant positive outcomes to control, notably the larger endemic species, while others, including highly endemic species, consistently decline after control. In Chapter 3, I estimate the responses of bird populations in the central New Zealand region to changes in ship rat densities. I collaborated with scientists from the Department of Conservation (DOC) and Greater Wellington Regional Council and collated biodiversity data from four restoration projects located across the central New Zealand region. I constructed multiple density impact functions (DIFs), where the effect of a change in density of a pest on a valued resource is quantified, to describe the impacts of ship rat population dynamics on native bird populations. These responses were then modelled in a meta-analysis to provide overall effects for bird populations when rat abundance increases. I identified two taxa that exhibit significant negative responses across the region: the native parakeet species (Cyanoramphus spp.) and the tomtit (Petroica macrocephala). Evidence from single projects also showed that two other species were negatively affected by increases in rats: the South v Island kaka (Nestor meridionalis) and the North Island rifleman (Acanthisitta chloris). Conversely, populations of the recently introduced silvereye (Zosterops lateralis) were resilient to rat population recovery as silvereye counts significantly increased the year after an increase in ship rat populations was observed. In Chapter 4, I monitored bird species through a 1080 mammal-control operation in the southern Wairarapa. This operation coincided with a heavy beech mast, an irruptive event that occurs every 2-6 years. Most likely because of the abundance of seed, suppression of ship rats and possums appeared to be short-lived, and detections of these two mammals returned to pre-control levels within one and two years, respectively. Short-term responses of native birds to the control operation were positive: initially, for the small-medium sized bird species (i.e. the bellbird (Anthornis melanura), rifleman, tomtit, and tui (Prosthemadera novaeseelandiae) with a delayed positive response of the largest species 2.5 years after control (the New Zealand pigeon (Hemiphaga novaeseelandiae). In my final data chapter, I focus on the nesting outcomes of a common endemic species, the North Island fantail (Rhipidura fuliginosa placabilis), to different densities of ship rats. Through intensive monitoring of over 100 fantail nests, I estimated the outcomes of nesting attempts and formulated a DIF where nesting success was modelled as a function of the abundance of ship rats at the nest micro-site. Nesting attempts suffered higher failure rates at sites with higher rat abundance however, in this study I also identified a feature of nest placement that apparently limits predation from mammals. Nests placed on thinner branches were more likely to survive rat predation, a neat trick that perhaps only the smallest of birds can manage. My thesis identifies some species as particularly vulnerable to invasive mammalian predation while others are more resilient. Understanding resilience and vulnerability in New Zealand’s bird species sheds light on historical extinctions and the processes that continue to mould New Zealand’s avifauna. I quantified responses of New Zealand forest bird species, to different levels of invasive mammal management and residual densities of mammals, with consideration of climate and forest productivity. These estimates could be applied by conservation managers to more effectively gauge future threats to native avifauna according to the attributes of bird species and present and future management scenarios. vi Acknowledgements I would like to thank my supervisor, Stephen Hartley, who has been positive and encouraging from the very first day I stepped into his office enquiring after doctoral research opportunities. I especially appreciated his open-door policy and quick responses to emails and draft manuscripts which allowed my project to stay on track. It has been a privilege working with Stephen. I would also like to thank my secondary supervisor, Associate Professor Wayne Linklater, for his guidance, and valuable feedback. I have enjoyed working with Wayne as his ideas always stimulated my entrenched and dogmatic views on conservation biology. I am indebted to the wonderful Holdsworth family who funded this doctorate. Without their generosity, my project would not have been possible. I am grateful for their financial support that allowed this research to happen but also for enabling me to further develop my abilities and my career. I was also fortunate to receive financial assistance from the team at Pukaha / Mount Bruce and from the Centre for Biodiversity and Restoration Ecology (CBRE) team at Victoria University of Wellington (VUW). I acknowledge financial support from the Aorangi Restoration Trust and TbFree New Zealand which facilitated my research on the Aorangi project. I would like to also thank James Griffiths, Nik Joice, Patrick Van Diepen, Craig Gillies, Mikey Willcox and Jerome Guillotel from the Department of Conservation (DOC), Philippa Crisp at Greater Wellington Regional Council (GW), Colin Miskelly from Te Papa, Neil Fitzgerald at Manaaki Whenua and Derek Onley for their collaborative efforts. Permitting access to their datasets, fielding my many questions and providing expert advice truly broadened the scope of my research. I am most fortunate to have also received advice at the formative stages of this degree from John Innes at Manaaki Whenua and James Griffiths and Graeme Elliott at DOC. Sharing ideas and gaining insights from this formidable team of ecologists helped me forge a clear path. And, for help in the field, I must thank Adrian Pike and Dan Crossett who were both energetic fieldworkers but also tireless coordinators of the many field trips to the mingimingi clad hills of the Aorangi and Remutaka ranges. Many thanks also to recipients of the VUW summer scholarships for assisting on these fieldtrips. I would like to also thank the farmers, land owners and councils who have allowed access to their land, especially Paul and Cherry vii Cutfield for providing accommodation when monitoring near their property. Thanks also to Raewyn Empson and Matu Booth and the team at Zealandia who were very helpful in allowing me to conduct part of my fantail research in this very special sanctuary. And thank- you to Chris Brausch for superb field assistance, thought-provoking chats and for providing illustrations for my presentations. I would also like to extend my thanks to the School of Biological Sciences administrative staff, especially the wonderful Mary Murray, for their help and assistance throughout the past three years. Plus members of my lab group (‘Bug Club’), for their comments on manuscripts and presentations, especially Charlie Clark, Olivia Vergara, Michael Jackson and Roald Bomans. I am incredibly grateful to my family for being very patient and supporting me through the tough times. I am very fortunate to have my supportive and loving siblings: Nadine, Roxanne, Kirrily, Craig and Brett. Thank-you Mum (the late Joan B. Williams), Dane (my big brother), and Dad (Kenneth H. Fea) whose pool of academic brilliance provides a lifetime of inspiration. Thank-you Dave, for being an incredibly supportive

  • New Zealand's Genetic Diversity
    1.13 NEW ZEALAND’S GENETIC DIVERSITY NEW ZEALAND’S GENETIC DIVERSITY Dennis P. Gordon National Institute of Water and Atmospheric Research, Private Bag 14901, Kilbirnie, Wellington 6022, New Zealand ABSTRACT: The known genetic diversity represented by the New Zealand biota is reviewed and summarised, largely based on a recently published New Zealand inventory of biodiversity. All kingdoms and eukaryote phyla are covered, updated to refl ect the latest phylogenetic view of Eukaryota. The total known biota comprises a nominal 57 406 species (c. 48 640 described). Subtraction of the 4889 naturalised-alien species gives a biota of 52 517 native species. A minimum (the status of a number of the unnamed species is uncertain) of 27 380 (52%) of these species are endemic (cf. 26% for Fungi, 38% for all marine species, 46% for marine Animalia, 68% for all Animalia, 78% for vascular plants and 91% for terrestrial Animalia). In passing, examples are given both of the roles of the major taxa in providing ecosystem services and of the use of genetic resources in the New Zealand economy. Key words: Animalia, Chromista, freshwater, Fungi, genetic diversity, marine, New Zealand, Prokaryota, Protozoa, terrestrial. INTRODUCTION Article 10b of the CBD calls for signatories to ‘Adopt The original brief for this chapter was to review New Zealand’s measures relating to the use of biological resources [i.e. genetic genetic resources.

    New Zealand Comprehensive II Trip Report 31st October to 16th November 2016 (17 days) The Critically Endangered South Island Takahe by Erik Forsyth Trip report compiled by Tour Leader: Erik Forsyth RBL New Zealand – Comprehensive II Trip Report 2016 2 Tour Summary New Zealand is a must for the serious seabird enthusiast. Not only will you see a variety of albatross, petrels and shearwaters, there are multiple- chances of getting out on the high seas and finding something unusual. Seabirds dominate this tour and views of most birds are alongside the boat. There are also several land birds which are unique to these islands: kiwis - terrestrial nocturnal inhabitants, the huge swamp hen-like Takahe - prehistoric in its looks and movements, and wattlebirds, the saddlebacks and Kokako - poor flyers with short wings Salvin’s Albatross by Erik Forsyth which bound along the branches and on the ground. On this tour we had so many highlights, including close encounters with North Island, South Island and Little Spotted Kiwi, Wandering, Northern and Southern Royal, Black-browed, Shy, Salvin’s and Chatham Albatrosses, Mottled and Black Petrels, Buller’s and Hutton’s Shearwater and South Island Takahe, North Island Kokako, the tiny Rifleman and the very cute New Zealand (South Island wren) Rockwren. With a few members of the group already at the hotel (the afternoon before the tour started), we jumped into our van and drove to the nearby Puketutu Island. Here we had a good introduction to New Zealand birding. Arriving at a bay, the canals were teeming with Black Swans, Australasian Shovelers, Mallard and several White-faced Herons.

THE ECOLOGICAL REQUIREMENTS OF THE NEW ZEALAND FALCON (Falco novaeseelandiae) IN PLANTATION FORESTRY A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Zoology at Massey University, Palmerston North, New Zealand Richard Seaton 2007 Adult female New Zealand falcon. D. Stewart 2003. “The hawks, eagles and falcons have been an inspiration to people of all races and creeds since the dawn of civilisation. We cannot afford to lose any species of the birds of prey without an effort commensurate with the inspiration of courage, integrity and nobility that they have given humanity…If we fail on this point, we fail in the basic philosophy of feeling a part of our universe and all that goes with it.” Morley Nelson, 2002. iii iv ABSTRACT Commercial pine plantations made up of exotic tree species are increasingly recognised as habitats that can contribute significantly to the conservation of indigenous biodiversity in New Zealand. Encouraging this biodiversity by employing sympathetic forestry management techniques not only offers benefits for indigenous flora and fauna but can also be economically advantageous for the forestry industry. The New Zealand falcon (Falco novaeseelandiae) or Karearea, is a threatened species, endemic to the islands of New Zealand, that has recently been discovered breeding in pine plantations. This research determines the ecological requirements of New Zealand falcons in this habitat, enabling recommendations for sympathetic forestry management to be made.

Amy Waldmann 2016 The Tasman parakeet (Cyanoramphus cookii) Photo: L. Ortiz-Catedral© ii ABSTRACT I studied the foraging ecology of the world’s only population of the critically endangered Tasman parakeet (Cyanoramphus cookii) on Norfolk Island, from July 2013 to March 2015. I characterised, for the first time in nearly 30 years of management, the diversity of foods consumed and seasonal trends in foraging heights and foraging group sizes. In addition to field observations, I also collated available information on the feeding biology of the genus Cyanoramphus, to understand the diversity of species and food types consumed by Tasman parakeets and their closest living relatives as a function of bill morphology. I discuss my findings in the context of the conservation of the Tasman parakeet, specifically the impending translocation of the species to Phillip Island. I demonstrate that Tasman parakeets have a broad and flexible diet that includes seeds, fruits, flowers, pollen, sori, sprout rhizomes and bark of 30 native and introduced plant species found within Norfolk Island National Park. Dry seeds (predominantly Araucaria heterophylla) are consumed most frequently during autumn (81% of diet), over a foraging area of ca.

  • SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus Carunculatus Carunculatus )
    THREATENED SPECIES RECOVERY PLAN SERIES NO.11 SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus carunculatus carunculatus ) Prepared by Andy Roberts (Southland Conservancy) for the Threatened Species Unit Threatened Species Unit Department of Conservation P.O. Box 10-420 Wellington New Zealand © 1994 ISSN 1170-3806 ISBN 0-478-01481-9 Key words: South Island saddleback, Philesturnus carunculatus carunculatus, recovery plan ABSTRACT South Island saddlebacks (tieke) were widely distributed over the South and Stewart Islands in the 19th century. Their rapid decline was documented during the latter 19th century. Following a rodent invasion on their sole remaining island habitat South Island saddlebacks were under threat of immediate extinction. This was thwarted by prompt translocations of remaining birds to nearby predator-free islands. This plan outlines conservation goals and suggests options for continuing the recovery of this subspecies. Recovery is to be achieved through a programme of island habitat restoration and saddleback translocations. Eradication of rodents and weka is promoted by this plan, in some instances this plan suggests that discussions be held with the local Iwi to determine the appropriateness of these eradications. Saddlebacks are to be introduced or re-introduced to a number of islands around the South Island coast. When recovery has been achieved South Island saddleback populations may be established on up to 26 islands with a total of about 4000 individuals. At this population level they will not be ranked as threatened, but be classified as rare and no longer requiring a programme of on-going intensive conservation management. Recovery management proposed in this plan will be undertaken jointly by Department of Conservation staff, Iwi representatives and members of the public.
