Purpose The purpose of the five-year Key Native Ecosystem (KNE) Operational Plan for Rewanui KNE site is to: • Identify the parties involved • Summarise the ecological values and identify the threats to those values • Outline the objectives to improve ecological condition • Describe operational activities (eg, ecological weed control) that will be undertaken, who will undertake the activities and the allocated budget KNE Operational Plans are reviewed every five years to ensure the activities undertaken to protect and restore the KNE site are informed by experience and improved knowledge about the site. This KNE Operational Plan is aligned to key policy documents that are outlined below (in Section 2). 2. Policy Context Regional councils have responsibility for maintaining indigenous biodiversity, as well as protecting significant vegetation and habitats of threatened species, under the Resource Management Act 1991 (RMA)1. Plans and Strategies that guide the delivery of the KNE Programme are: Greater Wellington Long Term Plan The Long Term Plan (2018-2028)2 outlines the long term direction of the Greater Wellington Regional Council (Greater Wellington) and includes information on all our major projects, activities and programmes for the next 10 years and how they will be paid for. This document outlines that Greater Wellington will actively manage selected high value biodiversity sites. Most of this work is undertaken as part of the KNE Programme. Proposed Natural Resources Plan The Proposed Natural Resources Plan (PNRP) provides the high level strategic framework which sets out how Greater Wellington, mana whenua partners and the community work together and includes: • Guiding Principles that underpin the overall management approach of the plan (eg, Kaitiakitanga) • Sites with significant indigenous biodiversity values • Sites of significance to mana whenua (refer Schedules B, C, Schedule D) 1 Key Native Ecosystem Plan Greater Wellington Biodiversity Strategy The Greater Wellington Biodiversity Strategy3 (the Strategy) is an internal document that sets a framework that guides how Greater Wellington protects and manages biodiversity in the Wellington region to work towards the Vision. Vision Healthy ecosystems thrive in the Wellington region and provide habitat for native biodiversity The Strategy provides a common focus across Greater Wellington’s departments and guides activities relating to biodiversity. The Vision is underpinned by four operating principles and three strategic goals. Goal One drives the delivery of the KNE Programme. Goal One Areas of high biodiversity value are protected or restored 3. The Key Native Ecosystem Programme The KNE Programme is a voluntary programme of work. There is no statutory obligation for Greater Wellington to do this work. Greater Wellington invites selected landowners to discuss whether they would like to be involved in the programme. When work is done on private land, it is at the discretion of landowners, and their involvement in the programme is entirely voluntary. Involvement may just mean allowing work to be undertaken on that land. The programme seeks to protect some of the best examples of original (pre-human) ecosystem types in the Wellington region by managing, reducing, or removing threats to their ecological values. Sites with the highest biodiversity values have been identified and prioritised for management. Sites are identified as of high biodiversity value for the purposes of the KNE Programme by applying the four ecological significance criteria described below. Representativeness Rarity/ Diversity Ecological context distinctiveness The extent to which Whether ecosystems The levels of natural Whether the site ecosystems and contain ecosystem diversity provides important habitats represent Threatened/At Risk present, ie, two or core habitat, has those that were species, or species at more original high species once typical in the their geographic ecosystem types diversity, or includes region but are no limit, or whether present an ecosystem longer common rare or uncommon identified as a place ecosystems are national priority for present protection 2 Rewanui A site must be identified as ecologically significant using the above criteria and be considered “sustainable” for management in order to be considered for inclusion in the KNE Programme. “Sustainable” for the purposes of the KNE Programme is defined as: a site where the key ecological processes remain intact or continue to influence the site and resilience of the ecosystem is likely under some realistic level of management. KNE sites can be located on private or publicly owned land. However, land managed by the Department of Conservation (DOC) is generally excluded from this programme. KNE sites are managed in accordance with five-year KNE plans prepared by Greater Wellington’s Biodiversity department. Greater Wellington works with the landowners, mana whenua and other operational delivery providers to achieve mutually beneficial goals. 4. Rewanui Key Native Ecosystem site The Rewanui KNE site (188 ha) is located 21 km east of Masterton on the Masterton- Castlepoint Road in Rewanui Forest Park (formerly part of Rewanui Farm) and owned by the Montfort Trimble Foundation4. See Appendix 1, Map 1 for the KNE boundary. The KNE site contains mainly primary and regenerating native forest, though on the south-east facing hillslopes there is also retired farmland, alluvial terraces and gullies. Areas of mixed exotic forest with a secondary native forest understorey, and cut-over exotic forest with regenerating and planted secondary native forest make up the remainder. The KNE site covers some of the largest, most well-protected and intact examples of the original tōtara-tītoki forest type thought to have occurred in this area, making it one of the most valuable examples of original indigenous forest remaining in the ecological district5. It is estimated that as little as 2% (or 2,200 ha) of this forest type, most of it in a modified state, now remains in the region6. 5. Parties involved 5.1 Landowner(s)/Land Manager The whole of the Rewanui Forest Park which the Rewanui KNE site is part of is owned by the Montfort Trimble Foundation (MTF), a charitable trust. MTF was set up in 2004 under government legislation and with cooperation from Masterton District Council (MDC). Land was purchased with funds from the will of Montfort Trimble, who died in 1940 and was an advocate of public afforestation and native forest conservation. An initial purchase of 127 ha of exotic forestry north of Masterton soon led to the purchase of the 327 ha Rewanui farm property, which contained significant areas of remnant and regenerating native forest. The MTF manages this area in accordance with their overall vision of growing trees for the educational, economic and aesthetic benefit of the public. The purchase of the Rewanui farm property with its areas of native forest was based on the MTF’s desire to protect and enhance native forest, as well as public afforestation. 3 Key Native Ecosystem Plan 5.2 Operational delivery Within Greater Wellington, the Biodiversity, Biosecurity and Land Management departments are responsible for delivering the KNE operational plan. The Biodiversity department is the overarching lead department for Greater Wellington on the coordination of biodiversity management activities and advice within the KNE site. The Biosecurity department coordinates and carries out pest control activities. The Land Management department plans and advises on sustainable land use, soil conservation and water quality. Although not active within the KNE boundary, they have active Farm Environment Plans on several surrounding farms. Management partners are those that fund or have an active role in the implementation of the KNE plan or the management of the site. The MTF landowners are management partners. Their management activities, conducted across the whole Rewanui Forest Park, align well with the biodiversity management objectives in this KNE plan. These management activities include conserving and enhancing existing native forest and amenity planting and maintenance. Seasonal pest control and weed control in the amenity and plantation forestry benefits the native forest areas by reducing pests across the landscape and reducing reinvasion. The production and maintenance of exotic forest for economic purposes which both funds their activities and is part of their core business is the other major management activity in place. 5.3 Stakeholders MDC is a stakeholder as they were appointed by the MTF after its inception to initially act on their behalf and in general oversee their activities. MDC is involved with appointing some of the committee members of MTF and supporting them in their plans and aspirations. 6. Ecological values This section describes the various ecological components and attributes that make the KNE site important. These factors determine the site’s value at a

  • DISSERTATION RESTORING ISLAND BIRDS and SEED DISPERSAL in NEW ZEALAND's FENCED MAINLAND ISLAND SANCTUARIES Submitted by Sara
    DISSERTATION RESTORING ISLAND BIRDS AND SEED DISPERSAL IN NEW ZEALAND’S FENCED MAINLAND ISLAND SANCTUARIES Submitted by Sara Petrita Bombaci Graduate Degree Program in Ecology In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Summer 2018 Doctoral Committee: Advisor: Liba Pejchar Sarah Reed Julie Savidge Melinda Smith Copyright by Sara Petrita Bombaci 2018 All Rights Reserved ABSTRACT RESTORING ISLAND BIRDS AND SEED DISPERSAL IN NEW ZEALAND’S FENCED MAINLAND ISLAND SANCTUARIES Island ecosystems are global biodiversity hotspots, but many island species face population declines and extinction. These losses are mainly driven by invasive mammals that consume or compete with native animals and degrade their habitats. The decline of island animal populations may also impact ecosystem processes that depend on them, e.g. seed dispersal, pollination, and nutrient cycling. The island nation of New Zealand has pioneered a unique solution – fenced mainland island sanctuaries – which exclude invasive mammals from natural habitats and provide opportunities to restore native birds and other wildlife. Yet, critics question whether sanctuaries, which are costly and require continuous maintenance, effectively conserve birds and ecosystems, given minimal research on sanctuary project outcomes. I assessed if sanctuaries are an effective conservation tool for restoring birds and seed dispersal in New Zealand. I compared bird population densities and bird-mediated seed dispersal in three fenced sanctuary sites to three paired reference sites (with minimal mammal control). From January- April 2016 and 2017, I set seed traps to measure dispersed-seed abundance, conducted focal tree observations to determine foraging rates for six tree species, and used distance sampling-based point counts to survey birds at randomly placed sampling locations within each site.

  • The Poisonous, Suspected, and Medicinal Plants of New Zealand
    7« N.Z. JOURNAL Ol- AtiRR'.Ll.Tl'KIL feb. 20. 1923. THE POISONOUS, SUSPECTED, AND MEDICINAL PLANTS OF NEW ZEALAND. (Conlhiuett.) I). C. ASTON, IM.C., F.N.Z.Inst., Chemist to the Department. LEGUM1N0SAE. The flora of New Zealand is remarkable in containing so few genera, species, and individuals of that great family Leguininosac—the pea or pod-bearers—although it is the second largest family of flowering-plants, containing over four thousand genera and seven thousand species. Cheeseman (190b). indeed, considered (“ Manual/' p. 107) the paucity of legumes to be one of the must remarkable peculiarities of the flora. There are practically no native plants analogous to the clovers on the main islands of this Dominion, the alpine Swainsonia—the only approach to a herbaceous legume—being so rare as to be negligible. The family is represented by a comparatively small number of leafless broom-like shrubs, the well-known kowhai (Sophora tel rapt era), and the kaka-beak Cliant-hns puuiceus). Tlie kowhai is the one instance in the native flora of a suspected poisonous legume. Its affinities in other countries are certainly sus­ pected—namely, Sophora sericea and 5. secundiflora in America. The former is supposed to be one of tlie plants which cause " locoism "in horses. It may here be remarked that a number of poisonous plants in the wild pastures of America are termed " loco " weeds, the symptoms they occasion being termed " locoism." Regarding the New Zealand species of Sophora, which will probably be split up by future systematic botanists into a number of species, the only evidence tlie writer has as to the poisonous nature of the tree is that two persons were made very ill by eating food with a spoon made of kowhai wood.

  • The Vegetation of Whale Island. Part II. Species List of Vascular Plants, By
    Tane (1971) 17:39-46 39 THE VEGETATION OF WHALE ISLAND PART II. SPECIES LIST OF VASCULAR PLANTS by B.S. Parris* ABSTRACT A list of vascular plants found on Whale Island is presented together with the abundance of each species and the plant communities in which it occurs. INTRODUCTION This list was drawn up during the July visit and only a few species were added on the August visit. Further collections at more favourable seasons would probably add more species, particularly adventive annuals, to the list. The plant communities are as in Parris et al. (1971). Specimens of most species are lodged in the herbarium of the Auckland Institute and Museum. Nomenclature is as follows: indigenous dicotyledons and ferns, 'Flora of New Zealand' Vol. 1 by H.H. Allan (1961); indigenous monocotyledons, 'Flora of New Zealand' Vol. 2 by L.B. Moore and E. Edgar (1970); adventive species, 'Handbook of the Naturalised flora of New Zealand' by H.H. Allan (1941) and 'A Guide to the Identification of Weeds and Clovers' by A.J. Healy (1970).

  • 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.

  • Distribution, Ecology, Chemistry and Toxicology of Plant Stinging Hairs
    toxins Review Distribution, Ecology, Chemistry and Toxicology of Plant Stinging Hairs Hans-Jürgen Ensikat 1, Hannah Wessely 2, Marianne Engeser 2 and Maximilian Weigend 1,* 1 Nees-Institut für Biodiversität der Pflanzen, Universität Bonn, 53115 Bonn, Germany; [email protected] 2 Kekulé-Institut für Organische Chemie und Biochemie, Universität Bonn, Gerhard-Domagk-Str. 1, 53129 Bonn, Germany; [email protected] (H.W.); [email protected] (M.E.) * Correspondence: [email protected]; Tel.: +49-0228-732121 Abstract: Plant stinging hairs have fascinated humans for time immemorial. True stinging hairs are highly specialized plant structures that are able to inject a physiologically active liquid into the skin and can be differentiated from irritant hairs (causing mechanical damage only). Stinging hairs can be classified into two basic types: Urtica-type stinging hairs with the classical “hypodermic syringe” mechanism expelling only liquid, and Tragia-type stinging hairs expelling a liquid together with a sharp crystal. In total, there are some 650 plant species with stinging hairs across five remotely related plant families (i.e., belonging to different plant orders). The family Urticaceae (order Rosales) includes a total of ca. 150 stinging representatives, amongst them the well-known stinging nettles (genus Urtica). There are also some 200 stinging species in Loasaceae (order Cornales), ca. 250 stinging species in Euphorbiaceae (order Malphigiales), a handful of species in Namaceae (order Boraginales), and one in Caricaceae (order Brassicales). Stinging hairs are commonly found on most aerial parts of the plants, especially the stem and leaves, but sometimes also on flowers and fruits. The ecological role of stinging hairs in plants seems to be essentially defense against mammalian herbivores, while they appear to be essentially inefficient against invertebrate pests.

DOI: http://dx.doi.org/10.15446/abc.v22n3.61556 ABSTRACT Neotropical Piper species have bisexual flowers. Such reproductive trait is considered basal in this pantropical genus. However, neotropical species having unisexual (staminate) flowers along with bisexual ones have also been reported. Dichogamy is common in the genus, associated with either self-compatibility or -incompatibility, as well as with entomophily. We analyzed a natural population of Piper caldense in a Atlantic Forest area (Viçosa municipality, Minas Gerais state, southeastern Brazil). Preliminary observations indicated that the species produces two flower types. We analyzed flower sex in spikes of 50 plants. We obtained additional information through morphological and anatomical studies and scanning electron microscopy analyses. The longevity and exposure dynamics of stigmatic papillae and the pollen release sequence of all four stamens were investigated to verify the degree of dichogamy.
