    Drone survey of Tapuwae Inc
    (Unitec Institute of Technology, 2020) Aguilar, Glenn; Unitec Institute of Technology
    The area surveyed covers the land of Tapuwae Incorporated in Te Taitokerau, Aotearoa/New Zealand. As part of a rapidly changing landscape, Hokianga’s changing natural and ecological characteristics require significant spatially relevant information to inform proper management and effective plans for the preservation and enhancement of the area’s biological, social, cultural, and economic treasures. The changes in the landscape that impact features of the area underpin the need to build a geographic information system (GIS) that provides information including highly detailed imagery of the existing land cover and geological features, landcover and vegetation characteristics. This mahi is aimed at developing detailed imagery for the description and characterisation of land cover providing relevant information and knowledge of the landscape. Flying a drone with high resolution imagery and processing in a GIS (Geographic Information System) resulted in maps of the area that allow one to closely visualize details of the ground and 3D models that allow interaction with the imagery. This report covers the results of a drone survey conducted on the 10-12th July and a follow-up flight on 21st - 23rd of September 2020. Highlights of the results refer to the maps developed and a detailed technical report at the end of the figures is included.

    Results of the drone survey for Ngaitupoto Ki Motokaraka Trust
    (Unitec Institute of Technology, 2020) Aguilar, Glenn; Unitec Institute of Technology
    The area covered in this drone survey is located in Kohukohu in Northland and contains the former Motokaraka Dairy Company. It contains a dam, pine forest that is in the process of being harvested and stands of indigenous forest. The survey was conducted to provide spatially relevant information and develop maps that will provide the knowledge required for useful planning and management. This work is carried out for the Ngaitupoto Ki Motokaraka Trust (NKMT) and the survey was conducted in October 2020.

    Drone survey of Kahakaharoa
    (Unitec Institute of Technology, 2019) Aguilar, Glenn; Unitec Institute of Technology
    The changes in the landscape that impact features of the area underpins the need to build a geographic information system (GIS) that provides information including: • Highly detailed imagery of the existing land cover and geological features. • Areas of erosion • Vegetation characteristics including areas of invasive species Through the use of a drone, collected images resulted in maps of the area that allow one to closely visualize details of the ground cover or vegetation and 3D models that allow interaction with the imagery. This report covers the results of a drone survey conducted on the 19-21st of September and a follow-up flight on 6th of November 2019 of the North head of Hokianga Harbour, with work being done to provide information for the needs of the Te Tāpairu Hirahira o Kahakaharoa and Te Puna Topu o Hokianga Trusts. The mahi is aimed at acquiring detailed imagery for the description and characterisation of land cover thereby contributing to a Geographic Information System (GIS) relevant to the needs major stakeholders. Results of the survey and highlights of the findings are included in the summary that refers to the maps developed. A detailed technical report at the end of the figures is also included.

    Waipoa Forest Trust drone survey report
    (Unitec Institute of Technology, 2018) Aguilar, Glenn; Wihongi, Hema; Gall, R.; Unitec Institute of Technology
    AIMS AND OBJECTIVES This project aims to provide relevant spatial information that will inform project planning, decision making and implementation of management measures of the Waipoua Forest Trust Area Specifically, its objectives include the determination of the characteristics of vegetation and land cover of the area, the classification of the land cover and the identification of priority areas to focus efforts on. Additionally, this project also seeks to contribute to methods for improving the usefulness and effectivity of image acquisition using a drone with sensors designed for vegetation classification.

    Conservation status of vascular plant species in Tāmaki Makaurau / Auckland
    (Auckland Council, 2022-12-19) Simpkins, E.; Woolley, J.; de Lange, Peter; Kilgour, C.; Cameron, E.K.; Melzer, S.; Unitec, Te Pūkenga; Te Pūkenga; Auckland War Memorial Museum ; Auckland Council
    The conservation status of all known indigenous vascular plant taxa in Tāmaki Makaurau / Auckland was assessed using the New Zealand Threat Classification System (NZTCS). This is the first time Auckland Council has facilitated this assessment. Department of Conservation draft regional guidelines were used and a process outlined by the Greater Wellington Regional Council followed. A total of 786 vascular plant species were identified as present in Tāmaki Makaurau / Auckland. Two hundred species were assessed as Threatened, 105 as At Risk, four as Non-resident Native (Regional Vagrant or Coloniser) and 88 as Data Deficient. Forty-five per cent of vascular plant species are Threatened or At Risk. An additional 27 species were identified that have become extinct or may have formerly occurred in the region. Auckland Council disclaims any liability whatsoever in connection with any action taken in reliance of this document for any error, deficiency, flaw or omission contained in it
