The Wrybill <I>Anarhynchus Frontalis</I>: a Brief Review of Status, Threats and Work in Progress
The Wrybill Anarhynchus frontalis: a brief review of status, threats and work in progress ADRIAN C. RIEGEN '1 & JOHN E. DOWDING 2 •231 ForestHill Road, Waiatarua, Auckland 8, NewZealand, e-maih riegen @xtra.co. nz; 2p.o. BOX36-274, Merivale, Christchurch 8030, New Zealand, e-maih [email protected]. nz Riegen,A.C. & Dowding, J.E. 2003. The Wrybill Anarhynchusfrontalis:a brief review of status,threats and work in progress.Wader Study Group Bull. 100: 20-24. The Wrybill is a threatenedplover endemic to New Zealandand unique in havinga bill curvedto the right.It is specializedfor breedingon bareshingle in thebraided riverbeds of Canterburyand Otago in the SouthIsland. After breeding,almost the entirepopulation migrates north and wintersin the harboursaround Auckland. The speciesis classifiedas Vulnerable. Based on countsof winteringflocks, the population currently appears to number4,500-5,000 individuals.However, countingproblems mean that trendsare difficult to determine. The mainthreats to theWrybill arebelieved to be predationon thebreeding grounds, degradation of breeding habitat,and floodingof nests.In a recentstudy in the MackenzieBasin, predation by introducedmammals (mainly stoats,cats and possibly ferrets) had a substantialimpact on Wrybill survivaland productivity. Prey- switchingby predatorsfollowing the introductionof rabbithaemorrhagic disease in 1997 probablyincreased predationrates on breedingwaders. A recentstudy of stoatsin the TasmanRiver showedthat 11% of stoat densexamined contained Wrybill remains.Breeding habitat is beinglost in somerivers and degraded in oth- ers,mainly by waterabstraction and flow manipulation,invasion of weeds,and human recreational use. Flood- ing causessome loss of nestsbut is alsobeneficial, keeping nesting areas weed-free. The breedingrange of the speciesappears to be contractingand fragmenting, with the bulk of the popula- tion now breedingin three large catchments. -
Basemap Using the NZ Digital River Network
Building a Hydrologic Base Map Prepared by David R. Maidment Waterways Centre for Freshwater Research University of Canterbury 14 March 2018 Goals of the Exercise This exercise shows how to develop a hydrologic base map for a catchment showing the catchment boundary and the rivers and streams within it. This is done in two ways – for the Rakaia river in Canterbury using the NZ Digital River Network, and for the Puriri river catchment in Papua-New Guinea using ArcGIS Online ready to use Hydro Services. Computer and Data Requirements To carry out this exercise, you need to have a computer, which runs ArcGIS Desktop version 10.5. This exercise will also work with version 10.4.1 if you do not have access to Version 10.5. You will need a login and password for the University of Canterbury Organizational Account for ArcGIS Online. Part One: Basemap using the NZ Digital River Network Check out information about the New Zealand Digital River Network, or REC (River Environment Classification) at https://www.niwa.co.nz/freshwater-and-estuaries/management- tools/river-environment-classification-0 You can download a copy of the dataset for all of New Zealand at: https://www.niwa.co.nz/static/web/nzRec2_v4.gdb.zip This is a 487 MB file, so you need a good Wifi connection or wired internet connection to do this. When you uncompress this file, it looks like this The nzRec2_V4.gdb is a 2.2 GB geodatabase covering all of New Zealand. If you have the full REC database and you open ArcMap and look at the REC Geodatabase, below is what you see. -

Health Impact Assessment of Central Plains Water Scheme
Health Impact Assessment of Central Plains Water Scheme April 2008 Lead agency: Community and Public Health, Canterbury District Health Board HIA lead: Alistair Humphrey Report prepared by: Humphrey A, Walker M, Porteous A, Pink R, Quigley R, and Thornley L Acknowledgements This rapid health impact assessment (HIA) has benefited from the knowledge, experience and skills of many people. A steering group of Alistair Humphrey, Malcolm Walker, Ramon Pink, Andrew Porteous, Louise Thornley and Robert Quigley provided direction and insight into the process. An initial scoping meeting was held and stakeholders were invited to set the boundaries for the HIA. A list of invited members and participants is attached as Appendix 1. A number of people provided valuable advice to the steering group beyond attendance at the meetings; Martin Ward, Margaret Leonard, Carl Hansen, Richard English, Geoff Fougere, Miria Lange, Professors Tony Blakely, Valerie Brown, Peter Crampton, Paul Dalziel, and Karen Witten. Finally, Gina Erceg and others in the administration team of Community & Public Health provided valuable support in word processing and administration, often at short notice at a difficult time of year. 2 Table of contents Acknowledgements................................................................................. 2 Executive Summary ................................................................................ 4 1.

Hydrological Effects of the M W 7.1 Darfield (Canterbury) Earthquake, 4
New Zealand Journal of Geologyand Geophysics Vol. 55, No. 3, September 2012, 231Á247 1 Hydrological effects of the MW 7.1 Darfield (Canterbury) earthquake, 4 September 2010, New Zealand SC Coxa*, HK Rutterb, A Simsc, M Mangad, JJ Weirb, T Ezzye,PAWhitef, TW Hortong and D Scotte aGNS Science, Dunedin, New Zealand; bAqualinc Research Ltd, Christchurch, New Zealand; cDepartment of Geography, University of Otago, Dunedin, New Zealand; dDepartment of Earth and PlanetaryScience, Universityof California, Berkeley,California, USA; eEnvironment Canterbury, Christchurch, New Zealand; fGNS Science, Taupo, New Zealand; gGeological Sciences, Universityof Canterbury,Christchurch, New Zealand (Received 7 December 2011; final version received 14 March 2012) The MW7.1 Darfield (Canterbury) earthquake on 4 September 2010 generated widespread hydrological effects ranging from near-instantaneous coseismic liquefaction and changes of groundwater levels in boreholes, to more sustained (days to weeks) post-seismic changes in spring flow, river discharge and groundwater piezometric levels, to longer term shifts in groundwater level one year after the earthquake. Groundwater piezometric responses include local groundwater level increases of 20 m around the Greendale Fault, particularly in deep aquifers (80 m), whereas decreases occurred in coastal confined aquifers beneath Christchurch city. Increases of up to 5 m persisted within 20 km of the fault 12 h after the earthquake. Groundwater levels and springs were affected throughout New Zealand, from 350 km away in Southland to nearly 1000 km away in Northland, even where shaking intensities were less than Modified Mercalli Intensity (MM) 3Á4 (weak to largely observed) and peak ground acceleration was much B0.01 g. Release of artesian groundwater pressure and groundwater flow are postulated to have played pivotal roles in Christchurch liquefaction. -

Presentation of September 4, 2010 Canterbury Earthquake
Presentation of September 4, 2010 Canterbury Earthquake William Godwin, PG, CEG AEG Vice President, 2019-20 Webinar – May 6, 2020 Introduction ► This presentation is on the 2010 Mw 7.1 Canterbury Earthquake. The earthquake occurred as I was traveling from San Francisco to Auckland, New Zealand to attend the IAEG Congress. Upon arrival I was asked to join the Geotechnical Extreme Events Reconnaissance (GEER) team to document damage from the event in the Christchurch area of the South Island. Little did I know that another smaller (Mw 6.2), yet deadlier earthquake would strike 5 months later in close to the same area. Introduction ► The purpose of the GEER is to observe and record earthquake induced phenomena and impacts to infrastructure before evidence is removed or altered as part of cleanup efforts. ► The reconnaissance was conducted by a joint USA-NZ-Japan team with the main funding for the USA contingent coming from GEER and partial support from PEER and EERI. ► This presentation includes my photographs from Sept. 8-10 supplemented with a few photos and observations noted in the GEER report, Nov. 2010. I also describe other seismic events from 2011-16. Sept 4th Darfield Earthquake ► At 4:35 am on September 4th NZ Standard Time (16:35 Sept 3rd UTC) the rupture of a previously unrecognized strike-slip fault (Greendale Fault) beneath the Canterbury Plains of New Zealand’s South Island produced a Mw 7.1 earthquake that caused widespread damage throughout the region. Surprisingly only two people were seriously injured, with approximately 100 total injuries. This compares with 185 deaths in the 2011 event Canterbury Earthquake Sequence Greendale Fault Rupture Characteristics Epicenter (focal) depth: 10.8km Tectonic Setting Ground Motion (pga) Geographical Setting Preliminary Observations ► Rock Avalanche, Castle Rock Reserve, Littleton, Christchurch ► Fault Offset, Telegraph Rd at Grange Rd. -
