[email protected] 03 4640787 Regional Recorder: Jim Wilson PO Box 6145, Dunedin 9059 [email protected] Otago Region Newsletter 5/2016 May 2016 Lagoon bird watching in Wild Dunedin A white heron at Tomahawk Lagoon was the star attraction for twelve visitors to a Birds New Zealand event in the Wild Dunedin festival on 24 April 2016. 2 Starting early from an empty car park, four of us checked who was wading, swimming, diving, flying, eating, calling, sleeping, and standing around. Encouraged by seeing most of those behaviours entirely from birds, even after a full moon over everyone, we got busy. New birders kept us busy over two hours of watching and enquiring. Bird watchers ranged from nine years old to retired couples, and focus adjustments on our three telescopes and shared binoculars soon warmed up. The diversity of watchers caused frequent height adjustments for scope tripods and ornithologists' legs. The white heron stalked nearby shallows, with intent pauses before stabbing down at prey. Most times it got a fish, thrilling people watching through scopes, as the heron's dagger bill held the struggling fish flicking water droplets around before gulping it down. Watchers' reactions varied from wordless sudden gasps of excitement for the heron and shock at the fishes' sudden end, to exclamations of: "Oh ! it got one ! it got a fish ! Hey, see that ...!" Prey fish were native bullies, Gobiomorphus. Bullies, common in the lagoon, are also eaten by kingfishers and shags; and by trout, perch and eels.

  • Investigating Small Town Shrinkage in the Clutha District of New Zealand and the Local Response
    Investigating small town shrinkage in the Clutha District of New Zealand and the local response Mathew Husband A thesis submitted in partial fulfilment of the degree of Master of Planning at the University of Otago, Dunedin, New Zealand 1 November 2017 i Abstract Throughout history population centres, of any size, have always fluctuated in prosperity, population, and production activities. Current international trends, such as globalisation and urbanisation have created megacities with ever-expanding populations and economies. In contrast, the same trends have begun to cause shrinkage in some parts of the world. Some small towns can be particularly vulnerable to international trends which can destabilise their populations and/ or economies. Multiple examples of this are found in New Zealand such as in towns within the southern district of Clutha. Towns in the Clutha District have been impacted by the rural to urban migration trends seen across the world as well as globalisation which creates large-scale manufacturing as opposed to the relatively small manufacturing offered by small towns. Shrinkage can have negative impacts on small towns and their communities which prompts the need for a response to slow, stop or mitigate the issues related to shrinkage. This research aims to understand the impacts and responses to population loss and economic instability which has taken place in small towns within the Clutha District. The case study towns of Kaitangata and Lawrence were chosen as these towns highlight the varying geographic, social, and economic identities of the Clutha District. The aim of this thesis is to find out how councils, communities, and individuals are affected by economic and demographic change and how they are responding to the impacts of shrinkage.

  • Community Vulnerability to Elevated Sea Level and Coastal Tsunami Events in Otago
    Community vulnerability to elevated sea level and coastal tsunami events in Otago Otago Regional Council Private Bag 1954, 70 Stafford St, Dunedin 9054 Phone 03 474 0827 Fax 03 479 0015 Freephone 0800 474 082 www.orc.govt.nz © Copyright for this publication is held by the Otago Regional Council. This publication may be reproduced in whole or in part provided the source is fully and clearly acknowledged. ISBN: 978 0 478 37630 2 Published July 2012 Prepared by Michael Goldsmith, Manager Natural Hazards, Otago Regional Council Community vulnerability to elevated sea level and coastal tsunami events in Otago i Executive summary The Otago coastline extends 480km from Chaslands in the south to the mouth of the Waitaki River in the north. Approximately 124,000 people (64% of Otago’s population) live within five kilometres of this coastline. A number of the communities situated along the coast have a level of hazard exposure to elevated sea level (or storm surge) and tsunami events. This report assesses the vulnerability (rather than the risk) 1 of these coastal communities to these hazards. The report draws on tsunami and storm surge modelling undertaken by National Institute of Water and Atmosphere (NIWA) for the Otago Regional Council (ORC) in 2007/08, coastal topography data and local knowledge of each community. This information has been used to assess how people and the communities in which they live would be affected during credible, high magnitude tsunami and elevated sea level events. It is intended that this information will: • increase community awareness of elevated sea level and tsunami hazard • inform decision making on the development of warning systems and evacuation plans • assist with the selection of land-use planning and development controls • increase the resilience of infrastructure and utilities (‘lifelines’).
