Common skinks were introduced to Ulva in 2005 and 2006 for ecosystem restoration, and to investigate effects of weka (Gallirallus australis scotti) predation. Skinks were monitored over 3 non-consecutive days using artificial cover objects. Where possible skinks were caught, weighed, measured and photographed. A total of 18 sightings were made which indicates a substantial drop in both populations but especially at West End Beach. A combination of insufficient habitat and predation/competition by weka are the probable causes. However some uncertainties with monitoring are acknowledged, with regard to sub-optimal weather conditions and ‘settling’ time for new ACOS. Skinks appear not to have dispersed more than 20-30 metres from their release site. -
Divaricating Plants in New Zealand in Relation to Moa Browsing
GREENWOOD AND ATKINSON: DIYARICATING PLANTS AND MOA BROWSING 21 EVOLUTION OF DIVARICATING PLANTS IN NEW ZEALAND IN RELATION TO MOA BROWSING R. M. GREENWOOD' and I. A. E. ATKINSON' SUMMAR Y: New Zealand appears to be the only country where spineless, small-leaved divaricating plants make up nearly 10% of the woody flora. Climatic explanations have been advanced to &ccount for the origin of these divaricating plants. We suggest that the divergent and interl~ced branching, the woody exterior and the tough stems of these plants are adaptations evolved in response to browsing by moas. Together with a few species of much smaHer birds, moas were the only browsing vertebrates in New Zealand prior to the arrival of man. Thq divaricate habit is probably only one of several strategies evolved by plants in response to moa browsing. However, because fioas fed in a different way from mammals there is little to support the idea that introduced browsing mammals have merely replaced moas as aQ ecological factor in New Zealand.

Reptiles and Amphibians of Otago
Society for Research on Amphibians and Reptiles in New Zealand (SRARNZ) presents Reptiles and Amphibians of Otago Otago is a large (31,251 km2) and lightly populated region of the southern South Island of Aotearoa New Zealand, stretching from the eastern coastline west to the Southern Alps. The earliest humans, of East Polynesian origin, arrived about 700 years ago. The largest settlement today is the coastal city of Dunedin (pop. >127,000), which grew from a Scottish influx in the 1800s. The Otago Regional Council administers the region, and tribal authority (mana whenua) rests with the iwi of Ngāi Tahu. Climates in the Otago region (roughly 45°– leiopelmatid frogs survive elsewhere in 47°S) range from changeable, cool- New Zealand. Two species of introduced temperate conditions near the coast to frogs are present, but there are no the near-continental climates (baking hot crocodilians, salamanders, terrestrial summers, freezing winters) of the interior. snakes or turtles. Marine turtles (mainly The region provides varied habitats for leatherback turtles, Dermochelys coriacea) herp species, including sand-dunes, visit the coastal waters of Otago but do grasslands, shrublands, wetlands, forests, not nest here. rock structures and scree slopes, some occupied to at least 1900 m above sea level. Today’s herpetofauna is dominated by lizards (solely geckos and skinks), including about 10 described species. A further 12 or more undescribed taxa are recognised Otago by tag names for conservation purposes, and we follow that approach here. All lizards in Otago are viviparous and long- lived, and remain vulnerable to ongoing habitat loss and predation by introduced mammals. -
Ecology of Scree Skinks (Oligosoma Waimatense) in O Tu Wharekai Wetland, Mid-Canterbury High Country, New Zealand
Lettink,New Zealand Monks: Journal Scree ofskink Ecology ecology (2019) 43(1): 3354 © 2018 New Zealand Ecological Society. RESEARCH Ecology of scree skinks (Oligosoma waimatense) in O Tu Wharekai Wetland, mid-Canterbury high country, New Zealand Marieke Lettink1* and Joanne M. Monks2 1Fauna Finders, 45 Park Terrace, Corsair Bay, Christchurch 8082 2Department of Conservation, Ōtepoti/Dunedin Office, PO Box 5244, Dunedin 9058 *Author for correspondence (Email: [email protected]) Published online: 17 October 2018 Abstract: Many of New Zealand’s 104 lizard taxa are restricted to the country’s main islands where they are vulnerable to a range of threats. Information on population trends and basic ecological data are lacking for most species, hampering conservation efforts. We monitored a population of scree skinks (Oligosoma waimatense; conservation status: Nationally Vulnerable) in an alluvial stream bed in O Tu Wharekai Wetland in the mid- Canterbury high country over 10 years (2008−2018) to understand aspects of the population’s ecology, and to clarify potential threats and options for management. Although there was no linear trend in scree skink capture numbers over this time, an 84% decline was observed following severe and unseasonal flooding in May 2009. Capture numbers recovered over c. 8.5 years in the absence of any species management. Skinks ranged in size from 60−114 mm (snout-to-vent length). Home range size estimates varied from 39.5 to 950 m2 (100% Minimum Convex Polygons) and their mean size was smaller than those reported for closely-related species. Photo-identification was not sufficiently accurate for long-term individual identification. -

Kirkpatrick (with two tables, four text-figures and one appendix) KIRKPATRICK, J.B., 1999 (31:x): The characteristics and management problems of the vegetation and flora of the Huntingfield area, southern Tasmania. Pap. Proc. R. Soc. Tasm. 133(1): 103-113. ISSN 0080-4703. School of Geography and Environmental Studies, University ofTasmania, GPO Box 252-78, Hobart, Tasmania, Australia 7001. The Huntingfield area has a varied vegetation, including substantial areas ofEucalyptus amygdalina heathy woodland, heath, buttongrass moorland and E. amygdalina shrubbyforest, with smaller areas ofwetland, grassland and E. ovata shrubbyforest. Six floristic communities are described for the area. Two hundred and one native vascular plant taxa, 26 moss species and ten liverworts are known from the area, which is particularly rich in orchids, two ofwhich are rare in Tasmania. Four other plant species are known to be rare and/or unreserved inTasmania. Sixty-four exotic plantspecies have been observed in the area, most ofwhich do not threaten the native biodiversity. However, a group offire-adapted shrubs are potentially serious invaders. Management problems in the area include the maintenance ofopen areas, weed invasion, pathogen invasion, introduced animals, fire, mechanised recreation, drainage from houses and roads, rubbish dumping and the gathering offirewood, sand and plants. Key Words: flora, forest, heath, Huntingfield, management, Tasmania, vegetation, wetland, woodland. INTRODUCTION species with the most cover in the shrub stratum (dominant species) was noted.

Predation As a Primary Limiting Factor: a Comparison of the Effects of Three Predator Control Regimes on South Island Robins (Petroica Australis) in Dunedin, NZ
Predation as a primary limiting factor: A comparison of the effects of three predator control regimes on South Island robins (Petroica australis) in Dunedin, NZ. A thesis submitted for the degree of Master of Science at the University of Otago, Dunedin, New Zealand Michael Alexander Terence Jones 10/02/2016 1 ACKNOWLEDGEMENTS I would like to thank Ian Jamieson for his tireless efforts as my supervisor, mentor and friend. He provided me with an opportunity to work in some of the most remarkable places in New Zealand with some of its most treasured species. He also enabled me to contribute to the field of zoology, one I have been passionate about since as early as I can remember. Without Ian’s support and guidance none of this could have been achieved. I would also like to thank Yolanda van Heezik and Phil Seddon for their willingness to take me and the robin project on after Ian’s passing. They have worked tirelessly to help me mould my thoughts and writing into a legible thesis and I will be forever grateful for their help. This research would not have been achievable without the dedication and hard work of all the field workers and volunteers over the years. I would like to thank Leon ‘Leroy Bernard’ Berard, Jamie Cooper, Fiona Gordon, Tracy Dearlove, Rebecca McMillan and Luke Easton for all the long hours they spent watching countless robins. A special thanks to Sam Ray for organising everything and making sure all the equipment was available and booked and putting up with Leon and myself over the long summer period. -
