Assessing drivers of plantation forest productivity on eroded versus non-eroded soils on hilly and steep land in eastern North Island, New Zealand: From catchment to regional scale
(University of Waikato, 2013)The impacts of soil erosion on forest productivity in a Pinus radiata plantation forest were assessed to determine the effects of key soil properties on tree volume. Fifteen plots on soils markedly eroded (truncated) by ... -
Carbon dynamics in restiad peatlands across different timescales
(The University of Waikato, 2020)Peatlands contain one of the largest terrestrial carbon stores on the planet, and one which is known to interact with climate and global biogeochemical cycling of nutrients. Peatlands maintain their carbon primarily through ... -
Characterisation and paleoclimatic signals within tephric loess deposits aged between c. 33 to 9.5 cal ka in the Rotorua area, northern New Zealand
(University of Waikato, 2012)I studied tephric loess deposits aged between c. 33 and 9.5 cal ka in the Rotorua region, north-east central North Island. I produced a stratigraphic framework for the loess deposits and characterised them using a range ... -
Development of national extent terrain attributes (tanz), soil water balance surfaces (swatbal), and environmental surfaces, and their application for spatial modelling of pinus radiata productivity across new zealand
(The University of Waikato, 2008)The most widely distributed and commercially important forestry crop in New Zealand is Pinus radiata D. Don. Until recently foresters have focussed on maintaining plantation management systems that are highly productive, ... -
Eruption and emplacement of the 1.3-Ma Ongatiti Ignimbrite, New Zealand: Regional pathways, particle processes, and pumice evolution associated with a large-volume pyroclastic flow deposit
(The University of Waikato, 2020)Pyroclastic flows are the most devastating phenomena of explosive volcanic eruptions. These hazardous density currents are able to travel several tens of kilometers radially away from their source as fast, hot density ... -
Evaluating soil and landscape models to predict liquefaction susceptibility in the Hinuera Formation, Hamilton Basin
(The University of Waikato, 2017)The Hinuera Formation, being an extensive alluvial deposit throughout the Hamilton Basin plains, has been identified by Kleyburg (2015) as being susceptible to liquefaction. As much of the infrastructure of the Hamilton ... -
Impacts of conversion from forestry to pasture on soil physical properties of Vitrands (Pumice Soils) in central North Island, New Zealand
(IUSS, 2010-08-01)Tens of thousands of hectares of land have been converted from plantation forest to pasture in the central North Island of New Zealand between 2000 and 2010. The land use change was driven by the perceived better long term ... -
Impacts of conversion from forestry to pasture on soil physical properties of Vitrands (Pumice Soils) in the Central North Island, New Zealand
(University of Waikato, 2011)Abstract At least 30 000 hectares of land has been converted from plantation forest to pasture in the central North Island of New Zealand between 2000 and 2010. When forests are cleared for pasture the soil may undergo ... -
Impacts of forest harvesting on the performance of soil-landscape modelling in a radiata pine forest, northern New Zealand
(The University of Waikato, 2004)New Zealand's forestry industry requires new information on the spatial distribution of certain target soil properties and locally significant soil classes in order to implement sustainable and site-specific forest management ... -
Improvement in soil water availability in pastures by excavating and mixing buried soil horizons from multilayered Pumice Soils (Vitrands) at Galatea, central North Island, New Zealand
(University of Waikato, 2014)Pumice Soils (Typic Udivitrands) in the Galatea Basin in the eastern Bay of Plenty, central North Island, New Zealand, are formed on weakly weathered, coarse textured, glassy, pumice tephra deposits and associated buried ... -
Is there a salty solution to sensitive soil sliding in the Bay of Plenty, New Zealand?
(The University of Waikato, 2017)Found globally, sensitive soils are widely regarded as a key cause of slope instability. These sensitive soils often contribute to the production of large retrogressive landslides that pose significant danger to a people ... -
Palaeolimnology of Adelaide Tarn, a ~14,000-year-old low-alpine glacial lake, northwestern South Island, New Zealand
(University of Waikato, 2013)A palaeolimnology study has been carried out on a ~14,000 calendar [cal]-year-old low-alpine glacial lake, Adelaide Tarn. The lake is located in a cirque basin at ~1260 m elevation in the Tasman Mountains, just below ... -
Paleoliquefaction in Late Pleistocene alluvial sediments in the Hauraki and Hamilton basins
(University of Waikato, 2015)Liquefaction susceptibility of the Late Pleistocene Hinuera Formation volcanogenic sediments is of interest to the engineering community as it is unclear whether materials of this age will still be prone to activation by ... -
Properties and Distribution of Soils on the Ruataniwha Plains, Hawke’s Bay: A New Approach Integrating Classical and Digital Mapping Techniques
(University of Waikato, 2011)This thesis is about soil properties and their spatial distribution on the Ruataniwha Plains in central Hawke’s Bay. The Ruataniwha Plains are situated between the Ruahine Ranges in the west, Takapau in the south and ... -
Sensitive rhyolitic pyroclastic deposits in the Tauranga region: mineralogy, geomechanics and microstructure of peak and remoulded states
(University of Waikato, 2012)Soil sensitivity has previously been recognised as a significant contributor to soil failures both internationally and within New Zealand, particularly in the Tauranga region. Sensitive soils are characterised by initial ... -
Stratigraphy, chronology, and correlation of the Plio-Pleistocene (c. 2.2-0.8 Ma) Kauroa Ash sequence, western central North Island, New Zealand
(The University of Waikato, 2000)The Kauroa Ash beds (K-beds) comprise a 12-20 m-thick sequence of extremely weathered, clay-rich (40-95% <4 μm clay) beds of tephra and loess, and associated paleosols. Found in isolated remnants throughout the western ... -
Studies on carbon and DNA preservation in allophanic soils and paleosols on Holocene tephras in New Zealand
(University of Waikato, 2016)The recovery of ancient DNA (aDNA) and palaeoenvironmental DNA (PalEnDNA) from soils and sediments has enabled detailed paleontological and ecological records to be obtained. Because of the superior ability of allophanic ... -
Using a tephrostratigraphic framework to determine the past 40,000 yrs of fault rupture and paleohydrothermal activity on the east strand of the Whirinaki Fault, Ngakuru Graben, central Taupo Volcanic Zone
(University of Waikato, 2016)The Ngakuru Graben in the central Taupo Volcanic Zone, North Island, New Zealand, is largely thermally inactive, but several fossil geothermal systems have been mapped throughout the area parallel to the Whirinaki Fault ... -
Volcanology of the basaltic lava succession within the Auckland pit of the Bombay Quarry, Bombay Volcanic Complex, South Auckland Volcanic Field
(University of Waikato, 2016)The South Auckland Volcanic Field (SAVF), which was active 1.59 – 0.51 million years ago and comprises around 82 volcanic centres, represents a complete history of a monogenetic field preserved in the geological record. ...
