  • Risk assessment for the establishment of West Nile virus in New Zealand

    Spurr, Eric B.; Sandlant, Graham R. (2004)

    Book
    Landcare Research

    An assessment of the risk that West Nile virus (WNV) might establish in New Zealand was conducted by comparing the taxonomic relatedness of potential vectors and hosts in New Zealand to known WNV vectors and hosts overseas, and assessing whether WNV might survive and spread after arriving. We also reviewed surveillance strategies currently used in North America to detect outbreaks of WNV, and assessed whether they are relevant to New Zealand or whether other strategies should be used.

  • Land use capability classification of the Northland region : a report to accompany the second edition, New Zealand land resource inventory

    Harmsworth, G. R. (1996)

    Book
    Landcare Research

    The report describes the second-edition Land Use Capability (LUC) classification of the Northland region, an area of 1 582 698 ha (15 827 km2) in the north of the North Island, New Zealand. This region is one of 11 in the New Zealand Land Resource Inventory (NZLRI). The NZLRI provides a physical-resource inventory for land-resource and land-use planning, particularly for evaluating the potential of land for sustained production, using the Land Use Capability system of land classification. Fieldwork for the second-edition worksheets at 1:50 000 scale began in 1985 and was completed in 1990. A total of 11718 inventory map units were delineated in the Northland region. These map units were grouped into 91 LUC units on the basis of their management requirements, soil conservation needs and land-use potential. The LUC units have been arranged into eight LUC suites - groupings of LUC units which, although differing in capability, share a definitive physical characteristic that unites them in the landscape. Within LUC suites, LUC units are further grouped into LUC subsuites according to features such as micro-topography, rock-type characteristics (e.g. composition, age) soil type, erosion potential, wetness, and management. A description of Northland region's physical land resources is provided, as well as a key to the recognition of LUC units in LUC suites, and descriptions of each LUC unit.

  • Provisional targets for soil quality indicators in New Zealand

    Sparling, Graham; Lilburne, Linda; Vojvodić-Vuković, Maja (2008)

    Book
    Landcare Research

    To judge the quality of a soil for production and environmental goals, the physical, chemical and biological properties of the soil need to be compared against the desirable condition for that land use. Ideally, a response curve is needed that shows the relationship between a quantitative soil characteristic and the quality ranking. Currently, soil quality response curves are poorly defined and there are no internationally agreed standards. This report explains how response curves were obtained for a number of key soil properties used for soil quality assessment in New Zealand, and presents the curves in graphical and numeric form.

  • Review of Canada goose population trends, damage, and control in New Zealand

    Spurr, Eric B.; Coleman, Jim D. (2005)

    Book
    Landcare Research

    The history and management of the Canada goose (Branta canadensis L.) in New Zealand are briefly reviewed. Population trend counts in the South Island have been relatively stable over the last decade, after about 80 years of rapid increase. However, they are expanding their range outside trend count areas. Population trends in the North Island indicate rapidly increasing numbers. Most geese breed around inland high-country lakes and rivers and then move to coastal lakes and rivers to moult and feed for the remainder of the year. Damage by geese is multifaceted, but their economic impacts are largely unknown. Numbers are considered too high by both farming interests and urban authorities. Goose management both within New Zealand and overseas is discussed. Further research is needed to quantify the costs of goose damage, develop cost-effective methods of goose control, and improve the monitoring of goose population trends.

  • Guide to the Soils of Kaihiku-Hokonui land region

    McIntosh, Peter D. (1994)

    Book
    Landcare Research

    The Kaihiku-Hokonui land region covers about 410 000 hectares of land underlain by predominantly tuffaceous sandstone and mudstone rocks in central and eastern Southland and south Otago, New Zealand. Previous studies have established the parent material and soil variation within the region. This report collates this research, updates the soil classification, provides keys and models for the soil distribution pattern, extrapolates the information of detailed surveys to the wider area and assesses advantages and disadvantages of land for pastoral, horticultural and forestry use.

  • Criteria for defining the soil family and soil sibling : the fourth and fifth categories of the New Zealand Soil Classification

    Webb, T. H.; Lilburne, L. R. (2011)

    Book
    Landcare Research

    The New Zealand Soil Classification has defined 15 soil orders, each of which is divided successively into soil groups and subgroups (Hewitt 2010). The soil family is a fourth category, below the subgroup, that is needed to identify the physical attributes of soil profiles more precisely. Families are given a geographic name to aid in communication. The fifth category (sibling) is designated by a number and further refines the description of the physical attributes. The sibling is the primary entity depicted on soil maps. This report outlines a system for defining and naming soil families and siblings. It builds upon and replaces the 'Criteria for defining the soilform' (Clayden & Webb 1994).

  • Soils of the Conroy land system, Central Otago

    Hewitt, A. E. (1995)

    Book
    Landcare Research

    The Conroy land system includes rolling land, hill country and steeplands with a semi-arid climate around the margins of the Central Otago basins. The soils are dominantly Semiarid Soils and associated Recent Soils from schist. The land system is divided into four land components, and these in turn into land elements. The land elements form the basis of an empirical model which enables the location of soil types to be predicted. Land evaluation of soils in the Conroy land system identified the Hawksburn soils and Hawksburn bouldery soils as the most extensive versatile soils that (with irrigation) are capable of intensive use.

  • Geomorphology of the Wairau Plains : implications for floodplain management planning

    Basher, L. R.; Lynn, I. H.; Whitehouse, I. E. (1995)

    Book
    Landcare Research

    Likely future changes to the Wairau River floodplain that will be important to floodplain management (aggradation, channel avulsion, coastal progradation) are assessed from an understanding of the past and present behaviour of the river, coastal dynamics and tectonism. The major factors determining floodplain development have been changes of river gradient in response to sea level variation and tectonism, sediment source and sediment load variation, the passage of gravel waves down the Wairau, and coastal progradation. Future evolution of the Wairau Plains will be determined by the effect of climate change and sea level rise, continuing aggradation of both gravel and sand/silt, the effect of earthquakes, and the possibility of stopbank failure or overtopping.

  • New Zealand soil classification

    Hewitt, A. E. (1993)

    Book
    Landcare Research

    Version 3.0 of the Zealand Soil Classification is the culmination of a period of development from its initiation in 1983 to wide circulation of versions 1.0 and 2.0 (Hewitt 1989) for comment and testing. It represents the best attempt, given the current state of knowledge, to classify New Zealand soils. As the knowledge and understanding of New Zealand soils grows, further revisions will be necessary. Accounts of the methods used in developing the soil classification and the rationale for the classes and differentia used are in preparation. The New Zealand Soil Classification is a national soil classification intended to replace the New Zealand Genetic Soil Classification (Taylor 1948; Taylor and Cox 1956; Taylor and Pohlen 1962). The New Zealand Genetic Soil Classificaltion grew out of the need for reconnaissance mapping of the nation's soil resources. It was successful as a unifying factor in New Zealand soil science, and it played a vital role in the development of pastoral agriculture. However, modern soil surveys and land evaluations required precise definition of classes and keys for their recognition. Furthermore, a new synthesis was needed of the large body of information collected since the 1950s. The present work has grown out of the New Zealand Genetic Soil Classification and, where possible, preserves successful parts of that classification. It has also been influenced by experience in testing the US Soil Taxonomy (Leamy et al. 1983).

  • Public attitudes to rabbit calicivirus disease in New Zealand

    Wilkinson, Roger; Fitzgerald, Gerard (1998)

    Book
    Landcare Research

    Since our earlier survey of public attitudes to rabbits (Oryctolagus cuniculus) and rabbit control in 1994, Rabbit Calicivirus Disease (RCD) has been the subject of considerable media attention and public debate. This document reports on our ongoing monitoring of New Zealand public attitudes to rabbits and RCD, as the debate unfolded. This work involved seven focus groups with members of the public and selected interest groups throughout New Zealand in mid-1996, followed by a national random survey of 600 people. Half of these had been interviewed in our 1994 survey. Despite the publicity given to rabbits and RCD, people's views of rabbits and the rabbit problem changed little between our two surveys. Most people continued to hold ambivalent views of rabbits: that they were a pest and a problem, but also ""cute and furry"" and an economic resource. Public recognition of RCD was widespread, yet little was actually known about it. RCD was perceived more favourably than was poisoning rabbits, but generally less favourably than shooting. Although RCD was favoured over shooting for its effectiveness and affordability, it was less attractive than shooting on the important public criteria of safety and humaneness. The respondents were fairly evenly divided between those who gave unconditional support to the introduction of RCD to New Zealand, those who were unconditionally opposed, and those who had a conditional position. Although the attitudes of those with unconditional positions on RCD appear stable, there was still a substantial proportion of respondents with unstable, conditional positions. The unofficial release of RCD in August 1997, nearly a year after our survey, affords an opportunity to monitor public attitudes to rabbits and RCD some time after the initial wave of media coverage and public attention has passed. This would provide high quality data on the monitoring of public perceptions of a major vertebrate pest and its biological control, which could be applied to the prediction of public responses to the potential biological control of other important vertebrate pests, such as possums.
