  • The vegetation of the Aorangi Range, Southern Wairarapa

    Wardle, J. A. (1965)

    Report
    Landcare Research

    The vegetation pattern of the Aorangi Range is extremely complex. This is partly a reflection of the wide range of natural variations in site characteristics between different altitudes, aspects and slopes, but it may also be partly attributed to the influences of a number of modifying factors which have acted upon the original vegetation in various ways to produce seral and subclimax communities. The most important of these factors are: ' geological disturbance' , 'fire' , and 'introduced herbivorous mammals'. In the first section of the following account a brief summary is given of the physical nature of the range. In the second section the structure and distribution of the main vegetation types are discussed, while in the third and final section an attempt is made to describe how modifying influences have varied the nature of those main vegetation types to produce seral and subclimax communities.

  • Preliminary study of role of alpine grasshoppers in vegetation economy of depleted alpine associations

    Batcheler, C. L. (1965)

    Report
    Landcare Research

    A mark-recapture technique was tested for use in estimating populations of Brachaspis collinus, but proved inappropriate because of high rate of emigration from sample plots. A simple direct-count technique was then devised, and estimates, which can be regarded as minimum but not true census, showed populations ranging up to 20,000 per acre, This suggests biomass up to 25.5 lb per acre, an order which on the basis of food requirements of Acriditis and productivity of vegetation on such sites, suggests Brachaspis may be utilizing a critically high proportion of the vegetable matter produced. Grasshopper numbers are thought to have been low during the 1964-65 summer, and the evidence for this is discussed.

  • Annotated bibliography of N.Z. forest ecology 1928-1968

    Orwin, Joanna (1969)

    Report
    Landcare Research

    This bibliography constitutes a brief review of the literature published on forest ecology in New Zealand since Cockayne pioneered work in this field. Complete series of all the relevant journals published in N.Z. have been consulted for the years 1928 to 1968 inclusive. References to work published overseas have been included, but it is possible that not all such material has been traced.

  • Stream discharge estimation

    Johnson, F. A. (1969)

    Report
    Landcare Research

    A dilution gauging technique to measure discharges upstream and downstream from the junction of a main stream and its tributary usually involves two discharge measurements. A method that minimizes the amount of field and laboratory work has been developed. This requires only one discharge measurement, and uses three conductivity measurements to estimate the remaining discharges. The procedure used to test the validity of this modification also enabled an investigation of the accuracy of the dilution gauging method itself.

  • Surface cover in the Tutaekuri catchment headwaters

    Cunningham, A. (1968)

    Report
    Landcare Research

    The Tutaekuri catchment headwaters lie in the southeastern portion of the Kaweka Range, Hawkes Bay. Extensive areas of accelerated erosion in the headwaters supply detritus to the Tutaekuri River. This material produces unwanted aggradation in the lower reaches of the river, particularly where the Tutaekuri flows across the Heretauriga plains. During a catchment survey of the Tutaekuri headwaters in the summer of 1959/60 it was considered that one of the first requirements for a better understanding of the area was a map to show distribution of erosion surfaces and the main vegetation types. Such a map was compiled in 1960, delineating seven different types of surface cover. The object of this report is to describe the nature of these various cover types.

  • Notes on the occurrence of concrete frost and other forms of soil-ice in Canterbury beech forests

    O'Loughlin, C. L. (1964)

    Report
    Landcare Research

    The occurrence of concrete frost in beech forests in Canterbury is recorded. Indications are that its formation may be encouraged by forest depletion and/or depletion of soil litter, and/or soil compaction, themselves consequences of the introduction of exotic mammals into the forests. The possible hydrological significance of concrete frost and its possible effects on forest regeneration are briefly discussed.

  • Uses and limitations of pellet counts in the routine management and control of deer populations

    Lambert, R. E.; Batcheler, C. L. (1969)

    Report
    Landcare Research

    Pellet counts were used to determine the effect of two control operations; one in the Ruahines and one in North Westland. From the data collected it appears that poisoning and shooting campaigns in both areas have not reduced the population significantly, if at all. The uses and limitations of pellet counting are discussed and a schedule for obtaining an estimate of pellet density within an operational control block is given.

  • Lichen succession on recently deposited rock surfaces

    Orwin, Joanna (1969)

    Report
    Landcare Research

    Lichen succession was studied on seven rock surfaces of recent origin occurring below timberline in the N. Canterbury high country, N.Z. Trends derived from data on the occurrence of species, number of species, and total lichen cover are correlated with surface age. Similarities are found between the dynamics of this succession and of higher plant succession. The growth of two species, Parmelia adpicta and Rhizocarpon tinei, is discussed. It is concluded that the results may be of some use for dating similar rock surfaces less than 50 years old.

  • Notes on protection forestry in Europe

    Cunningham, A. (1967)

    Report
    Landcare Research

    From May to October 1965 by courtesy of the New Zealand Forest Service and the Swiss authorities, the writer worked at the Swiss Federal Forest Research Institute, near Zurich. In November of that year various organisations in the surrounding European countries were visited with the object of learning something of value to New Zealand protection forestry. This report presents information and observations from Europe which may be of interest or value to those engaged on protection forestry work in New Zealand. The notes cover a wide range of subjects, all of which have some bearing on protection forestry.

  • Report on vegetation, animals, and management (recommendations) for the Taramakau catchment

    Evans, G. R.; Wardle, J. A.; Hayward, J. D.; Batcheler, C. L. (1969)

    Report
    Landcare Research

    A survey of the condition of the forests, scrublands and alpine grasslands of the upper Taramakau catchment, from the headwaters to the Kelly Range, was carried out during January and February 1969. Fifty-nine permanent plots were established in the grassland, and 243 temporary plots and 20 permanent plots in the forests and scrublands. Two major and four minor alpine grasslands associations, one sub-alpine scrub, and seven forest associations were recognised. These are defined by the physiognomic dominant species. The condition and relative susceptibility of each to ground browsing mammals is described. The animal section is based on detailed reports by L.W. Best (report on the 1969 animal distribution within the Taramakau catchment), C.N. Challies (estimation of the condition of deer in the Taramakau Valley) and I.L. James (Opossum damage in the Taramakau catchment). In it, reference is made to the browsing and grazing mammals which exert significant pressure on the quality of the vegetation: red deer, chamois, opossums and hares.

  • The usefulness of some condition indices in predicting total body fat in opossums

    Bamford, J. M.; Martin, J. T. (1968)

    Report
    Landcare Research

    Total fat reserves are probably the most suitable guide to the general plane of nutrition in mammals, but to our knowledge there has been no previous attempt to correlate any of the existing condition or fat indices with this important standard. To test the sensitivity of several fat indices which could be practically used on opossums, total body fat determinations were made on thirteen male and seventeen female opossums collected in March, 1968 from the Kelly's Creek area of the Arthur's Pass National Park.
