  • Okakari Point to Cape Rodney marine reserve: a biological survey

    Ayling, Tony, 1947- (1978)

    Report
    The University of Auckland Library

    The Marine Reserve at Leigh was gazetted in November I975 but it is worth-while to trace the course of exploitation in the reserve area both before and after its official establishment. While it is difficult to determine with any accuracy the extent of exploitation in the past, some general points can be made. Commercial and amateur fishing for snapper and crayfish have been carried out for many years in this area and the original populations of both these species have probably been considerably depleted. Experienced spearfishermen operated in the reserve area from the early 1950's until the early 1970's, with a peak in this activity in the mid 1950's. These people swam long distances and speared relatively few fish and probably affected the entire reserve to a limited extent, but had a slightly greater effect in the central third of the reserve around Goat Island. The species speared by this group were primarily snapper, Kingfish, blue moki, red moki and porae. Inexperienced spearfishermen fished only in the immediate Goat Island Bay and Channel area and had a peak effect in the late 1960's and early 1970's. This group speared most species more than 20-30 cm long, especially red moki and leatherjackets. Scuba diving for crayfish, both 'commercial' and amateur, was widespread in the reserve area during the 1960's and early 1970's, adding effect of commercial pottinq.

  • The alpine grasslands of northern Fiordland

    Evans, G. R. (1972)

    Report
    Landcare Research

    The composition and watershed condition of the alpine grasslands of Northern Fiordland were recorded at 200 sample points. The vegetation was classified into 12 associations and 16 sub-associations using a combination of Sorensen's ""k"" index of similarity and a multi-linkage cluster analysis. Chionochloa crassiuscula was the most widespread association and was dominant on 60% of the plots. C. teretifolia was found only in the Murchison Mountains and C. acicularis was restricted to the grasslands on and west of the main divide. The influence of deer and wapiti on the alpine grassland was studied. The two factors which determined utilization were the area of alpine grassland compared with the area of forest, and the presence of C. acicularis swards. The area of forest compared with the area of alpine grassland is higher west of the main divide and this has resulted in a more concentrated use of these grasslands. Deer show a low preference for C. acicularis and as this species is restricted to the western grasslands, this has also led to a more concentrated use of the remaining associations on the western side.

  • Vegetation of Kaumatua Representative Basin, Ruahine Range

    Beaumont, P. E.; Roberts, Q. W. (1971)

    Report
    Landcare Research

    The catchment comprises approximately 600 acres of steep forested mountainland. Red and mountain beech forest is the dominant vegetation but there is also an area of fire-induced manuka scrub. Over most of the catchment the vegetation cover is good, but parts of the upper mountain beech probably lack an adequate cover of woody species. Animal damage is generally slight, but deer browsing is preventing regeneration of canopy species in much of the higher altitude mountain beech. Riparian wineberry is often heavily browsed by opossums, particularly in less accessible areas.

  • The forests and scrublands of the Seaward Kaikoura Range

    Wardle, J. A. (1970)

    Report
    Landcare Research

    A reconnaissance of the forests and scrublands of the Seaward Kaikoura Range was carried out during November and December 1966 and January 1967 by the staff of the Forest and Range Experiment Station, N.Z. Forest Service. The purpose of this reconnaissance was to examine the condition of the forests and scrublands and report on the influence of introduced browsing mammals on their regeneration. This report describes the composition, structure and habitat of the main forest and scrub associations and briefly summarises the influence of browsing mammals. The area surveyed includes all the Seaward Kaikoura Range, and is bounded to the north and west by the Clarence River, to the east by the sea and to the south by the Conway River. The area enclosed is approximately 450,000 acres, much of which, however has no forest or scrub cover.

  • Distribution and density of introduced animals in the northern portion of Fiordland National Park

    Report
    Landcare Research

    Approximately 680,000 acres, comprising some of the northern section of Fiordland National Park, were surveyed during the 1969-70 summer season, to estimate the status and effect of red deer and wapiti on the forests and grassland. This report deals with the distribution and abundance of animals within the survey area.

  • Moose in Fiordland

    Tustin, K. G. (1972)

    Report
    Landcare Research

    A reconnaissance of most of the area in Fiordland suspected to support a moose population was carried out between February and April, 1972. Recent evidence of moose was identified from areas in Wet Jacket Arm, in Dusky Sound and in the Seaforth Valley and some of its tributaries. Red deer have been established throughout the area for some time, and currently are locally abundant in the heads of some tributaries in Dusky Sound, Wet Jacket Arm, and in the Upper Seaforth Valley. Evidence from past records suggests that the moose population has declined and the current survey revealed that available browse is in short supply, especially considering that red deer are in high numbers in the favoured vegetation type - the seral forest. The reduction of red deer from within these areas would favour the survival of the moose herd, if it is considered desirable to maintain a moose population in New Zealand.

  • Preliminary investigations into stand structure and growth in silver beech forest in South Westland. A. Structure

    Herbert, John (1971)

    Report
    Landcare Research

    The stand structure and height growth of silver beech and important associated sub-canopy and shrub species in South Westland, New Zealand, are described. Total basal area in moderate to fully stocked stands of silver beech was relatively constant, with a mean of about 360 square feet per acre. Basal area was apparently not influenced by species composition, age class distribution, density, altitude, or general changes in site quality. The theoretical normal size class distribution for silver beech in balanced, mixed age, forest was determined. Actual size class distributions of low altitude silver beech, fuchsia, kamahi, and broadleaf showed depressions in expected stem frequency in the smaller size classes. This is equated with utilisation of the area by cattle and particularly deer.
