TREATMENT BLOCK DETAILS: Treatment block Matiri Range and Valley Much of the land is covered in native forest although there is an extensive area of alpine tussocks, shrubland and riparian vegetation on the plateau and the summit of The Haystack. Forest composition reflects elevation, parent material fertility, and earthquake-induced landsliding and forest collapse. Southern rata is absent in the upper catchments but is present elsewhere at Vegetation type moderate elevation on both infertile rocks such as granite and on fertile calcareous rocks. Most areas containing rata show possum induced dieback. Seral communities are widespread on earthquake-triggered landslide deposits. However these are often dominated by herbaceous species and possum-preferred species such as fuchsia are relatively uncommon, probably reflecting a long history of browsing by ungulates and possums. The area Pestlink Ref: 0809STA03 Date Printed: 22 Dec 2008 Page 5 of 10 contains five special vulnerable and restricted plant taxa, of which Pseudopanax macintyrei and Melicytus obvatus are at highest risk from possums. Bioclimatic zone sub-montane sub-alpine montane Climate characteristics: Rainfall 1500 mm Temperature: Average Summer 18.0 Average Winter 4.0 Snow level 1000 m Altitude 340-1526 m There is no known history of usage by Maori or known Maori occupation sites within the control area. The Matiri Valley and Plateau offers remote tramping experiences. DOC has a series of Community and maintained tracks and huts in the area. This area is the southern Iwi interests entrance to the Kahurangi National Park. The area has been used extensively by hunters and Lake Matiri and other smaller lakes were visited during eeling times before the National Park status.

HORSESHOE BAY The Kingfisher by Eileen Duggan 1894-1972 The power lines of Sydney and Perth are quite a contrast to the windswept, rain lashed climate of Stewart Island for the Black- Faced Cuckoo Shrike, so spotting one on the island recently was a surprise for Brent Beaven, the Department of Conservation's CONTENTS Biodiversity Manager on Stewart Island/Rakiura. Brent spotted the rare Australian vagrant on 26th May 2011 at the Dancing President's Report 3 Star Foundation's Ecological Preserve at Horseshoe Bay.

  • Recent Studies of Historical Earthquake-Induced Landsliding, Ground Damage, and Mm Intensity
    59 RECENT STUDIES OF HISTORICAL EARTHQUAKE-INDUCED LANDSLIDING, GROUND DAMAGE, AND MM INTENSITY IN NEW ZEALAND G. T. Hancox 1, N. D. Perrin 1 and G.D. Dellow 1 ABSTRACT A study of landsliding caused by 22 historical earthquakes in New Zealand was completed at the end of 1997. The main aims of that study were to: (a) study the nature and extent of landsliding and other ground damage (sand boils, subsidence and lateral spreading due to soil liquefaction) caused by historical earthquakes; (b) determine relationships between landslide distribution and earthquake magnitude, epicentre, isoseismals, faulting, geology and topography; and (c) establish improved environmental response criteria and ground classes for assigning MM intensities and seismic hazard assessments in New Zealand. Relationships developed from the study indicate that the minimum magnitude for earthquake-induced landsliding (EIL) in N.Z. is about M 5, with significant landsliding occurring at M 6 or greater. The minimum MM intensity for landsliding is MM6, while the most common intensities for significant landsliding are MM7-8. The intensity threshold for soil liquefaction in New Zealand was found to be MM7 for sand boils, and MMS for lateral spreading, although such effects may also occur at one intensity level lower in highly susceptible materials. The minimum magnitude for liquefaction phenomena in N.Z. is about M 6, compared to M 5 overseas where highly susceptible soils are probably more widespread. Revised environmental response criteria (landsliding, subsidence, liquefaction-induced sand boils and lateral spreading) have also been established for the New Zealand MM Intensity Scale, and provisional landslide susceptibility Ground Classes developed for assigning MM intensities in areas where there are few buildings.

  • The Health of Freshwater Fish Communities in Tasman District
    State of the Environment Report The Health of Freshwater Fish Communities in Tasman District 2011 State of the Environment Report The Health of Freshwater Fish Communities in Tasman District September 2011 This report presents results of an investigation of the abundance and diversity into freshwater fish and large invertebrates in Tasman District conducted from October 2006-March 2010. Streams sampled were from Golden Bay to Tasman Bay, mostly within 20km of the coast, generally small (1st-3rd order), with varying types and degrees of habitat modification. The upper Buller catchment waterways were investigated in the summer 2010. Comparison of diversity and abundance of fish with respect to control-impact pairs of sites on some of the same water bodies is provided.

In steep mountainous terrain the abrupt increase in debris following the earthquake also leads to major sediment build up in the valley and river systems (aggradation). Where earthquakes occur in densely forested regions the trees can suffer severe damage. Some of the damage occurs simply from the earthquake shaking, in which the tree acts as a relatively top heavy inverted "pendulum", and can suffer breakage of the main trunk, side branches or root system.
