Abstract

The thesis is a review of twenty publications including refereed papers, soil survey
repurls and bulletins, soil maps and books. Also included are two major unpublished
reports.
The primary objective of the research has been the provision of information relevant
to the sustainable use of temperate forest soils. A secondary aim was to investigate
soil-forming processes. To achieve these objectives, the research has included four
main aspects:
(1) Soil surveys to determine the properties and distribution of soils.
(2) Assessment of potential soil degradation hazards resulting from forest practices.
(3) Evaluation of the productive capacity of the soils and their suitability for
plantation forestry.
( 4) Studies of some aspects of the genesis of temperate forest soils.
Research of temperate forest soils commenced with a soil survey of the CharlestonPunakaiki
region on the west coast of northern South Island, New Zealand in the
mid-l 970's. A report including ratings of soil limitations affecting the growth of
softwood plantations and a soil map at 1: 50 000 scale covering 36 500ha were
completed. Subsequent studies concentrated on the assessment of landslide hazard
and the effects of windthrow and selective logging on soil depth.
Between 1978-1982 a soil survey was carried out in the Malborough Sounds region
in northern South Island, New Zealand to assess soil limitations affecting plantation
growth and the potential impacts on site disturbance and sediment generation from
various forest practices. A soil report and map at a scale of 1: 100 OOO covering about
50 OOO ha were completed as part of the project. Transect studies ofregolith
characteristics and soil processes were also carried out. Mapping was initiated in Tasmania in 1990 to provide soil information suitable for
use by forest managers for compliance with the Forest Practices Code. Soil reports
and maps at 1 :50 OOO were completed for 154 OOOha in the north of the State together
with a handbook outlining the properties and management requirements of 3 5
important forest soils from around Tasmania. Methodologies were also developed for
assessing soil erodibility, site productivity and site suitability for plantations.
Specific research was carried out to investigate impacts on soils from cable-logging
steep slopes, and soil texture-profiles in relation to bioturbation by earthworms.
The studies in northern South Island, New Zealand and Tasmania reviewed by the
author have added substantially to information on temperate forest soils, particularly
in relation to their properties, distribution and management practices required for
sustainable use.
