Australian Wheat

Of 12 wheat samples from crops affected by head blight (caused by Fusarium graminearum) at harvest in the Northern Rivers region of New South Wales in November 1983, 11 contained up to 6.7 mg kg-1 (mean 1.8 mg kg-1) of the trichothecene mycotoxin, deoxynivalenol (DON, also known as vomitoxin). Grain feeds responsible for feed refusal and vomiting in a piggery in the region were found to contain up to 3.7 mg kg-1 of the toxin. Two triticale samples contained 9 and 11mg kg-1 of DON, but 2 barley samples were negative. A wide range of other wheat samples, principally representative of the New South Wales dryland wheat belt, were all, with 1 exception. found free of DON. Since DON can be produced in times of wet harvest, maximum limits for contamination of grains are recommended.

The effects of the different sowing rates of 20, 40, and 60 lb of seed an acre on the yield, bushel weight, composition, and response to fertilizers, of wheat grown on soils of high fertility has been studied in seven field experiments in the wheat-belt of southern New South Wales. Seasonal conditions ranged from drought to lush growing conditions and in addition one experiment was irrigated to reduce the effects of moisture stress on plant growth. Yields ranged from 10 to 70 bushels of wheat an acre and fertilizer treatments gave both positive and negative effects. For the wide range of growth conditions, variation in seeding rate had only small and non-significant effects on grain yields, with the exception of the irrigated experiment where a consistent trend indicated the need for higher seeding rates for maximum yield. Effects of the seeding rates on grain size and composition and fertilizer response, were negligible. Losses in potential grain yield, caused by the exhaustion of soil moisture reserves by excessive vegetative growth of high fertility soils before grain development has been completed, does not seem to be reduced appreciably by the use of low seeding rates.

The characteristics of the soil, vegetation and groundwater at a dryland salinity site on Miramoona, a property near Walcha on the Northern Tablelands of New South Wales, were investigated. Soil parameters measured at 23 points along a 200 m transect were highly correlated with the pattern of vegetation. Of overriding significance was soil pH, which varied from a high of over 10 on bare areas delineated by Critesion marinum and Cynodon dactylon to a low of less than 5 on grazing land supporting the growth of a wide range of pasture species. The bare areas were characterized by alkalinity. While they were sodic at all depths measured, they were only marginally saline and then only at the soil surface. The chemical composition of the groundwater collected from three piezometer tubes varied quite markedly over the site. It is hypothesized that the presence of alkaline bare areas on the Northern Tablelands is not a new problem, but rather the natural result of alternating wet and dry periods which have induced accumulation of carbonates and bicarbonates of the alkali cations, notably sodium. Drainage of the original perched swamps by the early landholders, tree clearing and the grazing of domestic livestock would have accelerated the process since European settlement. However, tree planting would appear unlikely to have any impact on the reclamation process in the short term. A more viable option would be the recreation of the original swamps in suitable situations, although this solution would create problems for grazing management.

North Eastern

A regional survey of the forests in north-eastern New South Wales recorded eight species of nocturnal forest birds and nine species of arboreal marsupials from 291 sites. Three major environmental gradients accounting for the distribution of these species in north-eastern New South Wales were identified: elevation, forest type (wet forest types having a dense mesic understorey or dry forest types having an open or sparse understorey), and logging intensity. Characteristic assemblages of species were associated with each end of these three gradients. A core group of species occurred across a wide range of environmental conditions, including logged and unlogged forest. Most species occurred with similar frequency in logged and unlogged forest. Implications for forest management are discussed.

Soil Surveys

Few soil surveys in New South Wales have utilised international soil classifications. Extensive morphological and laboratory data collected during soil surveys in the Northern Rivers region provided a strong basis for correlation with the World Reference Base for Soil Resources (WRB), Soil Taxonomy (ST), and the Australian Soil Classification (ASC). Of the 32 reference soil groups comprising the WRB, 20 were present locally; nine of the 12 ST orders were present. After re-classification of soils, correlation of the ASC with the WRB and ST was undertaken. Soils not requiring extensive laboratory analysis for classification and sharing similar central concepts were the more straightforward to correlate. Several ASC orders have unique central concepts and were therefore difficult to correlate with any one WRB reference soil group or ST order/suborder. Other soils were difficult to correlate due to differences in definitions of similar diagnostic criteria. This is most applicable to soils with strong texture-contrast and those with natric conditions. Such soils are not adequately differentiated to suit the Northern Rivers conditions. Of the two international schemes, the WRB was easier to apply locally due to the relative simplicity of the scheme. Considering certain aspects of Australian soils would improve the applicability of the WRB as a truly international framework for soil classification and correlation. Amendments to both the ASC and WRB are suggested.

This book provides readers with a unique understanding of the ways in which Aboriginal people interacted with their environment in the past at one particular location in western New South Wales. It also provides a statement showing how geoarchaeology should be conducted in a wide range of locations throughout Australia. One of the key difficulties faced by all those interested in the interaction between humans and their environment in the past is the complex array of processes acting over different spatial and temporal scales. The authors take account of this complexity by integrating three key areas of study – geomorphology, geochronology and archaeology – applied at a landscape scale, with the intention of understanding the record of how Australian Aboriginal people interacted with the environment through time and across space. This analysis is based on the results of archaeological research conducted at the University of New South Wales Fowlers Gap Arid Zone Research Station between 1999 and 2002 as part of the Western New South Wales Archaeology Program. The interdisciplinary geoarchaeological program was targeted at expanding the potential offered by archaeological deposits in western New South Wales, Australia. The book contains six chapters: the first two introduce the study area, then three data analysis chapters deal in turn with the geomorphology, geochronology and archaeology of Fowlers Gap Station. A final chapter considers the results in relation to the history of Aboriginal occupation of Fowlers Gap Station, as well as the insights they provide into Aboriginal ways of life more generally. Analyses are well illustrated through the tabulation of results and the use of figures created through Geographic Information System software.

Yield And Yield Components

Three experiments conducted in the Murrumbidgee Irrigation Area of southern New South Wales examined the influence of plant population on the yield and yield components of irrigated sunflowers. Populations ranged from 25,000 plants ha-1 to 140,000 plants ha-1. Furrow irrigation was employed with rows spaced 76 cm apart. In two of the experiments the wide range of plant populations examined had little effect on seed yield. Individual seed weight (g 1000-1) and seed number per head interacted with plant population so that seed yield was only marginally affected. In the remaining experiment, insufficient total dry matter production without improved harvest index prevented the attainment of an acceptable seed yield. There was a consistent trend for harvest index to fall with increasing plant population. Values recorded ranged from 0.36 to 0.23. Plant population had little effect on oil percentage. A plant population of 50,000 plants ha-1 is suggested as a minimum recommendation for irrigated sunflowers in southern New South Wales.

SummaryDespite a wide range in parent rock compositions, from analcime-olivine theralite to analcime-tinguaite, clinopyroxene phenocrysts in the Square Top intrusion show limited compositional variation. The crystallization trend of the pyroxenes (principally sahlites) lies approximately parallel to the diopside-hedenbergite join of the pyroxene quadrilateral, and in addition reveals slight enrichment in acmite. The limited iron enrichment in the pyroxenes (and in olivine phenocrysts in the theralites and tinguaites) stemmed from progressively more hydrous liquid fractions whose ferric/ferrous iron ratios increased during differentiation.

Consistent Approach

Although the ultimate goal of wildlife rehabilitation is to return animals to the wild, some are permanently unable to be released. Some non-releasable animals may be suitable for permanent care. The National Parks and Wildlife Service (NPWS) has the statutory role for arranging the appropriate placement of these animals in New South Wales. Under the current management framework, wildlife rehabilitators may apply for the permanent care of non-releasable animals under certain circumstances. If such an application is refused or not sought, NPWS ballots animals to suitable zoological parks and other exhibitors licensed by the Department of Primary Industries. The Frog and Tadpole Study Group rehomes non-releasable frogs with amphibian keepers licensed by NPWS. Between 2014 and 2018, 165 rehabilitation animals were placed under this framework, the majority of which were mammals (54%) and birds (41%). NPWS undertook a review of the framework in consultation with 17 stakeholder organisations. The review explored the need for a consistent approach to assessing animals as non-releasable, opposing views on when animals should be euthanased, the appropriateness of placing wild-born animals with exhibitors, and policy deficiencies resulting in placements that are not necessarily the best possible welfare outcome for the animal nor the best possible conservation outcome for the species. As non-releasable animals present themselves under a wide range of circumstances, the management framework requires a balance between consistency and pragmatism to achieve optimal animal welfare and conservation outcomes.
