Breeding Phalaris For Tolerance To A Range Of Acid Soils, R N. Oram, A M. Ridley, J Hunter, H E. Schroeder, J Taylor
Breeding Phalaris For Tolerance To A Range Of Acid Soils, R N. Oram, A M. Ridley, J Hunter, H E. Schroeder, J Taylor
IGC Proceedings (1993-2023)
Phalaris (Phalaris aquatica L.) is a persistent, drought-hardy grass adapted lo mediterranean climates, but it is sensitive to free aluminum in acid soils. P. arundinacea L is more tolerant of soil acidity, and therefore it has been crossed to P. aquatica, followed by 1 or 2 backcrosses to P. aquatica. Open-pollinated progenies generated by I or 2 generations of random mating without selection were tested at 3 acid soil sites in Victoria and ACT. The mean herbage yields in winter were lower than the phalaris controls, but heritability and expected selection responses were high. There are good prospects …
Changing Stocking Rates And Burning Management To Reduce Greenhouse Gas Emissions From Southern Queensland Grasslands, S M. Howden, G M. Mckeon, J C. Scanlan, J O. Carter, D H. White
Changing Stocking Rates And Burning Management To Reduce Greenhouse Gas Emissions From Southern Queensland Grasslands, S M. Howden, G M. Mckeon, J C. Scanlan, J O. Carter, D H. White
IGC Proceedings (1993-2023)
GRASSMAN, an agricultural decision-support model, has been modified to include sources, sinks and storages of greenhouse gases. The modified model was used to investigate the effects of changes in stocking rate and burning management on greenhouse gas emissions of southern Queensland grasslands. These grasslands are significant net emitters of greenhouse gases in their natural state, resulting in large differences between net and anthropogenic (man-made) emissions and hence, to different conclusions regarding emission reduction strategies. At moderate stocking rates, anthropogenic emissions could be reduced by about 20% with little loss of productivity. However, similar reductions in net emissions require larger management …
Ponded Pasture Systems For Beef Production In Seasonally Dry Zones Of Northern Australia, J H. Wildin
Ponded Pasture Systems For Beef Production In Seasonally Dry Zones Of Northern Australia, J H. Wildin
IGC Proceedings (1993-2023)
In northern Australia's monsoonal zone the dry season nutritional stress is a major constraint to beef production. Between May and November the quality of dry native pastures is extremely low, particularly in digestibility, nitrogen and mineral content, and cattle lose weight. To overcome this serious constraint many innovative technologies in cattle husbandry, supplementary feeding and improved pastures have been developed, Growing water-loving grasses for green forage in the dry season using wet season water in artificial ponds is a permanent forage system being adopted commercially in central Queensland and other regions of northern Australia. Para grass (Bracltiaria mutica) …

Assessing The Productivity Of Pastures In The Central Highlands Region Of Queensland, Australia, J Willcocks, P Filet
IGC Proceedings (1993-2023)
A sustainable grazing industry requires careful management of pastures. This study measured the growth potential and productivity of different pasture types in the Central Highlands region of Queensland to develop recommendations on stocking rates which are sustainable in the long term. The most productive pasture measured, buffet grass (Cenchrus clliaris) is generally used for fattening prior to sale to the meatworks. The least productive, a mixed native pasture under a eucalypt forest, is generally used for maintaining breeding stock. Forest Mitchell grass (Bothrioclrloa ewartiana) has intermediate levels of productivity and is used for both breeding and …
Extension Through The Landcare Movement In Australia's Pastoral Zone, B R. Roberts
Extension Through The Landcare Movement In Australia's Pastoral Zone, B R. Roberts
IGC Proceedings (1993-2023)
The Landcare movement, presently based on over 1300 landholder committees nationwide, is potentially Australia's most significant popular movement ever. Its success largely depends on producers identifying with the movement and "owning" its objectives and programmes, Central to attainment of Landcare's goals is the support given by technical advisors, These advisors require a special understanding of group extension techniques, group dynamics and the subtleties of invisible leadership when appropriate. In the vast pastoral zone of Australia, where highly independent graziers operate very individualistically, the required group extension is a special challenge to committed advisory officers.
Adopting New Technologies For Grazing Lands: The Role Of Decision Systems, John A. Ludwig, Steve Marsden
Adopting New Technologies For Grazing Lands: The Role Of Decision Systems, John A. Ludwig, Steve Marsden
IGC Proceedings (1993-2023)
The management of Australia's arid and semi-arid grazing lands involves the consideration of many complex and interconnected issues related to both ecological and economic factors. Climates are highly variable across these lands and markets fluctuate widely; decision making is . difficult at the best of times, As new grazing and land management technologies become available through research organisations, such as CSIRO, the adoption of these technologies is a prime concern, Traditionally, State extension services provide this information to grazing land managers, which has proven effeclive for transferring information about current short-term problems (e,g,, locust plagues) and easy to apply products …

Research outputs 2022 to 2026
Non-perennial rivers are valuable water resources that support millions of humans globally, as well as unique riparian ecosystems. In Australia, the Earth's driest inhabited continent, over 70% of rivers are non-perennial due to a combination of ancient landscape, dry climates, highly variable rainfall regimes, and human interventions that have altered riverine environments. Here, we review Australian non-perennial river research incorporating geomorphology, hydrology, biogeochemistry, ecology, and Indigenous knowledges. The dominant research themes in Australia were drought, floods, salinity, dryland ecology, and water management. Future research will likely follow these themes but must address emerging threats to river systems due to climate …

Nonstationary Recharge Responses To A Drying Climate In The Gnangara Groundwater System, Western Australia, Simone Gelsinari, Sarah Bourke, James Mccallum, Don Mcfarlane, Joel Hall, Richard Silberstein, Sally Thompson
Research outputs 2022 to 2026
The response of groundwater recharge to climate change needs to be understood to enable sustainable management of groundwater systems today and in the future, yet observations of recharge over long-enough time periods to reveal responses to climate trends are scarce. Here we present a meta-analysis of 60 years of recharge studies over the Gnangara Groundwater System of South-West Western Australia, covering a period of sustained drying consistent with climate change projections. The recharge process in the area is defined by a wet winter during which rain saturates a deep, highly permeable soil profile with very low water storage capacity. Measurements …
Attitudes And Perceptions Towards Privacy And Surveillance In Australia, Aleatha J. Shanley
Attitudes And Perceptions Towards Privacy And Surveillance In Australia, Aleatha J. Shanley
Theses: Doctorates and Masters
Understanding attitudes towards privacy and surveillance technologies used to enhance security objectives is a complex, but crucial aspect for policy makers to consider. Historically, terrorism-related incidents justified the uptake of surveillance practices. More recently however, biosecurity concerns have motivated nation-states to adopt more intrusive surveillance measures. There is a growing body of literature that supports the public’s desire to maintain privacy despite fears of biological or physical threats.
This research set out to explore attitudes towards privacy and surveillance in an Australian context. Throughout the course of this endeavour, the COVID-19 pandemic emerged bringing with it a variety of track …

Research outputs 2022 to 2026
The soil in terrestrial and coastal blue carbon ecosystems is an important carbon sink. National carbon inventories require accurate assessments of soil carbon in these ecosystems to aid conservation, preservation, and nature-based climate change mitigation strategies. Here we harmonise measurements from Australia’s terrestrial and blue carbon ecosystems and apply multi-scale machine learning to derive spatially explicit estimates of soil carbon stocks and the environmental drivers of variation. We find that climate and vegetation are the primary drivers of variation at the continental scale, while ecosystem type, terrain, clay content, mineralogy and nutrients drive subregional variations. We estimate that in the …

Lead (Pb) toxicity, through ingestion of lead ammunition in carcasses, is a threat to scavenging birds worldwide, but has received little attention in Australia. We analyzed lead exposure in the wedge-tailed eagle (Aquila audax), the largest raptor species found in mainland Australia and a facultative scavenger. Eagle carcasses were collected opportunistically throughout south-eastern mainland Australia between 1996 and 2022. Lead concentrations were measured in bone samples from 62 animals via portable X-ray fluorescence (XRF). Lead was detected (concentration > 1 ppm) in 84% (n = 52) of the bone samples. The mean lead concentration of birds in which lead was detected …

Leygrain: A Participatory Action-Learning Model For Ley Pastures In Cropping Systems, D. L. Lloyd, B. Johnson, S. M. O'Brien
IGC Proceedings (1993-2023)
Since the 1930s, crop/pasture rotation systems have been used in the wheat-sheep belt of temperate southern Australia to maintain the productivity and environmental sustainability of farming systems (Puckridge & French, 1983). Yet, in the northern grain belt of Australia, there is limited adoption of ley pastures, owing to inherently fertile and well-structured vertisol soils. However, soil fertility decline now costs the grain industry about $450 m per year. Legume-based leys are an option for improving soil OM and N and providing other benefits to cropping and livestock production systems (Lloyd et al., 1991). Despite strong one-on-one extension processes since …

The frequency and severity of wildfire has increased around the world within the past two decades, due to shifts in land management practices, climate change, and other factors. The effects of these fires have led to an inaccurate public perception of wildfire as a whole. This overly-simplified, vilified perception of all fire obscures the role that it has played in shaping landscapes for thousands of years, and how indigenous peoples have applied fire to take care of landscapes.
Positive public perception of using fire as a tool for land management creates a more supportive environment for healthy landscape management. Thus, …

Seagrass Posidonia Escarpments Support High Diversity And Biomass Of Rocky Reef Fishes, Oscar Serrano Gras, Karina Inostroza, Glenn Hyndes, Alan M. Friedlander, Eduard Serrano, Caitlin Rae, Enric Ballesteros
Research outputs 2022 to 2026
Although seagrass meadows form a relatively homogenous habitat, escarpments, which form three-dimensional structures and originate from the erosion of seagrass peat, can provide important habitat for reef fishes. Here, we compare fish assemblages and habitat structural complexity among seagrass Posidonia australis escarpments and canopies, as well as limestone reef habitats, to understand the role of seagrass escarpments as reef fish habitat in Shark Bay, Western Australia. The total number of fish species, fish biomass, and top predator biomass were significantly higher in seagrass escarpments and reef habitats than in seagrass canopies due to lower habitat structural complexity and thus becoming …

Evaluation Of Oral Baits And Distribution Methods For Tasmanian Devils (Sarcophilus Harrisii), Sean Dempsey, Ruth J. Pyer, Amy Gilbert, Nicholas M. Fountain-Jones, Jennifer M. Moffat, Sarah Benson-Amram, Timothy J. Smyser, Andrew S. Flies
United States Department of Agriculture Wildlife Services: Staff Publications
Context
Diseases are increasingly contributing to wildlife population declines. Tasmanian devil (Sarcophilus harrisii) populations have locally declined by 82%, largely owing to the morbidity and mortality associated with two independent transmissible devil facial tumours (DFT1 and DFT2). Toxic baits are often used as a management tool for controlling vertebrate pest populations in Australia, but in other areas of the world, oral baits are also used to deliver vaccines or pharmaceuticals to wildlife.
Aim
Our goal was to evaluate the potential use of edible baits as vehicles for vaccine delivery to Tasmanian devils.
Method
We first tested bait palatability with …

Overlapping Scales Of Place Based Indigenous Knowledge And Hydroclimate In Australia, Rachel L. Coleman
Overlapping Scales Of Place Based Indigenous Knowledge And Hydroclimate In Australia, Rachel L. Coleman
Electronic Theses and Dissertations
Indigenous Peoples have been monitoring and adapting to uncertainty and change in their local regions for millennia, resulting in a holistic view of the interlinkages within the occupied complex socio-environmental systems. This research consists of investigating the overlapping scales of knowledge within Indigenous Australian seasonal calendars and colonial methods of hydroclimate assessment for improving adaptability to climate change impacts.
The analyses began with a sample of 25 Indigenous seasonal calendars providing a glimpse into interlinkages among biota, environment, and meteorology of the localised regions. Across the calendars, five themes of information and multiple categories within these themes became apparent and …
Reconstructing Deglacial And Holocene Climatic And Environmental Change In The Snowy Mountains Of Southeast Australia, Aidan Warner Burdick
Reconstructing Deglacial And Holocene Climatic And Environmental Change In The Snowy Mountains Of Southeast Australia, Aidan Warner Burdick
WWU Graduate School Collection
Multi-proxy, long-term records of deglacial and Holocene climatic and environmental change in southeast Australia are rare, leaving the region a gap in local and large-scale synoptic climate reconstructions. The Snowy Mountains include the highest and coldest regions of mainland Australia and were the only part of the mainland that was glaciated during the late Pleistocene. Lakes formed by the glaciers have provided continuous sediment traps since glacial retreat following the Last Glacial Maximum. In this report, I reconstruct the maximum ice extents of glaciers during the last glacial period and estimate their equilibrium line altitudes, revising the work of Barrows …
Vegetation Changes In Southeast Australian Temperate Grasslands, D. L. Garden, T. P. Bolger
Vegetation Changes In Southeast Australian Temperate Grasslands, D. L. Garden, T. P. Bolger
IGC Proceedings (1993-2023)
In temperate areas of southeast Australia, the combined effects of tree clearing, grazing, application of fertilizer and the introduction of exotic species have modified the original grasslands. This paper describes these changes and attempts to explain them in terms of ecological principles derived from North American grasslands. Stability of the original grasslands appears to have been due to the lack of disturbance and the slow rates of nitrogen (N) cycling within them. Increased N cycling after disturbance has allowed invasion of species better adapted to higher N status, particularly exotic annual grasses and weeds. The present composition of grasslands, in …

IGC Proceedings (1993-2023)
In the dairy region of northern Victoria, Australia, the performance of temperate perennial dairy pastures is often poor over summer due to a combination of high temperatures and limited water availability that can restrict dry matter production and plant survival. A series of field experiments examined the effects of heat and restricted irrigation (as a consequence of drought) on the growth and nutritive characteristics of selected forage species, and whether survival under experimental conditions was influenced by plant genotype, irrigation and grazing management strategies, as well as endophyte presence. The major focus was on perennial ryegrass.
Detailed sampling of perennial …

The Kimberley marine environment in Western Australia is widely recognised for its outstanding natural features, vast and remote sea and landscapes, and Indigenous cultural significance. To ensure that adequate baseline information is available to understand, monitor and manage this remote and relatively understudied region, scientific exploration was undertaken between 2012 and 2018 as part of the Kimberley Marine Research Program (KMRP). Whilst this program generated significant amounts of new knowledge about the region, important research gaps remain, that if answered, should improve the capacity of managers to conserve the region's values more effectively. Here, we apply established participatory horizon scanning …

Phosphorus Fertilizer And Stocking Rate Effects On Soil Microbial Biomass Of A Long-Term Dairy Farmlet Experiment, S. R. Aarons, C. R. O’Connor, C. J. P. Gourley
IGC Proceedings (1993-2023)
The effects of a range of P fertilizer rates and dairy cow stocking rates on microbial biomass carbon and phosphorus were compared in a long-term farmlet trial in southeastern Australia. Pastures were stocked at 2, 3, or 4 cows/ha and received fertilizer at rates of 0, 35, 70 or 140 kgP/ha. There was no effect of either P fertilizer rate or stocking rate on microbial biomass C from 1995 to 1998. Increasing P application rate significantly increased the chloroform-released microbial P flush measured, but stocking rate had no effect on microbial P. There were significant temporal changes, with the seasonal …

Groundwater Dependent Ecosystem Identification And Monitoring Protocols From Australia To California's Sustainability Groundwater Management Act, Marino J. Hernandez
Groundwater Dependent Ecosystem Identification And Monitoring Protocols From Australia To California's Sustainability Groundwater Management Act, Marino J. Hernandez
Master's Projects and Capstones
In the past, California’s unregulated groundwater supply has suffered from a legacy of groundwater depletion, loss of aquifer storage, land subsidence, seawater intrusion, and degradation of ecosystems dependent on the interconnectivity of groundwater. Prior to 2016, California had yet to create direct legislation that regulated groundwater management until the Sustainable Groundwater Management Act (SGMA). SGMA empowered local agencies called Groundwater Sustainability Agencies (GSAs) to manage groundwater resources within a specific criterion using locally sourced methods and practices suitable for each individual groundwater basin.
