Environmental interpretation, a widely accepted approach to communicating with tourists in North America, Latin America and the U.K., is based on communication research undertaken mainly by researchers in western cultures or focused on Anglo-Saxon audiences. This project advances theory and practice by critically examining the relevance of this model for communicating with visitors from a range of cultural backgrounds. Environmental messages, communication media and the application of environmental interpretation principles are experimentally manipulated to evaluate their relative effectiveness in communicating with international and domestic visitors from culturally and ethnically diverse backgrounds, as a basis for refining the model for wider application.Read moreRead less
Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance ....Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance of nutrient uptake by plants. The effects of the developed method on nutrient use efficiency and leaching loss, and crop yields will be quantified under different soil types and climatic conditions.Read moreRead less
Fostering pro-environmental behaviour of zoo visitors through strategic communication. A key part of achieving an Environmentally Sustainable Australia is to change human behaviour. Given annual visitation to Australia's zoos of 14.5 million, including about 4.2 million to the partner organisations, there is great potential for zoos to use their experiential platform to foster pro-environmental behaviour. How best to persuade people to change their behaviour, however, is still poorly understood ....Fostering pro-environmental behaviour of zoo visitors through strategic communication. A key part of achieving an Environmentally Sustainable Australia is to change human behaviour. Given annual visitation to Australia's zoos of 14.5 million, including about 4.2 million to the partner organisations, there is great potential for zoos to use their experiential platform to foster pro-environmental behaviour. How best to persuade people to change their behaviour, however, is still poorly understood. This research will improve the capacity of zoos to achieve pro-environmental behaviours among their visitors and thus have significant environmental and social benefits. Linking motivational factors with visitors' susceptibility to persuasion will assist any organisation that seeks to foster pro-environmental behaviour.Read moreRead less
Building capacity for adaptive management in protected areas through improved systems for monitoring and evaluation. The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow mana ....Building capacity for adaptive management in protected areas through improved systems for monitoring and evaluation. The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow managers to better allocate resource for more effective conservation outcomes. The project establishes connections with all protected area management agencies in Australia, and will contribute to the development of national policy and practice in protected area evaluation and reporting, thus helping to meet national and international reporting obligations.

New strategies to save the Critically Endangered plant Grampians Pincushion Lily (Borya mirabilis, Liliaceae/Boryaceae) from extinction. The Grampians Pincushion Lily (Borya mirabilis) is Critically Endangered (only 7 remain). Efforts to increase its population and range and maintain or enhance its genetic diversity by standard methods have had only modest success so far. The aim of this proposal is to create more innovative methods in a deeper, more research-based approach to solving these ....New strategies to save the Critically Endangered plant Grampians Pincushion Lily (Borya mirabilis, Liliaceae/Boryaceae) from extinction. The Grampians Pincushion Lily (Borya mirabilis) is Critically Endangered (only 7 remain). Efforts to increase its population and range and maintain or enhance its genetic diversity by standard methods have had only modest success so far. The aim of this proposal is to create more innovative methods in a deeper, more research-based approach to solving these problems by using greater knowledge and understanding of its biology and reproduction. In particular, plant tissue culture and molecular biology will allow us to devise more effective approaches and potentially create methods that could be applied to other endangered species, particularly Borya and its relatives.Read moreRead less
The impact of high kangaroo populations on regeneration of arid woodland tree species. Remnant arid woodland in south-eastern Australia is threatened by regeneration failure resulting from high grazing pressure from sheep, rabbits and kangaroos. Elimination of sheep grazing, reduction in rabbit populations as a result of RCD and a decision to cull kangaroos has provided an unprecedented opportunity to ascertain the impact of kangaroos on regeneration, in particular the degree to which kangaroos ....The impact of high kangaroo populations on regeneration of arid woodland tree species. Remnant arid woodland in south-eastern Australia is threatened by regeneration failure resulting from high grazing pressure from sheep, rabbits and kangaroos. Elimination of sheep grazing, reduction in rabbit populations as a result of RCD and a decision to cull kangaroos has provided an unprecedented opportunity to ascertain the impact of kangaroos on regeneration, in particular the degree to which kangaroos put a selective pressure on seedlings of overstorey species. Research proposed in association with Parks Victoria, will make a major contribution to understanding of the need for active management of remnant woodlands and assist in the preservation of significant communities.Read moreRead less
Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the ....Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the project will enable water planners to manage their urban water systems efficiently and effectively under a range of long term and short term planning conditions including droughts, while reducing associated environmental impacts.Read moreRead less

The development and application of technologies and knowledge for enhancing sustainable management of semi-arid environments are of high priority and significant economic, social and environmental benefit. The value of iron ore exports from the Pilbara is expected to grow by nearly 30% in the next year, while the projected production of iron ore over the next 4 years is expected to be valued in excess of 60 billion dollars. However, continued and rapid expansion in the development of these resources is contingent on environmental oversight and adoption of an adaptive management approach. This research will thus make a major contribution to understanding the Pilbara ecosystems that provide tremendous economic wealth for all Australians.Read moreRead less
Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries. Old quarries are increasingly used for the construction of landfills. The engineering challenge in constructing such landfills includes developing an appropriate lining system for the often steep sided quarry walls. The use of GCLs as part of the lining system can be a viable and a cost effective solution. However, this solution suffers from the lack of meaningful data on ....Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries. Old quarries are increasingly used for the construction of landfills. The engineering challenge in constructing such landfills includes developing an appropriate lining system for the often steep sided quarry walls. The use of GCLs as part of the lining system can be a viable and a cost effective solution. However, this solution suffers from the lack of meaningful data on their hydraulic durability in this particular situation. This proposal presents an original approach to investigate this durability under operating conditions typically encountered in steep sided quarries. This work is expected to provide benefits to waste containment efforts at national and international level.Read moreRead less
