A Cost-Effective System for Monitoring Lightning Strikes Across Australasia. Lightning causes many major fires in Australia, and rural fire managers would benefit from access to lighting data. Lightning data have been prohibitively expensive because acquiring them requires a dense monitoring network. Low Frequency Electromagnetic Research Ltd (LF*EM) has developed an alternative, cost-effective technology for monitoring lightning based on a sparse network of stations monitoring VLF radiation. We ....A Cost-Effective System for Monitoring Lightning Strikes Across Australasia. Lightning causes many major fires in Australia, and rural fire managers would benefit from access to lighting data. Lightning data have been prohibitively expensive because acquiring them requires a dense monitoring network. Low Frequency Electromagnetic Research Ltd (LF*EM) has developed an alternative, cost-effective technology for monitoring lightning based on a sparse network of stations monitoring VLF radiation. We propose to translate LF*EM's basic science results into a product that can deliver lightning data to fire managers and other users across Oceania.Read moreRead less
Simulation Technology for Modelling Extreme Bushfire Behaviour. Extreme fires cause immeasurable damage to communities through destruction of homes and damage to infrastructure. Large, highly intense fires reduce biodiversity, take decades for recovery, increase greenhouse gas emissions and reduce carbon storage capacity. Climate change is likely to increase the frequency of extreme fire weather increasing the need for reliable fire spread prediction under extreme conditions and to reduce impa ....Simulation Technology for Modelling Extreme Bushfire Behaviour. Extreme fires cause immeasurable damage to communities through destruction of homes and damage to infrastructure. Large, highly intense fires reduce biodiversity, take decades for recovery, increase greenhouse gas emissions and reduce carbon storage capacity. Climate change is likely to increase the frequency of extreme fire weather increasing the need for reliable fire spread prediction under extreme conditions and to reduce impact by preparedness and suppression. Incorporating an evidence-based fire spread model into a fire location forecasting system will give fire agencies early warning of potentially disastrous fires, enable early response to prevent fires and mitigate the consequence to life, property and the environment.

Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less
Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of popula ....Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.Read moreRead less
Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for s ....Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for shrubland vegetation types. It offers advances in our understanding of ecosystem structure and function, with applied value in fire management for conservation and asset protection. The project contributes to development of ecological theory, and provides a scientific basis for improved management of Australia's unique natural heritage.Read moreRead less
Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental b ....Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental benefit. The opportunity to conduct experimental fires across a complex landscape will enable calibration and development of technologies not previously possible. This research will define the way prescribed fire is used to integrate young rehabilitated forest into management of the broader landscape and develop more cost-effective tools for fire management.Read moreRead less
