This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ability to adequately predict spread. New models that combine micrometeorological measurements, within-canopy turbulence and topographic variation in wind flows will be designed to better predict where dispersal will occur. In this project, these improved predictions are planned to be combined with decision models to direct the management of invasive species across entire landscapes.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
Building resilient alpine environments with less snow. In this project, we aim to build resilience into alpine National Parks and Alpine Resorts to counter the effects of ongoing declines in snow. Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning. How these processes will operate in a snow-free future is unknown. We will determine how and where snow characteristics drive soil water availability for plant ....Building resilient alpine environments with less snow. In this project, we aim to build resilience into alpine National Parks and Alpine Resorts to counter the effects of ongoing declines in snow. Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning. How these processes will operate in a snow-free future is unknown. We will determine how and where snow characteristics drive soil water availability for plants and which plant species have the best adaptation and regeneration potential under extreme conditions such as heat, frost and drought. Benefits of the project include innovative land management and rehabilitation solutions, to safeguard Australia's alpine areas under changing environmental conditions.Read moreRead less
Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, ....Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, contaminating water supplies and damaging critical infrastructure. The capacity to mitigate the risk of interruption to the water supplies of our cities and towns in a more fire-prone future is currently limited by our knowledge of where, why, and how often these post-fire contamination events will occur. This project aims to address these knowledge gaps.Read moreRead less
How does orography enhance precipitation in Australian wintertime storms?

This project aims to employ targeted field observations, numerical simulations and new satellite capabilities to identify the dynamical and microphysical mechanisms that enhance and redistribute precipitation across the alpine regions of south eastern Australia and Tasmania. These observations will be used to evaluate operational numerical weather simulations specifically focusing on quantitative precipitation forecasts and estimates. The observations will also be used to extend known biases in the national gridded precipitation analysis that are a result of the complex mountain terrain. This identification of the physical processes that enhance and redistribute precipitation over the alpine regions across south east Australia and Tasmania will lead to better precipitation estimates and forecasts and better water management.Read moreRead less
