Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less
New methods for mapping variation in forest water use in time and space. Disturbance of eucalypt forests can have dramatic impacts on catchment water yields. In partnership with Melbourne Water Corporation, this project will develop and test new methods for accurate mapping of variation in water use across forested water supply catchments and for accurately determining the effects of this on water supplies.
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.

Marine urban development: how can ecology inform the design of multifunctional artificial structures? This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives. Artificial structures such as buildings and roads have featured in terrestrial urban landscapes for many years, but have only more recently begun encroaching on aquatic environments. Most marine artificial structures lack the innovative design solutions required to mi ....Marine urban development: how can ecology inform the design of multifunctional artificial structures? This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives. Artificial structures such as buildings and roads have featured in terrestrial urban landscapes for many years, but have only more recently begun encroaching on aquatic environments. Most marine artificial structures lack the innovative design solutions required to mitigate their ecological impacts and provide essential ecosystem services such as pollution abatement. This project will investigate the efficacy of these designs with both classical measures of diversity and structure and novel measures of ecosystem function. The project aims to provide essential information to inform the design of future marine urban developments.Read moreRead less
The trophic ecosystem of a purpose-built, offshore artificial reef: do coastal currents supply sufficient nutrients for the local production of fish? Offshore artificial reefs may provide enhanced recreational fishing for an urbanized coast. This project will investigate the oceanographic and ecological processes around the new, design-specific, reefs off Sydney to determine if they actually produce fish, rather than simply attract fish. The project will influence the design of future reefs.
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
Methane and nitrous oxide in agro-ecological systems: novel technologies and understandings to improve ecosystem management. Methane and nitrous oxide are critical greenhouse gases but globally we lack ecosystem scale analyses of the balance of emissions, including animal emissions, and soil oxidation. This project will quantify this balance for a range of agro-ecosystems, and explore and develop opportunities for improving soil-based Greenhouse Gas (GHG) mitigation measures.
