About

My research broadly focuses on catchment water quality in northern Australia, particularly the role of anthropogenic stressors in aquatic communities. One key area of interest is in identification of progressive agricultural practices that offer improvements from a natural resource management perspective to industry, while also ensuring the long-term social and economic viability of farming enterprises. I am also interested in better quantifying the temporal and spatial extent of water quality contamination in coastal freshwater and estuarine wetlands, particularly with regard to chronic, sub-lethal exposure to pollutants.

Other areas of research interest broadly include fish ecology, particularly size-related trophic ecology and the evolutionary processes influencing the present-day Australasian fish fauna. This includes the biogeographic, phylogenetic and paleoecological drivers that have shaped the unique contemporary fish assemblage structure evident in Australian freshwaters. Other research interests include landscape ecology in relation to wetland connectivity, and the identification of primary production sources for aquatic communities and relationships to flow regime (i.e. dietary and isotopic ecology).

Sugar Research Australia - Research Grant

Keeping our chemicals in their place - in the field

Indicative Funding
$55,602 over 5 years (administered by Sugar Research Australia)
Summary
The study assesses on-farm management practices in relation to minimising off-farm losses of pesticides in the Australian sugar industry. The study will involve a series of integrated short-term and long-term paddock-scale studies of pesticide movement in runoff to identify best management practices for pesticide management.

'Project 25' - farmers, water quality and on-farm decision-making

Indicative Funding
$400,000 over 3 years
Summary
Landholder concerns surrounding the credibility of broad-scale water quality monitoring and modelling initiatives in the GBR catchment area are one of the key cane industry engagement challenges for promoting significant farming practice change, and water quality improvements. Based around small, sub-catchment water quality monitoring in a key GBR cane growing region, Project 25 utilises a bottom-up approach to integrated sub-catchment monitoring and intervention to identify 'hot spot' sub-catchments through localised water quality monitoring. The Project emphasises industry ownership and control of monitoring design, and delivery of locally targeted water quality data and extension effort to facilitate practice change.

Project 2016002 - Protecting our chemicals for the future through accelerated adoption of best management practice

Indicative Funding
$39,000 over 2 years
Summary
A collaborative project with Sugar Research Australia to identify appropriate management strategies for pesticides to maximise efficacy while minimising pesticide losses off-farm. Key JCU-TropWATER roles in project include: 1. Expert interpetation of water qulaity data sets generated through rainfall simulation and other water quality monitoring activities. 2. Advice on experimantal design and planning 3. Assistance in running rainfall simulation and water quality monitoring activities as required. 4. Assistance in communication of results and water quality issues, including presentation and discussion with growers.

Engaging with farmers and demonstrating water quality outcomes to create confidence in on-farm decision-making ("Project 25")

Indicative Funding
$460,000 over 3 years, in partnership with the Department of Environment and Heritage Protection ($21,500)
Summary
Recent global experiences suggest that spatially identifying and prioritizing landscape `hotspots? of pollutant generation for management intervention, and small catchment-scale water quality monitoring in collaboration with landholders linking water quality with specific management practices, are among the most promising strategies for reducing water quality pollution. This project will combine recent hotspot identification in GBR sugarcane catchment of the Russel/Mulgrave with targeted cane farmer interaction activities (related to sub-catchment and localized monitoring activities), focusing on emerging monitoring technologies (real-time water quality monitoring) to link farmer on-farm practices with feedback from sub-catchment water quality measurements. The use of both scientific and citizen science monitoring approaches will deliver robust feedback loops to enable farmers to directly link their activities with water quality conditions. The project will focus on on-farm practice improvements in highest priority catchments to achieve maximum benefits to GBR health from catchment management actions.

Sub-catchment scale monitoring, modelling and extension design to support reef water quality improvement

Indicative Funding
$100,000 over 2 years (administered by Reef and Rainforest Research Centre)
Summary
This project aims to develop a sub-catchment scale water quality monitoring program in key cane growing catchments to provide more refined spatial and extension targeting of management action change to reduce nutrient and pesticide runoff from cane areas in order to meet GBR Reef Plan targets. The project will be developed in two key catchments, with a small pilot component to provide 'proof of concept'. The subsequent plan will provide the template for GBR catchment wide water quality monitoring by government agencies.
