This project is undertaking acid sulfate soil risk mapping in priority areas from Bowen in the north to Miriamvale in the south.
Mackay Whitsunday NRM region
This activity is part of the Douglas WQIP project # 5 – Monitoring and Modelling of Sediment and Nutrient Flow Within and From Waters of Douglas Shire.
This project has gathered data from the automatic, manual and community monitoring activities so that it is stored, can be viewed and downloaded from the web.
Monitoring and modeling information will underpin establishment of a decision-support system (DSS) for environmental protection and planning activities in the Douglas Shire. The DSS tool will play a valuable role in environmental and planning decision- making, by assessing land use change on pollutant generation at the stream reach level and providing a tool for priority setting and investment planning at the expert, manager and community user scale to achieve agreed water quality targets. Outcomes: A data management and desktop data delivery system for Douglas Shire has been completed. The system is currently operational and is using CSIRO infrastructure. The interim URL is www.data-tv.csiro.au/DSCDDD/index.aspx The water quality data is visible and available to both internal and external users.
The program is led by the Mackay-Whitsunday Natural Resource Management Group, with the goal to ensure Healthy Waterways in the Mackay-Whitsunday region. The program aims to cooperatively deal with threats and opportunities associated with the “health” of rivers and streams within the region. The programs objective is to have rivers and streams in the region that is able to sustain a high diversity of environmental, economic and social activities. The overall program is made up of: Information Collation and Analysis, Industry Management and Practice – Urban / Industrial / Agricultural, Monitoring, Research and Development.
“This project will sample and assess the contemporary fertility of typical surface soils from sugar and horticultural lands in sensitive reef catchments. This information will be interpreted in the context of land use, resource condition and trend and current fertiliser and by-product use practices with the emphasis on evidence of need to improve nutrient management practices and avoidance of overuse. Outcomes: • Collation and circulation of soil test diagnostic criteria for levels separating fertiliser response from non-responsive sites
• Assessment of hillslope erosion risk
• Documentation of laboratory methodology for inclusion in to the Australian • Handbook of Soil Chemical Methods
• Survey of findings by crop, catchment and region
• Assessment of the usefulness of ‘traditional’ soil P tests and the Mehlich 3 for predicting soluble P”
The objectives of this research are to:
– Make robust estimates of terrestrial inputs of nutrients and sediment to the Great Barrier Reef World Heritage Area (GBRWHA) which appropriately weight the relative contributions of wet, dry, pristine and modified catchments.
– Resolve short-term biological and chemical processes in Great Barrier Reef (GBR) waters which influence the biological availability and uptake of nutrient materials (carbon, nitrogen, phosphate) in river plumes.
– Develop an improved estimate of the fate of nutrient materials (C, N, and P) delivered to shelf sediments as a result of land runoff and related biological production, with emphasis on nutrient burial, recycling and denitrification in nearshore (terrestrial) sediments.
– Use the above information and other appropriate field and historical data, to develop robust, closed models and budgets of nutrient inputs, processing and fates as a basis for comparing human-influenced and pristine shelf regions in the GBRWHA.
– Provide environmental and water quality data essential to the companion task (22.214.171.124): effects of terrestrial run-off on coastal reefs.
– During the course of the above, to maintain long-term water quality monitoring activities in representative sections of the central GBR.
– To provide reef managers and users with timely and appropriate information to assist them in the management and conservation of nearshore reef systems, particularly with respect to the management of enhanced terrestrial run-off.
