KEY ISSUES
• Integrating management across ecosystem services by: re-establishment of the Lower-Goulburn River floodplain; alternative revegetation strategies; and nutrient management including the merits of alternative approaches.
• Managing land-use intensification.
• Managing transitions in land-use.
• Managing vegetation for the full suite of ecosystem services.
• Managing cultural, heritage and option values.
• Maintaining soil health.
• Accounting for the value of non-agricultural land and water-uses.
• Water and salinity management.
• Anticipating and adaptively managing emerging issues.

ECOSYSTEM SERVICES FROM DAIRY
• Output– Dynamic model of milk producing area on a dairy farm with
emphasis on ecosystem services
• Results– Greatest variation between dairy management practises is in
feed supplementation and water use efficiency
– Water re-use systems on high input farms increase milk production and reduce nutrient runoff
– Higher herd productivity through the provision of shade and shelter
![Page 8: THE ECOSYSTEM SERVICES PROJECT](https://reader035.vdocuments.us/reader035/viewer/2022062309/568142bc550346895daf006d/html5/thumbnails/8.jpg)
ECOSYSTEM SERVICES ON THE FLOODPLAIN
• Output– Spatially explicit dynamic model for generation and evaluation
of future management options
• Results– Floodplain is highly interconnected system – model shows
complexity, key drivers and trade-offs
– Improved management of river flows has implications for a suite of other services
– Extremely long time scales are involved in the vegetation change (Hab. Ha. Score) and therefore management process
![Page 9: THE ECOSYSTEM SERVICES PROJECT](https://reader035.vdocuments.us/reader035/viewer/2022062309/568142bc550346895daf006d/html5/thumbnails/9.jpg)
ECOSYSTEM SERVICES FROM VEGETATION PATTERNS
• Outputs– A GIS model that shows changes in various ES’s as vegetation
cover changes
• Results– Benefits of shelter belts peaks at 40% native veg cover
– Erosion rates much lower under native veg
– Water yield to channel is affected by spatial configuration of veg
– Water yield to deep drainage is sensitive to the area of deep rooted perennials

ECOSYSTEM SERVICES AND ECONOMY AT CATCHMENT SCALE
• Outputs– Input output model that tracks dollars, water and nutrients
among 33 sectors of the GB economy
• Results– Dairy processing industry has largest influence on economy
– ‘Other horticulture’ has largest influence on water use for each dollar invested in industry
– Simultaneous evaluation of investments in regulation of river flows, stream health etc. and importance of industries

FINAL STEPS
• Sensitivity Analysis
– uncertainty of impact data and weights
– test sensitivity of outcomes for most crucial and contentious criteria and impacts.
• Reiterations
