The Glenelg Hopkins Natural Capital Region covers the Victorian coast from Warrnambool to the South Australian border and north to the Grampians. The region includes the catchments of the Hopkins River discharging at Warrnambool, the coastal streams to Portland and the Glenelg River. The area is mostly cleared or natural open plains (as part of the Victorian Volcanic Plains) and is dominated by grazing and dryland cropping. The Rocklands Reservoir is a major water storage in the upper Glenelg River. The area is known for its scenic beauty along the Southern Ocean. The region stretches 160km north to south and 250km east to west.

Explore the current condition in the interactive condition report below – Click on a sub-catchment to view a report on the natural capital measures for that sub-catchment in the ‘report’ tab.
Choose the natural capital measures that are important to you – Select the ‘hotspot’ tab and check the indicators that are important to you. Then view measures that are aggregated and range standardised from the highest to the lowest value across the sub-catchments (red for worst and blue for best). By simultaneously considering multiple natural capital measures you can instantly see where the greatest opportunities for natural capital improvement are.
One of the most common uses of Natural Capital Region is to prioritise what to do and where to do it and to forecast the future natural capital condition under alternative nature repair investment programs.
The rapid scenario creation and running allows for the development of co-operative investment strategies that include the priorities of multiple partners (e.g. NRM organisations, federal government, state government and local government).
To facilitate this rapid scenario generation, Natural Capital Region includes region-specific libraries of tens of possible on-ground actions. Each action includes their effectiveness for improving natural capital outcomes, the cost per hectare of the action and the likelihood of adoption of each action.
To demonstrate, a simple investment scenario is embedded below.
| Budget: | $50,000,000 |
| Area: | All sub-catchments |
| Positive Actions: | Terrestrial and riparian revegetation nature repair and conservation actions (protecting remnant vegetation and native revegetation replanting) |
| Negative Actions: | Do not consider the implications of negative actions (e.g. excluding impacts of ongoing clearing or urban expansion) |
| Maximum area per sub-catchment: | Set the maximum area for each action per sub-catchment as 10% of the available area for that action (spread the investment across several actions) |
| Adoption likelihood: | Use likely landholder adoption rates (includes total proportion of landholders and time to achieve adoption) |
| Priorities: | Prioritise based on biodiversity and carbon sequestration outcomes Include economies of scale to favour actions in catchments where there is high availability of land to do the actions |
Explore the scenario results spatially – Click sub-catchments on the map to see the cost breakdown over time and by sub-catchment.
Explore the marginal cost abatement – This shows where the rate of improvement vs cost starts to flatten off. Hover over the chart to see a breakdown of each suggested action by sub-catchment with the associated co-benefits of the action quantified.
Natural Capital Region forecasts a potential future state by considering alternative on-ground actions. A critical step in this process is compiling the data to establish the baseline condition for the region.
Metadata for the indicators (and groupings used in Action set up) included in the Glenelg Hopkins (Victoria) instance of Natural Capital Region have been thoroughly documented.
