“A Natural Investment”Using a case study approach:
1. What is the investment needed for large scale protection and restoration of habitat?
2. What are the returns on this investment?
• What are the area targets?
• What are the costs of “restoration”?
• What is the return from carbon?
• What is the impact of change of land use?
• What impact on regional economic activity?
![Page 4: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/4.jpg)
Why are we doing this?
• There is a crisis in the health of Victoria’s biodiversity
![Page 5: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/5.jpg)
Threatened species
Victoria:
44% native plants, and
30% of native animals extinct or threatened
![Page 6: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/6.jpg)
Landscape stress
Stress index includes:
Vegetation clearing
Lack of water
Salinity
Pests and weeds
Threatened species and ecosystems
Highest stress
Lowest stress

Native vegetation types pre-1750
![Page 8: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/8.jpg)
Native vegetation types in 1987
![Page 9: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/9.jpg)
The need for action:
Science [1] tells us to implement ‘connectivity conservation’ including:
• Protecting remnant vegetation
• “Restoring” the quality of the veg
• “Connecting” the remnants
[1] E.g. Mackey, B. et al, 2010, Connectivity conservation and the Great Eastern Ranges corridor. Independent report to the Interstate Agency Working Group. And many others.

The White Paper on land
and biodiversity:
Nossal: “Time for business as usual is over..”
Requires: “..a significant increase in shared investment, action and
cooperation over the next 50
years or more” (DSE, 2009, p15).

The case study:
The Victorian section of Habitat 141 south of Big Desert
![Page 12: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/12.jpg)
Habitat 141: Outback to the ocean
![Page 13: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/13.jpg)
![Page 14: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/14.jpg)
Why this area?
• Has restoration targets for 30 years
• Has costs of restoration
• Has data on carbon revenue
• Has economic activity stats
![Page 15: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/15.jpg)
Answers needed to: • What investment is needed to achieve
restoration targets?
• What returns on investment?• $ - carbon; maybe some ecosystem services
• Unpriced benefits - resilient biodiversity, unpriced ecosystem services, amenity etc
• What economic development?
• Diversified farming
• What impact on regional economic development?
• Where will $ come from: private and/or public funds?
![Page 16: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/16.jpg)
Restoration targets :
Total of 255,000 ha on private land:
– 150,000 ha for biodiversity restoration
and carbon; on farming land
– 62,000 ha of biodiversity restoration with no carbon counted; on farming land
– 42,000 ha “landcare” plantings for bio’y; no carbon counted; on land not farmed
![Page 17: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/17.jpg)

Investment needed:
1. Restoration costs for 255,000 ha over 30 years:
$333 million
2. Cost of securing land for biodiversity/carbon for
all land except the “landcare” plantings, ie
212,000 ha, based on current agricultural value
of land: $114 million
TOTAL: $447 million over 30 years
![Page 19: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/19.jpg)
Revenue:
Only from carbon storage
- on 150,000 ha;
- at a constant $25/tonne
Total over 30 years: $176 million
($2010. A real discount rate of 5% per annum was used - in line with guidelines of Vic Treasury and Finance)
![Page 20: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/20.jpg)

Overall investment and
returns:• Costs over 30 years:
– $447m total includes:• $333m – restoration costs
• $114m – to secure protected status eg purchase.
• Revenue:– from carbon @ $25/t = $176m– from carbon @ $60/t = $450m
NOTE: still have the land as an asset
![Page 22: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/22.jpg)
Aust Treasury and C prices:
– $35 - $50 / tonne by 2020
– $115 - $158 / tonne by 2050
So whole program becomes profitable between 2020 and 2030

URS consultants:
Modelled the impact of:
• achieving the targets
• impact of the changing land use on farming
land
– Direct and indirect employment
– The regional economy

The results
REGIONAL ECONOMIC IMPACT over
30 years:
• Reduces net regional income by
less than 0.5% of the gross value
of agriculture in the area
![Page 27: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/27.jpg)
The results - jobs
• Restoration jobs provide small
positive jobs outcomes - 37 new jobs.
• NOT a loss of jobs.
• Jobs in rural areas not just regional
centres.
![Page 28: The Victoria Naturally Alliance is led by the Victorian ...](https://reader031.fdocuments.in/reader031/viewer/2022012515/618e7b0b3d94856cd44f016f/html5/thumbnails/28.jpg)
Unpriced benefits include:
Ecosystem services
Reduced salinity
Increased agricultural productivity
Improved amenity
Ecological resilience - system can still
support agriculture, communities etc.

Where to?
• Promote and seek feedback
• Extend to rest of Victoria
• Develop major package for Victoria
• Ensure the biodiversity component is
part of the carbon farming
• Suggestions welcome
