Natural Capital RestorationProject
• Eurostat-funded project
• Work supported by NCC *
• Began 2016 – completed October 2017
• Two objectives:
1. Roadmap - re. register of Nat. Cap. , value lost
over time and cost to restore
2. Two pilot studies – to show applications & issues
* ‘Restoration efforts, therefore, need to be sustained and underpinned
by long term commitment’; and
‘An estimate of the potential restoration costs to maintain natural
capital is essential and the committee is firmly of the view
that this needs to be calculated as part of the
national natural capital accounting framework.’
(NCC, 2014; Helm, 2014)

Where does restorationfit in?
Restoration: ‘the process of assisting the
recovery of an ecosystem that has been
degraded, damaged or destroyed’
(SER, 2004)
Restoration effects over time

Where does restorationfit in?
‣ ‘Actual’, ‘business as usual’ (bau) accounts
with parallel
‣ ‘Hypothetical’, restoration-based accounts
for comparison
8.
Ecosystem condition- ecosystemservices &
restoration/maintenance/neglect
Ceteris paribus, Condition (lhs) → Services (present)
and, depending upon management (restoration/maintenance/neglect),
→ Services (future)
Key: Right-hand graph lines show ES flow following different starting condition
categories from left-hand graph. RHS: Black curves/lines – business as
usual (bau); thick dotted lines – restoration; fine dotted lines –
maintenance; grey curve – ES unsustainably extracted.

Ecosystem condition- ecosystemservices – thresholds and
tipping points
Threshold: “The point at which (below which) the decline in status accelerates and/or
becomes difficult to reverse.
A discontinuity whereby a small change in a driver exerts the largest change in an
attribute or state of an ecosystem, typically abrupt.” (NCC, 2014b) .
Tipping point: “a point at which an (ecological) system experiences a qualitative
change, mostly in an abrupt and discontinuous way” (Jax, 2012)
See grey dotted line on previous slide.
Beyond this point, restoration may not be feasible/economically justified
10.
Ecosystem restoration –what are we aiming for?
The target level (the level for which we are aiming)
may be based on some reference point (some
past level)
Reference point ranges from ancient past
(pristine?) to the start of the current period

Ecosystem condition- andmultiple ecosystem services
As degradation/restoration takes place, the patterns of the different ES may differ
12.
Ecosystem condition- andmultiple ecosystem services
ES Possibility Frontier (ESPF)
The frontier shows the capacity of the
ecosystem in terms of the different
combinations of ES possible given the current
condition (discounted service flows). X and Y show 2
possible combinations. Inside curve shows technically
inefficient outcomes
Corner solution possible
(and even negatives
possible [e.g. GHG
emissions])
As condition
improves, ESPF
moves out –
showing larger
combinations of ES
But ESPF may not
move uniformly
with improving
condition. (optimum
combination I may not
be more of both vis a
vis point H)

Restoration activities andcosts
Types of activities and costs:
• Initial investments/up-front costs
• Ongoing costs
• Managing and monitoring costs (should
monitoring costs be applied?)
• Periodic maintenance & harvesting costs
• Opportunity costs (only in terms of
Cost:Benefit Analysis?)
14.
Restoration activities andcost information
Cost estimates:
• Substantial number of published sources
• Range from review studies to ‘manuals’
But
• Not all ecosystems
• Less on actual costs
• May not be publicly available (archived, private business, accounting system doesn’t
separate, not published)
• Often not disaggregated
• May be averages only
• Grant rates – proxy for costs to operator
• Timings rare
• Some ‘broad brush’

detailed annexes

Pilot study 1– Exmoor Mires Partnership
• Aim: to restore degraded peatland and vegetation
• ES - GHG, water quality, flood prevention, biodiversity,
grazing, recreation
• Since 2006 3000 ha.

(local involvement), influence policy.
• ES – GHG, flood prevention, biodiversity, grazing,
recreation, education
• Since 1999 5300 ha. vision

Where do restorationcosts fit in
ecosystem accounts?
Actual or hypothetical?
• UN (2003) and Mayer (2013)
- use restoration costs if restoration is underway
- if not, use restoration costs if this is less than the NPV
•UN (2012) and Technical Rec. (2017)
- only use restoration costs if restoration is underway
- otherwise, parallel accounts can be produced to
compare bau with restoration
Conclusion:
• More work and discussion needed
• Useful with accounts either way
24.
Issues
• Ecosystem condition- ecosystem services - restoration activities links
• Restoration costs information.
• Monitoring of ecosystem services
• Scaling up is possible, but uncertainty -insufficiency of data.
• Time
• Ecosystem accounts and restoration costs
• The quality of the planning and implementation of policies
• People should be central
25.
Restoration costs -recommendations
Better understand:
ecosystem condition,
ecosystem services, and
restoration activities (& other influences)
Establish database – ONS/Defra, Eurostat
Scaling up – asset & risk register
- acknowledge uncertainty, improve over time
Ecosystem accounts – restoration costs
- in parallel or mainstream? (and what about disservices?)
Time!
Also
Better policy (& sociocentric)
`
Collaboration
Asset and riskregister
• Parallel with NC Roadmap
• Based on ‘value’, ‘risk’ (asset quality and direction of
change), and ‘facility’ (availability and ease of obtaining
data)
• 4 key elements:
– Overview/reviews
– Broad habitat coverage
– Database (& guidelines)
– Overall UK asset and risk register
• Overall coverage, but may need to focus - target
Restoration costs –what next?
What to publish from this work?
Roadmap for asset and risk register
- linked to NCA work
- focussing where high ‘value’/‘risk’/ ‘facility’
Eurostat funding facilitates work on MMH &
peatland
Work can begin on a database and guidelines
How much progress is made will depend on
funding support – is it worthy?
31.
Conclusions
• Project objectivesmet - two pilot studies* & roadmap completed.
* restoration seems worthwhile
• A national (and European) database bringing together restoration, ES
and state of ecosystem data from disparate sources is recommended.
• ONS and Defra to lead in putting the roadmap into effect (parallel to NCR)
• Time - wide range of implications - must be woven into thinking about
ecosystem restoration.
• Ecosystem accounts - restoration costs - supplementary information or a
place ‘mainstream’ accounts . Further debate is needed (& on disservices too)
• Restoration policies need careful design and implementation (with
agency collaboration and good stakeholder engagement - losers as well as winners
considered). The CAP and Brexit provide opportunities.
• Progress can be made on habitat-based, asset and risk registers and
database to 2020+ - with collaboration and support
