3.1 Introduction
What threats and risks can be avoided to improve the
chances of success of a restoration effort? What are the
temporal, spatial, qualitative and quantitative factors that are
most important when assessing risk factors? One approach
is to be aware of what has caused significant problems in
other projects and to ensure that the same compromising
factors are accounted for in the planning and design
stages. The limitation of this approach is that there is no
specific set of risk factors that will be present for every
project, as each restoration site and project have their own
unique set of circumstances. For example, in the case of
ship groundings on reefs, there can be unique factors that
need to be addressed which are characteristic of ship
impacts, like the production of large volumes of rubble and
the presence of potentially toxic anti-fouling paint1-3. It has
been suggested that in reef systems where there is
evidence of a high rate of natural coral recruitment,
allocating limited resources to managing the most obvious
sources of disturbance may be a better approach than
active rehabilitation, leaving natural regeneration processes
to restore the damaged reef4-5.
Previous rehabilitation projects (including some of the case
studies presented in Chapter 8) show that the range of
issues that can negatively influence the success of a project
are numerous and diverse. Many of the adverse factors that
come into play are unexpected6 or not adequately
accounted for in the initial planning stages or in the project
design. It is clear that some of these negative influences
could have been considered in the planning stages (during
scoping and choice of site) if a more rigorous risk
assessment had been carried out.
This chapter formalizes the lessons learnt from past studies,
by presenting a structured approach and relatively simple
assessment protocols so as to minimise risks in future
projects. If you undertake effective risk management at the
planning stage, and incorporate appropriate responses to
the perceived risks in your project design, you should have
a better chance of success than many projects in the past.
3.2 Overview of risk assessment
At the outset of the risk assessment process, it is
necessary to distinguish between locally manageable risks
(local human impacts), and externally derived threats to
project success that cannot be managed locally.
Nonetheless, threats that are external to a project’s
immediate influence (e.g., global climate change7, tropical
cyclones, tsunamis) should be considered in a project
design so as to mitigate likely impacts. At the very least,
such threats should be included explicitly among the
assumptions made when setting project objectives.
In addition, it is critical that a cycle of monitoring and
adaptive management8 is incorporated into all projects to
help to reduce the risk of failure. That is, most of the aims of
a project should treat the project management cycle as a
process that occurs over an ecologically meaningful time
scale (e.g. 10 or more years) and not as a short term
transplantation event (though there are some exceptions to
that rule).
Within the project management cycle there needs to be an
effective monitoring and maintenance regime to reduce risks
such as competition from algae and predation. Appropriately
scheduled maintenance and monitoring throughout the
project life can provide early warning of problems and
trigger adaptive management responses when necessary.
Macroalgae infested Acropora (left) and Pocillopora verrucosa (right) in the Funafuti lagoon (Tuvalu) close to the main township. Indicators like these suggest
eutrophication due to nutrient input from the township and/or a lack of herbivores possibly as a result of overfishing (D. Fisk). A survey of other parts of this lagoon
indicated that the high macroalgal cover in competition with live coral was restricted to parts of the lagoon adjacent to human habitation, suggesting localised
anthropogenic influences on the lagoon ecology. Such information is important in addressing community concerns over the health of their reef. It also suggests that
restoration efforts should be focused on the causes of these impacts (passive restoration) rather than undertaking active restoration in these areas.
31
Risk management is a structured approach to manage uncertainty related to (i) potential threats and disturbances to rehabilitation projects and (ii) the lack of scientific knowledge about reef restoration.
The potential impact of uncertainty can be mitigated by embedding both monitoring and adaptive management in the project design.
Managing risk involves using past experience from other studies, applying those lessons to your project, and being aware that the unexpected is always possible.
Potential risks and uncertainties should be explicitly communicated to stakeholders and funders at the planning stage.
Each project will have a unique set of environmental and socio-economic conditions, such that known risks will vary in their potential impact on the outcome of a project.
At the very least, you can use the lessons learnt from past projects in a structured way to assess the likelihood of the occurrence of known risks, as well as their expected importance to your project.
Clearly defining the aims of your restoration project and understanding the temporal and spatial implications of those aims is a critical initial step in managing the potential risks to your project.
A proper monitoring plan is central to both adaptive management and risk mitigation in a rehabilitation project (not an optional extra).
A key lesson from past active restoration projects is that you should expect the unexpected.
Message Board
What is the role of risk management in reef rehabilitation?
Risk management is predominantly the practice of
systematically selecting cost-effective approaches for
minimising the effect of environmental disturbances and
threats (e.g. predation) to a restoration effort. Be aware that
all risks can never be fully avoided or mitigated (Figure 3.1).
As a consequence, all projects will have to accept some
level of risk.
The risk of disturbance or threat refers to a combination of
the probability or frequency of occurrence of a disturbance
and the magnitude of its consequences.
To further complicate the risk assessment process, you
need to be aware of, and perhaps take into consideration in
your assessment of risk, factors that may not be
immediately apparent with respect to a specific disturbance.
These risk factors can be reasonably predicted to occur as
a consequence of the initial disturbance, but may only
become an issue some time later. For example, following a
Crown-of-thorns starfish (Acanthaster planci) outbreak, a
few large individuals often remain in the area but may not be
in the impacted site where you want to apply restoration
efforts. After introducing new colonies to the denuded site,
the starfish can be attracted to this new source of food and
seriously affect your transplants.

Hawaii (K. Kilfoyle). Interestingly, at a site near Bolinao in the Philippines more
transplanted corals were lost to Crown-of-thorns (COT) predation during a
warming event in 2007 than to bleaching. The site had never had a COT
outbreak in living memory, emphasising that you should always expect the
unexpected when attempting reef rehabilitation.

GOODPRACTICE
Allow for a large margin of error in assessment of the risks
The level of risk assigned to a particular factor should be quite broad toallow for the inherent uncertainties of the risk assessment process. Oneway to deal with the large margin of error is to replicate the restorationefforts over a series of sub-plots within a site and to spread the rehabilitation activities among a number of suitable sites. Varying the mixof coral species and transplant methods used between sites is anotherway of allowing for uncertainty.

3.3 Assessing the most relevant risks during projectdesign
A risk management strategy should incorporate four
essential hierarchical components (Figure 3.2).
1. Definition of aims and objectives
Carefully define the aims and objectives of your rehabilitation
project (if a location is already assigned). Alternatively, if the
aims are already assigned, then carefully choose the
location so that they may be achievable. The original aims
of a restoration project will determine the range of risks that
you need to take into account. Many of those potential risks
can affect a number of different project aims. In general,
restoration primarily endeavours to improve ecosystem
structure and function in degraded reef areas. Your project
objectives may range from passive indirect measures, to
active direct measures, all with the purpose of redressing
certain defined aspects of reef degradation or damage.
2. Selection of natural and social setting
Once a location and project aims are established you need
to consider carefully the natural and social setting of the
proposed rehabilitation site. This will refine the range of risks
that you need to consider in a rehabilitation plan. In most
instances, you will need risk predictions relating to the
ecology of the site, and to the natural and anthropogenic
threats, which will be unique for a particular site.
Management of risks will depend also on the social context
of the restoration site and your project aims. “Social
context” refers to the human influences and decision-
making structures in place at the location, specifically, the
degree to which the key stakeholders are involved, and are
in agreement on, the restoration aims and activities.
3. Assessment of possible risks
A full risk assessment needs to be an integral part of the
project design phase and should be carried out early on so
that the outcomes can be built into the implementation
phase (Chapter 2). Scoping and field assessment by a
specialist is strongly recommended during the design
phase. Risk factors should be collated and assessed at the
initial scoping stage by the team undertaking the project (a
team that ideally includes a reef ecologist, project
managers, decision-makers, and local community
members). Critical environmental and biological factors that
may impact your project need to be assessed via the input
of an experienced reef ecologist who is able to interpret the
environmental signs that are present at the site selected for
rehabilitation. This will include an assessment of previous
environmental and human usage trends of your site.
Assessing and interpreting trends in the past history of a
site should help guide the planning of the rehabilitation
project and allow you to make it more robust to
disturbances.
4. Screening and prioritisation of risks
The management of risk requires that you compile as much
information as possible on biological, environmental, and
social risk factors that relate to your site and prioritise these
to arrive at a strategy of where, when, and how to proceed
(which can also include the decision not to proceed). The
iterative nature of the risk management process may mean
that factors originally classed as low risk could become high
risk factors during the project’s life. We strongly recommend
that the risk management plan includes provision for regular
reviews of progress and conditions at the site. This allows
the project to change emphasis and methodology if
necessary in order to achieve its aims, i.e. your project
design needs to be flexible and reactive to changing
threats8.
Ideally, you should follow a prioritisation process whereby
the risks with the greatest loss and the greatest probability
of occurring are addressed first, and risks with lower
probability of occurrence and lower resultant loss are dealt
with in descending order. In practice, the process of
prioritisation can be very difficult to complete, and balancing
between risks with (1) a high probability of occurrence but
lower loss, and (2) a high loss but lower probability of
occurrence, can be difficult.
3.4. Five-step process for prioritising and managingrisks
To manage risk, a structured response related to perceived
threats can minimise the chance of failure of a restoration
project. The response strategies include:
• avoiding the risk,
• mitigation strategies for reducing the negative effect of
the risk, or reducing the magnitude of loss, or probability
of occurrence,
• spreading the risk among other components of the
project (by replication of effort in different spatial, species
composition, and temporal settings, e.g., by spreading
A lone Acropora coral colony on a macroalgae dominated reef (N. Graham).
Unless the broader management issues which have allowed the seaweed to
dominate are resolved first, there is high risk that active restoration measures
will fail.

the risk among different habitats, or between different
species groups or source areas, or over different times
of the year or different environmental conditions), and
• accepting some or all of the consequences of a
particular risk and budgeting for that factor.
An initial planning and assessment exercise where you
predict the risks to the project and plan how you will
manage these risks, should be based on local, regional,
and global knowledge, and should include the following five
steps.
1. Setting out your rehabilitation project’s specific aim(s).
Once you have established and agreed your aim(s) with all
stakeholders, then specific spatial and temporal
requirements for the project will result from the aim(s). The
assessment of risk involves a proper understanding of the
spatial and temporal scale implications of each aim.
2. Defining the risks associated with the natural (biophysical)
and social setting of the proposed rehabilitation site.
3. Assessing and prioritising the risks to your project early
on during the design phase (listing, assigning a perceived
probability of occurrence and magnitude of impact
(i.e. consequences) to each risk, and then prioritising).
4. Development of response options for mitigation of risks
using realistically available technological, human and
organisational resources.
5. Integration of earlier steps to develop a Risk Management
Plan.
Step 1. Setting out your project’s aim(s), and understanding the spatial and temporal implicationsof those aims
The conditions under which your project will operate are
partly determined by your aims and objectives, and partly by
the social and ecological circumstances of the
site chosen for restoration. Often a project will have several
aims and objectives but for simplicity, each major aim will be
treated separately here. You will need to assess and
prioritise any conflicting risk factors when more than one
main aim is identified for a single project.
Risk management considerations relating to the most
common aims (see Box 3.1) are outlined below.
Box 3.1 Rationales and aims of reef rehabilitation.
Common reasons for carrying out reef restoration interventions include:
• Lack of awareness in a local community and a poor appreciation of the economic and cultural value of
reef ecosystems.
• Loss of biodiversity.
• Loss of productivity (food species).
• Loss of key reef components (usually coral, but also adjacent seagrass or mangroves) due to natural
disturbances (bleaching, storm damage, coral predation and disease),
• Loss of key ecosystem processes (e.g. recruitment of juvenile corals, grazing of macroalgae by
herbivorous fish or urchins) and services.
• Provision of alternative livelihoods (e.g. culture of aquarium products, tourism) for stakeholders who
agree to stop harvesting reef resources.
• Mitigation for developments that will adversely impact coral reef species at a site, especially the
relocation of threatened corals.
Common aims that previous restoration projects have cited as their motivation include:
1. Building public awareness and environmental education.
2. Promoting recovery of biodiversity.
3. Increasing biomass and productivity.
4. Assisting recovery of key reef species or ecosystem processes.
5. Development of alternative livelihoods.
6. Mitigation of damage or degradation.

35
1. Building public awareness and environmental education
Often the aims of raising awareness of coral reefs and
education of local communities result in demonstration
projects that have to be located at readily accessible sites
situated in areas where communities can claim ownership of
the activity and/or where some degree of surveillance of the
site can be done by that community. The objective is to
have high community visibility and awareness of the project.
Risk management messages
• There is a risk that practical considerations may take
precedence over ecological considerations, leading to
poor restoration outcomes due to low attention to
ecological requirements.
• Although stimulating community involvement in a project
is very important, you need to be careful that this aim
does not jeopardize other aims, that is, multiple aims
can be hard to manage effectively as the pursuit of one
aim can negatively influence the success of another
(e.g. Ch 8: Case study 2).
• Awareness/education projects are usually small in
spatial scale and do not generally last for more than a
couple of seasons or years. While building awareness,
they therefore tend to have poor outcomes in terms of
real reef rehabilitation. As a consequence, we would
advise that this aim should generally be adopted without
linking other (e.g. ecological) aims with it. There is, of
course, a danger that poor ecological outcomes will be
counterproductive in terms of public engagement, so
the consequences of ecological compromises driven by
“public awareness” convenience need to be considered
very carefully.
• On the other hand, large long-term rehabilitation
projects not necessarily constrained by the practical
requirements of education and awareness building, can
deliver education and awareness benefits at
appropriately accessible sites (e.g. Ch. 8: Case study 9).
2. Promoting recovery of biodiversity
A biodiversity protection aim using active restoration,
requires that your project design will result in a functional
and diverse reef community. Often, an implied outcome is
that reef resilience will be enhanced through fisheries
management9 or through the preservation of a specific coral
species. Conversely, passive restoration to control fishing
and build herbivore populations can markedly increase
resilience.
Risk management messages
• Sites that are most ecologically suitable for enhancing
and promoting biodiversity may be difficult to work and
can entail high logistical costs.
• Biodiversity preservation is a long-term aim that requires
long-term management and maintenance to be
successful.
• Active restoration efforts cannot automatically build a
resilient community though in theory, they can enhance
resilience through the establishment of a diverse range
of healthy mature colonies. It may take decades before
a highly diverse and resilient community can be
established.

Acropora florida colony (D. Fisk). Careful examination of feeding scars and adjacent areas is necessary to distinguish between Drupella, disease, fish bites, Crown-of-
thorns starfish and other causes of lesions. Note the rapid reduction in live coral tissue (evidenced by the fresh white scar area with no sign of colonisation by turf
algae). High incidences of coral predators are a significant risk to restoration efforts and can be difficult to manage, generally requiring constant vigilance and
maintenance efforts.
36
3. Increasing biomass and productivity
A productivity aim usually relates to a focus on fisheries
enhancement by restoring or creating suitable reef habitat for
commercial or subsistence fishery species (both
vertebrate and invertebrate). Some previous projects have
focused on increasing habitat complexity and providing
refuges for fishery species by active restoration (e.g. Ch. 8:
Case study 2) whereas enforcement of no-take areas
(passive restoration) can also generate significant rises in
fish biomass without habitat modification (e.g. Ch. 8: Case
study 10).
Risk management messages
• In general, meaningful gains in biomass or productivity
are rarely achieved by active restoration techniques
because of their small spatial scale. Such techniques
cannot be applied at a suitably large spatial scale, i.e. at
scales orders of magnitude larger than the current
practical limit of restoration techniques (1–10 ha).
• You will need to incorporate a medium to long-term
project timeline (3+ years, depending on the species
involved) to achieve any tangible measure of success,
as multiple recruitment seasons are usually necessary to
allow for build up of fishery biomass. The implications
are that effective management input over the long term
will be required also.
• In contrast, passive restoration techniques (effectively
managing the drivers of reef degradation) can be
reasonably expected to result in productivity gains given
sufficient time. However, depending on the main sources
of degradation that were present, any productivity gain
may be highly variable among potential sites10.
4. Assisting recovery of key reef species or ecosystemprocesses
This aim is usually achieved by passive restoration efforts
that are expected to result in increased natural recruitment or
survival rates of corals, fish or other reef species. The
assumption is that natural build up of key reef species will
occur under favourable environmental conditions (e.g. the
absence of disturbance factors), and in time will result in
higher recruitment and survival rates, and eventually a more
biodiverse and resilient reef system. It may be assisted by
active restoration (e.g. transplantation of Acropora palmata in
Case studies 6 and 9 in Chapter 8).
Risk management messages
• Restoration of key reef species may initially be at a small
spatial scale (e.g. by focusing on managing key habitat
for selected species) with the expectation that those
small areas will then enhance recruitment elsewhere in a
reef system. This is difficult to achieve. For example, key
habitat may be fish spawning aggregation sites or
naturally high coral diversity areas that are expected to
supply recruits to other areas. The rationale for this
approach assumes there will be adequate connectivity
and larval dispersal, that larval survival will be adequate,
and that other natural processes will be favourable to
recovery.
• The project design and resourcing need to reflect the
likely timescale of recovery; this may vary from 5 years
to decades depending on the severity and spatial scale
of the impacts.
5. Development of alternative livelihoods
This aim usually entails an agreement with local
communities or resource owners for restricted harvest
regimes in exchange for income from (i) fees to resource
owners, (ii) employment in tourism (e.g. as guides, boatmen),
(iii) aquaculture, or (iv) coral farming to provide products for
the marine aquarium trade or support re-establishment of
selected species into natural populations or tourism related
habitat enhancement. The aquaculture of highly prized giant
clams (Tridacna spp.) for food or as an aquarium species is
an example.
Restoration techniques can also be employed to accelerate
recovery at or enhance sites that are already tourist
attractions, are being developed for tourism or have been
damaged during resort construction (Ch. 8: Case study 3).
Examples are sites that are used as underwater snorkel trails,
and boat underwater viewing areas that may have been
damaged by storms, predation, disease or bleaching events.
Sites that are adjacent to a tourist resort also can provide
added economic value to the resort if attractive reef habitat
is made readily accessible to guests.
Risk management messages
• You may need to consider establishing aquaculture
activities at sites, which although ecologically suitable for
the chosen species, may be logistically challenging.
• The growth rates of species (corals, clams, urchins,
etc.) being cultured for the aquarium trade or for
re-establishing depleted natural populations, will
determine the minimum time scale needed. You need to
ensure that the time-scale of budgetary support
matches the aquaculture cycle.
• If proposed aquaculture involves use of feeds for fish,
then beware of potential eutrophic impacts.
• When multiple aims are adopted, conflicting species
requirements may occur. For example, the demands of
aquarists (who require small colonies of very specific
species, colours, etc.) will be different to those of
managers aiming to enhance natural populations. Thus,
two complementary sets of nurseries, one for income
generation, one for rehabilitation might be needed.
These issues need to be explored at the project design
stage.
3
8
• Enhancing or accelerating recovery at a site with high
tourism value means that the choice of site is
predetermined (rather than being selected as part of the
project design phase) with the risk that the site may not
be optimal in terms of likely restoration success. Critical
parameters to consider include: allowing sufficient time
for attachment and growth of transplanted corals (1–2
years), and planning for longer periods (3–5 years)
before gradual natural accumulation of fish and other
organisms from natural recruitment processes are
noticeable in the restored area (in contrast to short-term
build up of fish abundance via the attraction of fish
already in the vicinity, e.g. through the introduction of
artificial reef structures).
6. Mitigation of damage or degradation
As stated in Chapter 1, mitigation of damage refers to
the reduction or control of the adverse environmental
effects of a project, but it also includes restitution for any
damage to the environment through replacement,
restoration, or creation of habitat in one area to
compensate for loss in another. This often involves
moving corals and other organisms from a designated
high disturbance site (usually due to a development) to
an adjacent site outside the development impact zone.
Relatively short time scales (2+ years) are probably
required to assess the survival (success/failure) of the
transplantation. Success will depend on how well the
transplants adapt to the new site, and where necessary,
whether there has been adequate attachment.
Risk management messages
• When re-locating corals and other organisms you
should try to re-create the spatial arrangement (paying
particular attention to zonation and depth) and density of
organisms that existed at the source site and ensure
that the receiving environment is compatible (e.g. with
respect to current/wave exposure) with the original one.
To do this you need to find a relatively bare or previously
degraded site that has biophysical conditions as similar
as possible to the original source site. However, finding
suitable sites for relocating corals can be difficult as
logically, coral communities would be expected to
already exist at similar non-impacted sites. Thus, by
implication, relatively bare areas may well be unsuitable
for reasons that are not clear (e.g. susceptibility to
decadal or longer-term disturbances).
Step 2. Defining risks associated with the naturaland social setting of the rehabilitation project
To define the risks associated with the natural setting you
need a full description and analysis of the rehabilitation site,
including key factors that influence the physical and
biological processes that shape the reefscape. The major
sources of natural or environmental risk and the main risk
factors associated with each, along with predictive threats
and management responses, are outlined in Table 3.1.
Those related to the natural setting include:
1. History of natural and anthropogenic disturbances at a
site,
2. Connectivity and spatial relationships of a site with
respect to the hydrodynamic regime (tidal characteristics,
marine and coastal ecosystem links, terrestrial links, regional
marine connectivity), and
3. Coral transplantation issues (sources of coral transplants
and potential collateral damage, transplant species and
growth forms, life history and reproduction).
To define the risks associated with the social setting you
need to identify all human related factors concerned with
governance, decision making, and ownership issues
affecting the site. The major sources of social or human
associated impacts and the main risk factors associated
with each, along with predicted threats and possible
management responses, are outlined in Table 3.1. These
can be split into:
4. Social and political setting – local social and political
factors (site selection implications, local decision making
and management arrangements, stakeholder
understanding, unpredictable factors, effects of local
economic changes, protection, post-funding stakeholder
issues), and
5. Management issues – administrative considerations
(adaptive measures, training and capacity of personnel,
stakeholder engagement, monitoring and reporting
protocols).

Step 3. Assessing and prioritising the risks to yourproject
Once you have identified the main risks, you then need to
assess them as to their potential severity and probability of
occurrence. In some case these can be fairly easy to
assess but in others they may be more or less impossible
(e.g. in the case of the probability of a rare event occurring).
Therefore, in the assessment process you may need to
make educated guesses in order to prioritise the risks and
develop a risk management plan. The person who is
assigned to do this assessment will be critical to the whole
design and risk management process. The pragmatic
adoption of realistic aims will be equally important for the
potential success of a project.
The fundamental difficulty in risk assessment is determining
the probability of occurrence of a particular risk since
Good Practice Checklist
Use an experienced coral reef ecologist to provide input at the design stage of a projectand ensure that one is available for advice in the event of problems during subsequentstages, so that the predominantly biological risks to the success of your project can beaddressed in a timely and appropriate manner.
Make full use of the huge amount of useful information that is available free over theinternet (see web links in reference sections of each chapter).
Choose your rehabilitation site with great care and with full consideration of the ecological and logistic implications.
Ensure that there is adequate management control of the rehabilitation site so thatadverse human impacts (e.g. destructive fishing practices) will not jeopardise your project.
Carefully research the optimum time of year for transplantation at your site and seek toavoid particularly stormy or warm times of year.
To spread risk, replicate transplant sites whenever feasible, creating several well-separated patches of coral rather than a single large patch.
Make sure you only transplant coral species or growth forms that are well-adapted tothe conditions at your proposed rehabilitation site, using a “reference site” as a guide towhat these are if need be.
Within the constraints of the previous item, seek to use as wide a cross-section of common coral species and genotypes as you can, to increase the chance that somecolonies will be resistant to any disturbances that may occur.
Foster local support for your project by engaging fully with stakeholders, the communityand local government units and use monitoring results to increase public awareness,report progress and maintain the project’s media profile.
Prepare for the unexpected by building into the project plan the capacity for monitoringand adaptive management in response to changing needs or setbacks.
statistical information is not available on past incidents that
led to failure or significantly reduced successful outcomes.
Furthermore, evaluating the severity of the consequences
(impact) is often quite difficult also. You can attempt to
quantify the risks by using the following approach: Likelihood
of occurrence coupled with the predicted consequences
(impact of the event) defines the severity of the risk, where a
rank value can be assigned to each of the risk categories
(Table 3.2). In the table, the predicted consequences of a
risk are cross referenced to the predicted likelihood of
occurrence to produce a potential risk ranking (ranging from
1 = near zero risk to 4 = high risk).
Where a number of specific risks are identified as likely to
impinge on your project, a sum total of the risk rankings
provides some guidance as to whether the project has a
reasonable chance of success. The higher the sum of the
46
risks, the higher the potential for failure or compromised
project outcomes. The presence of several high risk factors
would be particularly worrying. This exercise can be utilised
in an iterative way, by altering the risk rankings according to
the inclusion of additional provisions in the design phase
that will mitigate certain identified risks (in the process,
reducing the rank value of that risk), thereby improving the
overall success potential of your project.
The final risk assessment matrix should be critically
assessed as to whether it truly incorporates all of the most
likely known and predicted risks. If there are several aims,
then risks to one from a given factor may be greater than to
another, in which case the more severe risk category should
be chosen.
Table 3.2 A method to rank the severity of risks by
incorporating the estimated likelihood of risk occurrence and
predicted consequences of risk impact. H = High Risk
(Rank value = 4), M = Medium Risk (Rank value = 3),
L = Low Risk (Rank value = 2), NZ = Near Zero Risk (Rank
value = 1).
Step 4. Development of response options for mitigation of risks
Depending on the ranking of the most relevant and likely
risks associated with a restoration project under each of the
major aims, a list of appropriate responses can be
developed. Suggested responses are outlined in Table 3.1.
Note that specific risks can occur at various spatial and
temporal scales so you most likely will have to address
several risk factors in a given project. You may also need to
develop site-specific responses that are not covered on this
list.
The aim of mitigation is to ensure that perceived risks are
minimised. If risks are in the medium or high category, a
reassessment of how to minimise those risks may mean
changing the initial project aims and design. Also, many
risks might be associated with a selected site, so to
minimise the risks, you may be required to look for an
alternative site or to even abandon the project if viable
alternatives are not available.
Table 3.1 is presented as a series of risk sources, the
information you need to obtain in order to evaluate them,
the specific risks associated with each source, and the
appropriate management response to mitigate or minimise
the threat from these risks. Many of the responses just
involve careful planning and prior thought.
Likelihood of risk Consequences of risk impact occurrence
Severe Moderate Mild Negligible
High H H M/L NZ
Medium H M L NZ
Low M M/L L NZ
Negligible L L L NZ
Step 5. Integration of earlier steps and developmentof a Risk Management Plan
At this stage, you may need to enter into an iterative
process and reconsider your original aims or the suitability
of your selected site in order to reduce the level of risk from
the most significant of perceived threats.
Due to the uncertainties in our scientific knowledge, a key
part of the Risk Management Plan may be to use monitoring
to provide more information as the project proceeds and
use this to guide adaptive management to correct problems
arising, as well as to provide feedback to stakeholders.
Thus monitoring is central to adaptive management and risk
mitigation and not an optional extra. The key is flexibility and
the capacity to respond to changing circumstances as
indicated by the arrows in both directions between stages 4
and 5 in Figure 2.1 and those between these stages and
the financial and human resources available.
Ultimately, all you can do is try to mitigate for likely risks and
be in a position to respond to less likely ones. With careful
project design and systematic consideration of the risk
factors in Table 3.1 and their mitigation, you can reduce the
chances of your rehabilitation project failing but you can
never guarantee success.

A local diver in Tuvalu inspects a coral transplant for unwanted predators and
macroalgae on the skeleton prior to transporting it to a rehabilitation site
(Ch. 8: Case study 2). The coral had feeding or disease scars which
signalled that particular care was needed to ensure that no predators or
disease were transferred to the rehabilitation patch. Alternatively, this colony
may have had to be rejected (D. Fisk).
