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.

Crown-of-thorns starfish (Acanthaster planci) eating a Pocillopora colony in

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.

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).
