Coral Reef Restoration Guidelines

Ewout Knoester

Restoration activities are becoming more and more popular across the world, in an attempt to restore/sustain the function and services associated with coral reef ecosystems. It should be noted that these efforts are unlikely to be effective as a stand-alone action, they should always be done as part of a larger integrated management strategy.

Below we have compiled some of the most recent guidelines on coral reef restoration. Should you know of any additional guidelines that are relevant please send them to Claire Rumsey.

UNEP will release a report on coral reef restoration in early 2021

In anticipation of the coming UN Decade on Ecosystem Restoration, and as a response to the UNEP Assembly resolution 4/13 adopted in 2019, The United Nations Environment Programme assembled a team of experts to produce a report on coral reef restoration as a strategy to improve ecosystem services. The report presents an overview of current methods and the best available knowledge in the field of coral reef restoration. A set of recommendations are also provided to assist key actors such as managers, practitioners, policymakers, and funding agencies to make informed decisions in applying coral reef restoration more broadly as an integrated reef management strategy. The report along with a policy brief and an animated video are expected to be released in January 2021.

Managers Guide for coral restoration (2020)

The Manager’s Guide to Coral Reef Restoration Planning and Design supports the needs of reef managers seeking to begin restoration or assess their current restoration program. Based on global best practices, the Guide was developed for reef managers and practitioners, and anyone who plans, implements, and monitors reef restoration activities. Together with a suite of tools and templates, the Guide maps out a six-step, iterative process to help users gather relevant data, ask critical questions, and have important conversations about restoration in their location, culminating in the creation of a Restoration Action Plan to enhance reef resilience and recovery. Within the guide are two Appendices and other tools that can (and should) be used to assist readers in developing a restoration action plan;

  • Workbook (.doc) – helps document the process, information, and decisions made during Steps 1-4 of the planning cycle.
  • Action Plan Template (.doc) – can be used to shape a Restoration Action Plan using information summarized when completing the Workbook.
  • Step 2 Tutorial and Complete Example (.xlsx) – presents a worked example of how to compile, sort, and analyse data to assist in selecting sites for restoration.
  • Step 3 Intervention Criteria Evaluation Tool (.xlsx) – helps evaluate and then select restoration intervention options.

Coral reef restoration monitoring guide: Methods to evaluate restoration success from local to ecosystem scales (2020)

The Coral reef restoration monitoring guide: Methods to evaluate restoration success from local to ecosystem scales. This guide will help any restoration group or government – large or small – decide on a monitoring regimen that fits their budget and capacity. The guide took more than two years to put together – and we are sure this will be a crucial resource to the community as more and more countries engage in coral restoration.

Training Guide for Coral Reef Restoration (2020)

This Guide is a practical, complementary tool for coral reef restoration training. Any individuals wishing to start a restoration project must contact local authorities to learn about the legal implications and obtain the corresponding permits, as well as join working groups with restoration experience to receive proper training. It was produced the Mesoamerican Reef Fund (MAR Fund), Mesoamerican Reef Rescue Initiative (RRI) with the support of ICRI and the UN Environment Programme Small Grants Program.

A guidebook for coral propagation through asexual reproduction- revised version (2019)

The English translation of the Japanese coral restoration guidelines. These guidelines provide an overview of the characteristics, functions, and current state of corals in Japan, coral propagation plans and how to go about it. In chapter two it details whole-area propagation techniques for corals and the different methods that could be utilised.

Note: all the text was translated by James Cook University from the Japanese publication of “A guidebook for coral propagation through asexual reproduction- revised version” produced by the Fisheries Agency, the Ministry of Agriculture, Forestry and Fisheries of Japan on their web site (https://www.jfa.maff.go.jp/j/seibi/sango_tebiki.html). All the responsibility of the English text is on the James Cook University, but not the Fisheries Agency.

Guidance document for reef management and restoration to improve coastal protection (2018)

This guidance document aims to provide a review and recommendations on reef management and restoration for risk reduction. It synthesizes evidence of the role coral reefs play in coastal protection and the reduction of risks during disasters. It presents ecological, geological, and oceanographic factors that contribute to the coastal protection capacity of reefs and the factors that reduce this capacity. It also presents an array of risk reduction solutions to restore reef protection services, and management approaches that can help support its coastal protection values.
