Recreation is an important use of many coral reef areas. Recreational uses can be extractive (e.g., fishing) or non-extractive (e.g., diving, snorkeling, boating, and catch-and-release fishing). Such uses are a source of pressure on coral reefs and a source of income for the community. Recreational users and commercial tourism operators play an important role in reef conservation and management and are often key partners with reef management agencies in efforts to protect coral reefs.

Through a balanced approach focusing on sustainable use, recreational uses can be managed to minimize their impacts on coral reefs while strengthening the contributions of recreational users to reef management and the economy. Key approaches for managing recreation include setting limits, managing reef activities, and encouraging best practices.

Setting Limits

• Carrying capacity — One approach to preventing unacceptable impacts from human use is to set limits on numbers of users and types of activity based on the capacity of the ecosystem to cope with impacts. In practice, it can be difficult to determine environmental carrying capacity, but limits can be set using best available knowledge and an approach inclusive of reef users.
• Limits of acceptable change (LAC) — This involves setting limits based on reef users’ behavior and can be a powerful approach for getting users (especially commercial tourism operators) to adopt best practices, as the numbers of users is dependent on the size of their ecological footprint. A key requirement of an LAC approach is a system for regularly monitoring reef condition as part of a dynamic management system with thresholds and actions.

Managing Reef Activities

Once the amount of sustainable use at a site has been established, managers need to implement systems for managing activities. Where recreational use is managed through regulation and/or a permit system, enforcement can occur through a combination of self-regulation, spot-checks, and surveillance. Non-commercial uses often do not require permission, so less regulatory approaches may be needed to reduce impacts such as anchoring, crowding, and excessive vessel traffic.

Installation of mooring buoys and associated education campaigns can reduce the amount of anchoring. Reduced shore-based infrastructure, such as limited vessel berths or car parking at boat launch sites, can help control the amount of boat traffic around a reef. User-pays systems, such as day passes, can be used to cap numbers of visitors to a site or disperse use to a wider area and reduce pressure on the most popular sites.

A range of other approaches can also be used to reduce concentration of use to a fewer number of hardened sites, such as installing moorings or installing attractions (for example, artificial reefs or underwater sculpture parks, such as those in Mexico).

Encouraging Best Practices

The impacts of recreational activities can also be reduced through environmentally sensitive behavior. There are many sources of information on best practices for tourism that help to codify behaviors that reduce risks to reefs. These include the Responsible Reef Practices developed for the Great Barrier Reef and guidance provided by the Coral Reef Alliance and the Green Fins program.

Even for extractive recreational activities like fishing, impacts can be reduced through setting and enforcing bag and size limits, and by encouraging adoption of best practices. Adoption of best practices can be encouraged through systems of formal recognition such as eco-certification programs and eco-rating schemes.
