The Flyway Site Network not only identifies and includes sites of international importance for migratory waterbirds to promote improved protection and management, but also aims to link those sites through sharing information and capacity building.

The EAAFP Sister Site Program brings together Flyway Network sites in different countries that share species to encourage increased awareness of their shared migratory waterbirds and link sites through collaborative activities to promote the conservation of these birds. It is designed to offer a better chance to be engaged with other sites in the Flyway Site Network to conduct collaborative research and monitoring on shared species and exchange information and experience, which is critical for site managers and decision makers to reinforce conservation action. Capacity building is an important element of sister site relationships and exchange visits can help site managers learn new and innovative approaches to different aspects of site management, from visitor centre development to participatory wetland management techniques.

As on May, 2023, there are 12 Sister Site Agreements, from 21 sites across 7 countries. The EAAFP encourages further cooperation between existing or potential Network sites. The present list may not include all the arrangements and diverse activities in place along the Flyway. Please contact the EAAFP Secretariat if you would like to provide further information.

EAAFP Sister Site Program Guidelines

The 11th Meeting of Partners (MOP11), which was held in March 2023, adopted guidelines for the EAAFP Sister Site Program. The guidelines contain a basic understanding and steps to establish the Sister Site Program, including several case studies and how to exchange knowledge effectively.
