Regional Chapters support the mission and the global efforts of EERN and aim to stimulate the involvement of a variety of people, institutions, organisations, and companies. They play a crucial role within EERN as they have the ability to work with individuals and institutional partners more directly and establish a networking system in the locale.

EERN starts by establishing ten chapters internationally. These chapters will organise regular meetings and social events. In addition, they will be involved in workshops, educational programs, seminars and other events to promote the ecosystem approach, foster research and collaboration, and support networking.
