This strategy featured in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommended promoting improved international coordination of measures for effective conservation and management of endangered/non-pest migratory species, including appropriate levels of support for establishment and management of protected areas in transboundary locations.
The Convention on the Conservation of European Wildlife and Natural Habitats, known as the Bern Convention, aims to conserve wild flora and fauna and their natural habitats, especially those species and habitats whose conservation requires the co-operation of several States, and to promote such co-operation. Particular emphasis is given to endangered and vulnerable species, including endangered species. There are special provisions for migratory species to hunting and schedules of protected species and prohibited means and methods of killing, capture and other forms of exploitation. The Bern Convention Secretariat is located within the Council of Europe.
