The Bern Convention is a binding international legal instrument in the field of nature conservation, which covers the whole of the natural heritage of the European continent and extends to some States of Africa. Its aims are to conserve wild flora and fauna and their natural habitats and to promote European co-operation in that field. The UK is a signatory to the Convention which was established at Bern, Switzerland in 1979.
The UK Biodiversity Action Plan (UKBAP) was published in January 1994 in response to Article 6 of the Biodiversity Convention, to which the UK became a signatory in 1992. The Convention was established in Rio de Janeiro in that year. The Biodiversity Convention requires national governments to develop national strategies for the conservation of biological diversity and the sustainable use of biological resources.The UKBAP was replaced by the UK post-2010 Biodiversity Framework which is the UK government’s response to the new strategic plan of the United Nations Convention on Biological Diversity published in 2010. It focuses on how to deliver the outcomes set out in the government’s Biodiversity 2020 strategy. In the United Kingdom, many local partnerships have also produced local biodiversity action plans (LBAP).
