The United Kingdom Biodiversity Action Plan or (UK BAP) was the UK government's response to the Convention on Biological Diversity, opened for signature at the Rio Earth Summit in 1992. The UK was the first country to produce a national Biodiversity Action Plan. It was published in 1994 and created action plans for priority species and habitats in the UK that were most under threat so as to support their recovery.
The UK Biodiversity Action Plan summarised the most threatened or rapidly declining biological resources of the United Kingdom, and gave detailed plans for their conservation. Individual 'Action Plans' were provided for these habitats and species, and a reporting mechanism was established to demonstrate how the UK BAP was contributing to the United Kingdom's commitment to help reduce or halt the significant losses in global biodiversity, highlighted by the international Convention on Biological Diversity. The original publication included action plans for 45 habitats and 391 species, each identified either as being globally threatened, or where evidence showed there had been a particularly rapid decline of those resources within the UK. Although mainly focused on England, Wales, Scotland, Northern Ireland and the UK Crown dependencies, the UK Biodiversity Action Plan also addressed issues of declining species and habitats overseas in the UK Dependant Territories and British-held territories in Antarctica; areas together containing over 700 endemic species.
At the launch of Biodiversity: The UK Action Plan in January 1994, the UK Prime Minister announced the formation of a 'Biodiversity Steering Group', drawing on experts from key conservation organisations and government agencies. It was tasked with identifying and preparing costed action plans for priority species and habitats by 1995, and with developing methodologies for monitoring progress and improving public awareness and access to biodiversity information. In 1995 the Biodiversity Steering Group published a two-volume report, the second part of which contained three important lists of species:
The criteria for selection as a Biodiversity Action Plan species on the 'long list' were:
After devolution in 1998, England, Wales and Scotland had all developed their own individual biodiversity strategies by 2002, with Northern Ireland following shortly afterwards, whilst still also collaborating together.
