Biodiversity Indicators in Your Pocket - BIYP

Updated 2009


Uk Biodiversity Indicators in Your Pocket 2009Biodiversity is the variety of life on earth. It includes the diversity of individual species, the genetic diversity within species and the range of ecosystems that support them. The UK Government has committed to two important international targets to protect biodiversity:


  1. In 2001, European Union Heads of State or Government agreed that biodiversity decline should be halted with the aim of reaching this objective by 2010
  2. In 2002, Heads of State at the United Nations World Summit on Sustainable Development committed themselves to achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional and national level, as a contribution to poverty alleviation and to the benefit of all life on Earth

A suite of biodiversity indicators for the UK was first published in June 2007. The indicators show changes in aspects of biodiversity such as the population size of important species or the area of land managed for wildlife. They provide part of the evidence to assess whether the targets set out above have been achieved.


Eighteen UK biodiversity indicators are presented, although one, habitat connectivity, is still under development and presented with limited data. The indicators are grouped under the six focal areas aligned to those used by the Convention on Biological Diversity and in the European biodiversity indicators:


  1. Status and trends in components of biodiversity
  2. Sustainable use
  3. Threats to biodiversity
  4. Ecosystem integrity and ecosystem goods and services
  5. Status of resource transfers and use
  6. Public awareness and participation

Whilst indicators are useful tools for summarising broad trends and highlighting high-level messages, they can never describe all the changes in the UK’s biodiversity. They are best seen, as their name suggests, as indicative of the general state of biodiversity.  Whilst they will form the basis of the UK’s assessment of progress towards the biodiversity targets, other factors and sources of information are also being taken into account.
