BIODIVERSITY AND THE DEVELOPMENT OF THE KENT PLAN Biodiversity is simply "the Variety of Life". It encompasses the whole range of animals, plants and micro organisms on earth, from the tiniest bug to the mightiest oak, along with the ecosystems in which they live. 1.1 CONSERVING BIODIVERSITY This was the start of the UK Government's commitment to biodiversity and since then there have Conserving biodiversity is not just about rare and been a number of key stages in taking forward threatened species and habitats, but the common-place biodiversity issues in the UK: as well.
