Nature in the United Kingdom is in decline. Populations of priority species have decreased by more than 60% since the 1970s, and there is no evidence of a reversal in this trend. UK landscapes are under more pressure than ever to deliver housing, infrastructure and food. Several species, including once common animals such as the European hedgehog, are in danger of disappearing forever. We need to ensure that policy and conservation methods protect the best of the biodiversity that we have left within the UK.
