Your local endangered species guide looks at twelve endangered species across different regions of the UK.

As humanity thrives, nature suffers – at least this has, sadly, been the case in the UK for much of the last century. Many species are in decline as a results of irresponsible environmental practices and building, reducing their natural habitats. From bats in the South West to the Scottish Wildcat, they’re all here.

Quick Numbers:

59,000 – Estimated number of species native to the UK.

747 – Number of species under threat of extinction.

60% – Percentage of 3,148 surveyed species that have declined over the last 50 years.

31% – Percentage of 3,148 surveyed species that have strongly declined over the last 50 years.

1,150 – Number of species listed as a priority concern.

We’ve had some amazing and detailed responses from the mentioned charities that support the concerns shown and, in some cases, suggest that the numbers are even lower than our research suggested. Take a look below the infographic for those responses.

Hedgehog threats and decline

Henry Johnson, a spokesperson from the People’s Trust for Endangered Species (PTES), got back to us and wanted to further interrogate the population and decline of British hedgehogs. As shown in his Wikipedia entry on hedgehog population, ‘the widely-quoted estimate of 30 million was based on an estimate of 36.5 million by Burton’ (see Wiki), however his estimates are now considered inaccurate. ‘The most current estimates are that we’ve lost a third of the national population in the last decade.

Johnson disputes the population numbers, saying ‘[1,100,000] is the last published scientifically respectable estimate for hedgehog population size, but in light of their decline since then, PTES state that we think there are fewer than a million animals left in the UK. It us hard to be exact as there is no way of accurately measuring hedgehog population size, but if we’ve lost a third of the population since 2000, there can’t be 1,100,000 any more.’

If you are still interested in helping, PTES and the British Hedgehog Preservation Society (BHPS) have a joint campaign, Hedgehog Street.
