and hedgehog are vanishing before our eyes.
"Reliable data on these species goes back just 50 years, at most, but we know that there has been a historical pattern of loss in the UK going back even further.
"Threats including sweeping habitat loss, changes to the way we manage our countryside, and the more recent impact of climate change, have had a major impact on our wildlife, and they are not going away."
The study's analysis of populations and range of 3,148 species dating back up to 50 years ago represents just 5% of the UK's estimated terrestrial and freshwater species, with many, particularly insects, plants and fungi, lacking sufficient data for assessment.
Some 6,225 species could be assessed under Red List criteria for their extinction risk and 755, or 12% were found to be under threat.
