Up to 335,000 hedgehogs are dying each year on UK roads, a study suggests.
The figure represents a three-fold mortality rate on 2016 data, described as "alarming" by a team at Nottingham Trent University (NTU) researchers.
A study in 2016 put the UK road death figure at 100,000 but experts suggested that was a "mid-line estimate".
Researchers said measures such as tunnels and speed bumps "could" protect the animals but ultimately relied on drivers' behaviour to change.
PhD student Lauren Moore led the review, which has been jointly funded by wildlife charity People's Trust for Endangered Species (PTES) and NTU.
