Anger in Oxfordshire village as 500 lorries planned for HS2 development
The zoo's ecologists argue that the hedgehogs would be killed if their home is turned into a lorry depot during the building of the new line from London to Birmingham.
The London Zoological Society, which runs Regent's Park, is among more than 820 petitioners to the House of Lords objecting to the HS2 line.
Fay Vass, chief executive of the British Hedgehog Preservation Society, which supports the zoo's objections, told the Mail on Sunday: "It's the only Royal Park with a hedgehog population.
"We support any calls to protect the area they're in from HS2 developments because that's going to impact on that population, which may not be able to re-populate after any work has been done. The best possible solution is for the hedgehogs not to be disturbed at all.
