Roads contribute to declining biodiversity. As an example, roads put pressure on barn owl numbers in certain areas as a result of deaths caused by vehicle strikes. Bats can be affected by road lighting at night and insect pollinators are affected by pollution and poor management of grass verges.

The Highways England Biodiversity plan proposes to include at least five measures to maximise habitat connectivity, linking road verges and associated land with the wider landscape wherever possible. This will include consideration of measures to improve connectivity across roads, which might include green bridges and/or tunnels.
We would love our wildlife to be able to cross roads safely, this will lead to fewer car accidents and increased biodiversity and wildlife in the United Kingdom.
