Hedgehog Population Decline and Conservation Welfare

Hedgehog populations have declined dramatically across Europe, with habitat loss, road deaths, and agricultural intensification driving a welfare and conservation crisis.

Key Facts

UK hedgehog numbers have declined by approximately 75% since the 1950s, from 30 million to fewer than 1 million
Rural hedgehog populations are declining faster than urban populations, driven by agricultural intensification
Road traffic kills an estimated 100,000-200,000 hedgehogs annually in the UK
Hedgehog street connectivity — gaps in garden fences — is a critical factor in urban population viability
The Hedgehog Street campaign has created over 100,000 hedgehog-friendly gardens since 2011
Pesticide use reduces invertebrate prey availability and can directly poison hedgehogs through the food chain

Welfare Considerations

Population decline is a welfare issue as well as a conservation one. As hedgehog numbers fall, remaining individuals face increasing pressure from habitat fragmentation, reduced genetic diversity, and isolation. Hedgehogs killed on roads die traumatically and often slowly. Those who fail to find adequate food face starvation. The collapse of rural hedgehog populations represents millions of animals experiencing degraded welfare and early death over decades. This is not an abstract conservation concern — it represents ongoing, large-scale suffering in familiar animals in our immediate environment.

What You Can Do

Create a 13cm gap at the base of your garden fence to allow hedgehog movement between gardens
Reduce or eliminate pesticide use in your garden to support the invertebrate prey base hedgehogs depend on
Provide supplemental food and fresh water in autumn to support hedgehogs reaching hibernation weight
Check areas carefully before using strimmers or mowers, particularly in undergrowth
Support the Hedgehog Street campaign and register your garden as hedgehog-friendly
Drive carefully at night in residential areas where hedgehogs are most active
