Hedgehog populations have declined by over 50% in the UK since 2000, and improving garden connectivity by creating hedgehog highways between enclosed gardens is one of the most effective individual actions possible.
Hedgehog welfare in urban areas is severely compromised by garden fragmentation. Individual hedgehogs trapped in enclosed gardens cannot meet foraging requirements, find mates or access suitable hibernation sites. Netting at ground level, ponds without ramps and slug pellets are additional specific threats that can be readily addressed.
