Abstract

Dog walking is among the world's most popular recreational activities,
attracting millions of people to natural areas each year with diverse
benefits to human and canine health. But conservation managers often
ban dog walking from natural areas fearing that wildlife will see dogs
as potential predators and abandon their natural habitats, resulting
in outcry at the restricted access to public land. Arguments are
passionate on both sides and debate has remained subjective and
unresolved because experimental evidence of the ecological impacts of
dog walking has been lacking. Here we show that dog walking in
woodland leads to a 35% reduction in bird diversity and 41% reduction
in abundance, both in areas where dog walking is common and where dogs
are prohibited. These results argue against access by dog walkers to
sensitive conservation areas.
