In the countryside there are issues relating to conflicts between walkers and livestock, and these occasionally result in people being injured or even killed. Dogs often contribute to such conflicts – see in England and Wales The Dogs (Protection of Livestock) Act 1953. Also footpaths in remote locations can be difficult to maintain and a route along a country path can be impeded by ploughing, crops, overgrown vegetation, illegal barriers (including barbed wire), damaged stiles, etc.
