viewfromthehill:We can't ever be 100% safe anywhere, but we can do everything possible to mitigate the risk.
I agree with the first phrase, but can't agree with the second. We can, and should, take all reasonable steps to mitigate the risks but that has to be commensurate with the level of risk and the practicalities on the ground. Where public footpaths are concerned we also have to bow to the opinions of the County Footpaths Officer.
I can only speak as I find from personal experience. We have two footpaths running across our farm. Of a total of ten fields/paddocks, five have a footpath. One runs entirely down the edge of two fields and is often used by people walking small dogs (owners of larger dogs tend to be put off by the fact that every field boundary on this path has a stile). If we had cattle I would be tempted to fence this path along its whole length. When I mentioned this to the County Footpath Officer, although he admitted that he couldn't stop us doing it, he didn't like paths to be fenced off unless there was a very good reason for it. It spoilt the 'experience' of walkers. Given his attitude (you don't really want to upset officialdom unnecessarily) and that it would also make hedge trimming more difficult, we have left this one alone. Incidentally someone has suggested electric fencing. This would get our Footpath Officer very excited indeed!
The second path, as I have said earlier, runs across a small paddock and within six feet of the front of our barn - obviously this cannot be fenced off. Then it goes along a field boundary which we have fenced off then in a dog leg across a small 3 acre field. The reason for this dog leg is not obvious as the field was the same shape in the earliest map in our deeds (1885), but older residents do say that many years ago there was a small stream down the field which has disappeared underground, so maybe the path crossed the stream at the shallowest place. A previous owner of this field created a manège at the point where the path enters and tried, unsuccessfully, to have the path diverted round the edge of the field. To fence this path off would create two virtually useless enclosures.
Both these paths then continue to cross neighbours' land. In the one instance, a mixed beef, sheep and arable farm, which like us reckon almost half their fields a have paths or bridleways. About half of these run along field boundaries some of which have been fenced, most of the rest run diagonally across fields which are used in rotation for barley, beans, grass. When down to grass they are grazed by the suckler herd, the pedigree Lims and sheep. To take these fields out of the grass element of the rotation would be very restrictive for the farm. The other path runs diagonally across a very oddly shaped 10 acre field on a slope and fencing it off would really render the whole field virtually useless. This farm is dairy only. The size, shape and location of the field mean that it is not suitable for cows in milk, silage grass or maize so is used mainly for summer grazing Holstein heifers. This is the only footpath on this farm but there is quite a long bridle path (also used by walkers) which runs mainly along field boundaries, and also straight through the farm yard. This is unfenced.
We are on the edge of a dormitory village in the greenbelt south of Birmingham. These paths are used frequently by local residents, urban visitors and by the scouts and guides from a nearby camping and activity centre. The stock in these fields have grown up with walkers and riders as a fact of life and mostly take no notice of them at all. There have certainly never been any incidents and I'm sure the bush telegraph would have been punctilious in reporting anything remotely scandalous.
If our neighbours are wise they will, in the light of recent publicity, have jotted down a written risk assessment, but I am sure that they would both be perfectly justified in concluding that the risk level is so extremely low that they need to to take little or no action to mitigate it.
