The app uses ordnance survey data, I wouldn't use it otherwise.
I will highlight a few of the rules which seem to be ignored, I will ignore the livestock's temprement as this is subjective. Just because a herd of cattle behave in what I construe as aggressive, the farmer may interpret otherwise. And obviously just because a bull looks like a specific breed, doesn't mean it is.
■ Check that fences, gates, stiles etc are safe and fit for their purpose. (As I said some are covered in barbed wire)
■ Check paths are clearly marked so that users do not enter fields without public access. (often the paths go through bushes forcing the walker to go around, and often the signposts have fallen down)
■ A suitable bull sign would be triangular with a yellow background and a black band around the outside. A bull or bull’s head should be shown (black on yellow) on the sign, with supplementary text (also black on yellow) such as ‘bull in field’ if desired. Supplementary text should not suggest that the bull is aggressive, threatening or dangerous (ie avoid words such as ‘beware’ or ‘danger’). (I can supply photos if needed of "Beware, bull in field")
■ Signs should not be displayed, or should be securely covered, when the animals to which they refer are not present in the field or area. Misleading signs which deter the public from exercising their right of responsible access are likely to be regarded as obstruction and should never be used. (often there are no cattle in the fields on which these signs are displayed)
■ Electrified stock fencing used near to public rights of way will also require warning signs located at suitable intervals along its length – generally 50 to 100 m apart. (recently a whole side of the field had no signage regading an electric fence, which was a less used route, but still a ROW)
Whilst this was more of a thought experiment, I don't really think that not "remembering" to do something is a vaild defence in regards the law.
This is not a single farmer that I am singling out, it is endemic when I go roaming. Admittedly some farmers are far better than others. This is why I was interested in what the rules are. For example, we can all accept that they don't need to provide adequate lighting for those walking at night etc. but surely the basics should be covered.
A "Bull in field" notice seems a very loose control on what could be a very dangerous situation. If a person has to traverse the field and the bull attacked them, would it be deemed that the sign was suitable and sufficient? I was genuinely interested. The guidance seems to suggest it would be. I then wonder why it has such a low control allowed compared to other industries. I use the forklift analogy because it has the same implications. You will be struck by a moving object. Admittedly, the forklifts could be seen as safer as the people driving them have been trained not to hit people.
