I think that enforcing it will be a difficult task. It is that which would worry me rather than the principle of open access. On urban fringes, there are impediments to husbandry because of levels of access. I refer in particular to dogs, vandalism, and so on. Not unnaturally, land use and general amenity suffer.
Risks have to be shouldered in respect of that.
It is almost impossible for private sector managers to police and manage those areas effectively. I noted today that Dr. Miriam Rothschild confirmed that lack of appropriate management is one of the most significant causes of ecological and environmental loss. That has to be considered in the context of lack of management, and the inability to manage the land because there are no means and resources to do so. Simply tightening the regulatory framework misses the target. Part of my land is so full of ticks that grazing is limited.
