In cemeteries, headstones can often be at threat of becoming Unserviceable. This is often due to trees growing in or near the grave and their roots or branches pushing over the headstone.
It is useful to indicate that a Headstone is "Threatened" so family, or others responsible for maintaining the grave site, can be contacted to take steps to avoid the headstone becoming Unserviceable.
Is a new status needed to indicate this status?
