In the UK "studies" and "trials" are used as a means of delaying meaningful action, frequently in cases where successful trials elsewhere followed by full scale reintroductions have made further work unnecessary. The usual excuse is the UK I s somehow different from Europe.
In the case at hand there is already UK evidence of European Bison effects on a fenced UK landscape at the scale of this "trial", from the Highland Wildlife Park herd. Nothing to be learned, nothing intended to be learned, just an attempt to get funds by lies about reintroductions.
For conservation organisations to endorse this kind of dishonesty plays into the hands of those who are delaying e.g. beaver reintroductions at full scale across England - now long overdue - studies long completed, benefits known - while silly little fenced compounds for the amusement of the super rich are hailed as reintroductions. It's time for straight talking and elimination - public refutation by the guilty - of BS claims of free roaming Bison.
