"That's why hunters have put a stake in the ground here."
Doc did not respond yesterday to Hewetson's suggestion.
The foundation has filed judicial review proceedings against the Minister of Conservation and director-general of conservation over the tahr cull.
It is scheduled to be heard in the High Court at Wellington on Wednesday next week.
Hewetson's immediate concern was helicopter shooters beginning the cull before the hearing.
However, Doc operations director Ben Reddiex told the Otago Daily Times yesterday the operational plan had been finalised and approved but the implementation was "subject to operational planning, weather conditions and upcoming legal proceedings".
Dr Reddiex said the plan focused control on stopping the spread of tahr outside its "feral range", protecting and preserving the national parks by taking tahr to " the lowest practicable densities" and controlling high densities of female and juvenile tahr across the feral range.
Game Animal Council chairman Don Hammond yesterday criticised Doc for a "lack of meaningful consultation".
"Only two days was provided for consultation.
"The final plan being released minutes before it comes into effect and with almost no change from the original version indicates a predetermined outcome.
"If the operations are completed, they will devastate tahr hunting in New Zealand."
Hammond said Doc's plan would have "huge impacts" on recreational and commercial hunting "just when we need all the jobs we can muster".
"It is a sad day, not just for hunting in New Zealand but also for the principle of proper consultation by government agencies."
