Sightings of identifiable males located outside of the national parks management unit have also been mapped to help hunters.
"Hunters can head out on trips this summer on public conservation land throughout the feral range knowing DoC's control work for the year is complete."
Next month, DoC will meet with the Tahr Plan Implementation Liaison Group to begin engagement on a Tahr Control Operational Plan for 2021/22.
"We're approaching the development of next year's work programme with an open mind and we're looking forward to reviewing what we have learned over the past couple of years with members of the group," Holborow said.
Between 2016 and Autumn 2019, the tahr population was estimated to be approximately 34,500 on public conservation land alone.
