The NZ Deerstalkers Association (NZDA) has made incorrect and misleading claims on aerial possum control operations, claims OSPRI.
In an unexpected result, scientists encountered more deer in South Westland forest blocks after 1080 drops than before the drops.
They also encountered and saw the same numbers of deer in 1080 drop zones as they did in zones where 1080 was not dropped.
The question, just how much collateral damage does 1080 poison do, could soon be answered through a peer-reviewed study commissioned by the Marlborough branch of the New Zealand Deerstalkers Association.
Recreational and commercial hunters have been asked to identify areas where game herds are at risk ahead of this year's large-scale aerial 1080 operation.
The call comes as the Department of Conservation prepare for the Battle for our Birds, a large-scale aerial 1080 operation to control rats and stoats in response to a beech mast event.
It follows a similar campaign to control rats and stoats on public conservation land in response to a beech mast event due to heavy seedfall in 2014 and will be the largest pest control operation in New Zealand's history.
The biggest ever single 1080 operation in Wairarapa's Aorangi Forest Park is about to go ahead thanks to the collaboration of groups that have traditionally been at loggerheads.
TB Free New Zealand is carrying out the 30,000ha operation in south eastern Wairarapa and even hunters are on board, which is a mark of how far the 1080 debate has progressed.
