The Tasmanian Government's plan to open up national parks to deer hunting is not a credible way to deal with the harm fallow deer are causing, the Wilderness Society says.

The Government on Wednesday said it would provide access to additional hunting areas by next deer season and include national parks, new sections of the Tasmanian Wilderness World Heritage Area and conservation areas.

It said a statewide deer population census would inform where recreational hunters would be able to legally shoot the animals, and that these areas would not be close to tourist hotspots within the parks.

The Department of Primary Industries, Parks, Water and Environment said hunters could already legally shoot deer in some areas run by Parks and Wildlife and the Government's announcement concerned additional land parcels.

The move is one of many recommendations that came out of last year's Upper House inquiry into Tasmania's wild fallow deer population.

The inquiry found the introduced species had spread hundreds of kilometres across the state from the Midlands, where they are most common, to as far as Southport.

Conservation groups have previously supported a cull, including former Greens leader Bob Brown at one point proposing an aerial cull.

'This is not a proper management strategy'

While the Wilderness Society's Vica Bayley said there was a deer problem in Tasmania, he believed recreational hunting was not a credible solution.

"Absolutely there is a deer problem is Tasmania — they're causing massive damage across both private and public land, including reserve land," he said.

"[But] recreational hunting is not a proper management strategy for dealing with deer or any other feral species."

But senior vice president of the Sporting Shooters Association's Tasmanian branch Donald Ridell said allowing experienced hunters to cull wild fallow deer was a "sensible" option.

"This is a sensible way of going about it — getting people who are familiar with the terrain, familiar with the animals and familiar with what's required [to hunt deer]," he said.

"We welcome the Government looking for a low-cost sensible alternative for managing these deer numbers."

He said there were only small populations of deer in wildlife areas so an aerial cull was not warranted.

Mr Ridell suggested relying on small hunting groups was a sensible approach to deer management.

'It's utterly ridiculous to let this happen'

Animal Liberation Tasmania spokesperson Kristy Algar said national parks were supposed to be places where people could experience nature at its best.

"Suddenly, we're going to have increased numbers of people with guns in national parks and we're going to see animals being slaughtered on a larger scale in national parks," she said.

"It seems utterly ridiculous to be allowing this to happen."

Ms Algar said duck hunting at Moulting Lagoon on Tasmania's east coast was already an issue.

"That is a Ramsar-listed site that for three months of the year can't be enjoyed by recreational people … because it's full of shotguns and duck slaughter," she said.

"To then be saying our national parks can be open to shoot animals, it's unfathomable."
