Yesterday Mr McKim hailed the significance of the state's wetlands and declared it was about time the state's love affair with duck hunting ended.

But Environment Minister Matthew Groom confirmed the pastime would remain in Tasmania for the foreseeable future, calling it a "legitimate recreational activity".

"Tomorrow global celebrations of World Wetlands Day will get under way, recognising the vital role wetlands play in securing 70 per cent of the world's fresh water needed for agriculture, fisheries and drinking water supplies," Mr McKim said.

"Next month will see the opening of the annual duck shooting season, which impacts the state's wetlands, including our Ramsar recognised sites."

"The Greens call on the Environment Minister [Matthew Groom] to not just pay lip-service to our acclaimed wetlands this year, but to take the opportunity to truly celebrate World Wetlands Day by ending the annual slaughter of water fowl."

Mr Groom responded to Mr McKim's concerns yesterday by saying the government had no intention of banning the popular pursuit.

"It is appropriately regulated to ensure it is done safely and sustainably. There are no plans to make any changes," he said.

Mr McKim was not satisfied, however, and also took aim at the state's current coastal policy.

"The best birthday present the Liberals could provide Tasmania's 10 wetlands listed as internationally significant under the Ramsar Convention would be to . . . move on a comprehensive state coastal policy," he said.

The suggestion was noted by Treasurer Peter Gutwein, who stated plans were still in the works for a renewed policy.

"It will be completed in a timely fashion unlike what occurred with Labor and the Greens," he said.
