MOVIE stars behaving like pigs is a common theme in entertainment television and in gossip magazine reports.
But the stars of a new movie produced by the Northern Rivers Catchment Management Authority don't have to turn it on, it's in their nature because they are feral pigs, the real ones with trotters.
And this movie is not a version of the "La La Lah" tale of a cute pink piglet on adventure with Magda Szubanski.
It's the serious business of raising awareness of the ecological damage done by feral pigs and the means of controlling the population.
National Parks and Wildlife Service Pest Management Officer, Lisa Wellman said feral pigs caused considerable environmental damage and the service considered their control to be a high priority.
"Feral pigs are a declared pest and have been recognised as a key threatening process to biodiversity at a national and state level because of the impact they cause from predation, habitat degradation, competition and disease transmission," Ms Wellman said.
"Feral pigs degrade habitat through selective feeding, trampling and rooting for underground parts of plants and invertebrates.
"They are particularly damaging along drainage lines, moist gullies and around swamps and lagoons or after rain, when the ground is softer," she said.
Ms Wellman said a range of techniques are used to control feral pigs including baiting, trapping and aerial culling.
"Feral pig control requires a co-ordinated approach. A number of stakeholders including landowners, the Livestock Health and Pest Authority, local councils, National Parks and Wildlife Service and the Catchment Management Authority have contributed to the movie," she said.
The movie has been produced in five and 20-minute versions.
The five-minute version can be viewed on YouTube.com.
