According to co-ordinator of the Wingecarribee Our Future Environment (WOFE) program Eddie Anderson, the day will give council the chance to draw attention to a number of environmental programs currently underway in the shire.

"There will be a display on the plastic bag-free town program, which comes just after the launch of the re-useable shopping bags in Fitzroy Falls," Mr Anderson said.

"The display will be encouraging other areas of the shire to adopt the program as well as creating further awareness."

Mr Anderson said many local environmental organisations would be represented at the display.

"National Parks and Wildlife will be at the display with their education caravan, as will the Hawkesbury-Nepean Catchment Authority, who will be addressing issues of sediment and erosion control," he said.

"Local Landcare and Bushcare groups will also be putting on displays about the areas of land they have been looking after."

According to Mr Anderson, there will be a strong focus on weed control in this year's displays.

"There will be a display on weed control in the Southern Highlands, which will help raise people's awareness of noxious and environmental weeds in the area," he said.

"The Bushcare and Landcare teams and the Noxious Weeds team have been encouraging landowners to engage in weed control on both agricultural and private land as part of the Noxious Weed Act.

"The Environment Levy has funded weed control in areas such as the Mount Alexandra reserve, Mt Gibraltar, Mittagong Creek, White's Creek, Burrawang and Penrose."

Mr Anderson said there would also be a display on worm farming and composting, and the contribution they make to sustainable living.

"We will have a working worm farm, which will allow people to see what they look like and have their questions answered about then way they operate," he said.

There will also be displays on water and energy conservation and bushland restoration.
