SECTIONS of Mornington Peninsula and Langwarrin parkland will be burned to reduce the mounting risk of fire this summer.

The Department of Sustainability and Environment and Parks Victoria are clearing existing firebreaks, slashing and carrying out manual fuel reduction programs.

Burns are scheduled in three areas of Point Nepean National Park before the end of spring. They are designed to create strategic firebreaks to slow fire spreading into or out of the park.

Three further burns are planned in Purves Road, Arthurs Seat State Park, Greens Bush and Langwarrin Flora and Fauna Reserve.

The State Government has provided an additional $21 million over the next four years to improve fire readiness on public land near Melbourne's suburbs.

DSE acting chief ranger Libby Jude said: "These fire protection works won't stop a fire from starting, but they do greatly reduce the risk of an intense bushfire developing.

"They also give firefighters a big advantage in attacking a fire in its early stages and bringing it under control. While these works have started a bit earlier than usual, they will continue over the summer and be maintained throughout the fire season."

Seasonal DSE staff were employed earlier this year and based at Rosebud to work on the extra fire break clearing and fuel reduction burns. Additional equipment and a slip-on vehicle have been added to the firefighting fleet on the peninsula.
