Bushfire Risk Management in Road Reserves
29 September 2023
Sourced through Creative Commons Fuel Structure • When managing fire, we manage fuel load arrangement and continuity (both horizontal and vertical) Threats to roadside vegetation The long thin nature of road reserves leaves them highly vulnerable to Edge Effects, i.e., increased exposure to: • Traffic, • Increased grazing pressure (livestock, ferals and wildlife), • Light, • Loss of species • Wate. [...] Analysis of reserves in the Wheatbelt by Parsons and Gosper (2011) determined the average time between fires from 1983 to 2004 was: • 339 years in small remnants 100-500 ha • 67 years in large remnant >500ha • 40 years east of the clearing line. [...] • This fast-moving water promotes the growth of weeds, and other bushfire fuels, and is a major cause of soil erosion, it also carries chemicals and other pollutants into nearby wetlands and water supplies. [...] • Nor are they usually carried by it So how do we manage? By addressing the following questions: • What needs to be protected? • What are the actual threats? • What are our biodiversity assets and what are their requirements? • Are our actions and effective and sustainable means of protecting assets? • What are the consequences of our actions? • Can we change our approach and activities? • Are sub.

Will the treatment cause any unacceptable environmental harm, such as affecting rare or protected species or communities? Can these impacts be minimised? 4.
