Mulching is a forest fuel treatment commonly applied in the WUI to mitigate the risk of wildfire. Mulched fuel treatments attempt to incorporate the following fuel treatment principles: · Retention of larger, healthier stems · Reduction of crown bulk density · Conversion of surface fuels to a less combustible state Mulched fuel beds vary in volume and nature based on: Volume of aerial and surface fuels processed · Equipment type and treatment intensity Mulched fuel bed properties such as depth, compaction and particle size can influence moisture retention, ignition potential and fire behaviour.
