Logging and Wildfires
Logging of native forests makes them much more flammable and elevates the severity of bushfires when they occur, pushing some species closer to ecological collapse, according to a review of published science by two leading universities. The study found logging increased the severity of forest fires from about 10 years after the trees are extracted with effects lasting more than three decades. Selective logging or thinning can also increase fire risks. It is up to seven times more likely that the canopy in a logged forest will burn compared with an unlogged forest and once the canopy is burnt, it takes a long time for the recovery. The fragmentation of the canopy also results in warmer and drier conditions for the remaining vegetation as litter and the soil desiccate, contributing increased flammability, the paper noted.
