Decades of fighting fires has prevented the normal thinning of forests by fire. Now many forests are unnaturally thick, providing more fuel to fires than normal.

Fires are a natural part of Australia's ecosystem, occurring regularly, especially during the hotter months. However, the frequency and intensity of fires can vary from year to year depending on factors like weather conditions and land management practices. Climate change is also increasing the risk of more severe and frequent fires in Australia.
Without frequent ground fires to clear out dead brush, a woodland becomes more susceptible to catastrophic wildfires and forest fires that can completely destroy the forest. However, large forest fires are a natural phenomenon that occur less frequently than small ones.
Frequent fires can disrupt succession in a community by preventing later successional species from becoming established. This can maintain the dominance of early successional species that are adapted to fire, altering the expected trajectory of succession. Additionally, frequent fires can reduce the amount of organic matter and nutrients in the soil, which can further impact the composition and structure of the community.
Fires are frequent in chaparral ecosystems due to the combination of dry, hot conditions, abundant flammable vegetation, and periodic windy weather. Some plant species in the chaparral have adapted to fire and even require it for their seeds to germinate, leading to a cycle of fire and regeneration in these ecosystems. Additionally, human activities such as accidental ignition and land development can also contribute to the frequency of fires in chaparral areas.

Cigarettes have been the cause of thousands of house fires and forest fires over the many decades they have been used.
Temperate woodland and shrubland
House fires can be categorized into several types based on their causes. Common types include kitchen fires, often sparked by unattended cooking or grease; electrical fires, which can result from faulty wiring or overloaded circuits; and heating-related fires, typically caused by space heaters or improper use of fireplaces. Additionally, smoking materials and candles are frequent culprits in residential fires. Each type emphasizes the importance of fire safety and prevention measures in the home.
Certain tree species, like lodgepole pine and jack pine, have adapted to benefit from frequent fires. These trees have serotinous cones that require the intense heat from fires to open and release their seeds, allowing them to regenerate and thrive in fire-prone environments.

Frequent fires can disrupt succession in a community by preventing later successional species from becoming established. This can maintain the dominance of early successional species that are adapted to fire, altering the expected trajectory of succession. Additionally, frequent fires can reduce the amount of organic matter and nutrients in the soil, which can further impact the composition and structure of the community.
The biome that experiences frequent fires is the savanna. Savannas are characterized by a mix of grasses and scattered trees, and their warm, dry climate often leads to seasonal fires, which play a crucial role in maintaining the ecosystem. These fires help to control tree growth, recycle nutrients, and promote the growth of new grass, supporting a diverse array of wildlife. Additionally, fire-adapted species have evolved to thrive in these conditions.

native Australian trees such as eucalyptus which are tough and durable and are able to withstand the frequent fires
