The 2019-20 Black Summer fires saw around 40 per cent (300,000 hectares) of all NSW rainforest burnt. Rainforests are one of Australia's most fire-sensitive vegetation communities, so what are the impacts of events like these fires?
Rainforest plants may not recover as they have no seed banks to help regenerate after the fire
While bigger trees may not die immediately, fire damage to their trunks can allow pathogens that cause disease to thrive
Rainforest fauna cannot thrive as they depend on a moist microclimate
All of the above

They make the soil nice and unstable so it's easier to dig holes
They just look really pretty
They give wildlife food and shelter, improve air quality, maintain soil health and minimise erosion

How does a drier atmosphere impact tree health?
It assists trees in growing stronger and more climbable branches
It helps bring moisture into the tree through its leaves, hydrating and nourishing the plant
It helps trees to thrive by ensuring their trunks don't get too soggy
It draws more moisture out of the tree than it can absorb through its roots, leading to water stress and eventually death
