The most noticeable impact of wildfires is stormwater runoff. After the loss of vegetation, the ground's soil becomes hydrophobic and prevents the absorption of water.
How do forest fires affect plants?
Fire intensity affects plant response to fire and is often used in the management of woody species. The bark of older trees and shrubs commonly insulates the plant from the heat of low-intensity fires, but smaller stems and seedlings are killed. High intensity fire, however, can top-kill the larger trees.

What are the negative effect of forest fire and destroying the habitat of animals?
In forests where fire is not a natural disturbance, it can have devastating impacts on forest vertebrates and invertebrates - not only killing them directly, but also leading to longer-term indirect effects such as stress and loss of habitat, territories, shelter and food.
