Question

examples of plants and animals that show positive and negative effect of the fan Menon

Answer 1

Fire can have a positive and negative effect on our plants and animals. We manage fire in national parks to minimise the ecological impact on our wildlife and native vegetation.

Positive effects of fire

Fire is often associated with negative impacts on the environment. We usually think of the damage and devastation fire causes to wildlife and vegetation, but a fire event can also be beneficial for our plants and animals. For example, fire:

heats the soil, cracking seed coats and triggering germination

triggers woody seed pods held in the canopy to open, releasing seed onto a fresh and fertile ash bed

clears thick understorey reducing competition for seedlings

encourages new growth that provides food for many animals

creates hollows in logs and trees that can be used by animals for nesting and shelter.
