How do small fires decrease the likelihood of bigger catastrophic fires?
The arrangement of fuel treatment units changes fire behavior by forcing a fire to repeatedly flank around patches of treated fuels, or to burn through them at lower intensity, thus reducing the fire’s overall intensity and growth rate.
What causes forest fires How can forest fires be prevented?
Clear the area around the burn pile of any flammable debris. Keep firefighting equipment handy – a connected water hose or at least five gallons of water and a shovel should be nearby. Don’t burn if it’s too windy to burn – if trees are swaying, flags are extended, or waves appear on open water.

What are positive effects of wildfires?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier. History teaches us that hundreds of years ago forests had fewer, yet larger, healthier trees.
What are the impacts of forest fire?
EFFECT OF FOREST FIRE loss of biodiversity and extinction of plants and animals. loss of wildlife habitat and depletion of wildlife. loss of natural regeneration and reduction in forest cover. global warming.
What are the long term effects of forest fires?
Wildfires can have immediate and long term effects on the quality of rivers, lakes, and streams. 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.
