1. Fires in Nature

2. Global Distribution

3. Which technique is better?

4. Causes
Dry fuel (Drought) – Dry Vegetation. Forests more risky than grassland = More fuel
Vegetation types, eucalyptus contains oil which can explode
Ignition Source –
90% caused by humans
Arson
Unattended campfires
Power line failure
Disguarded cigarettes
Hot lightening strikes
Lava
Climatic conditions for spread – Dry winds from continental interiors

5. How might slopes affect the spread of wildfire?
How might wind affect the spread of wildfire?

6. Trends – Can you describe and explain?

7. Growth In rural population
Increased dry spells (links to climate change)
Increase in power line distribution
Increases in arson linked to transport and social media

8. Firebrands

9. May also be a ground layer in areas of dry peat

Zone 1 extends 30 feet* out from buildings, structures, decks, etc. Remove all dead plants, grass and weeds (vegetation).

15. Zone 2 extends 100 feet out from buildings, structures, decks, etc
Zone 2 extends 100 feet out from buildings, structures, decks, etc.Cut or mow annual grass down to a maximum height of 4 inches.
Create horizontal spacing between shrubs and trees. (See diagram)
