Wildfires & Society

Ambient Smoke- is smoke from a fire that drifts and surrounds entire communities. According to the Arizona Health Department you want to avoid breathing smoke if you can help it. If you are healthy, you usually are not at a major risk from smoke. People at risk include those with heart or lung diseases, children and older adults.

Wildfires & Society

As people move closer and closer to the forest's edge we have to think about the relationship between nature and people. Forest fires threaten homes and communities every year - but are they always a bad thing? What are some things we should think about?

■Create and maintain a defensible space around your home. This space typically extends 30 to 100 feet from your structure and if done correctly can increase the survivability of your home in the event of a wildfire. ■Identify and practice using at least two escape routes from your home. ■Prepare an evacuation checklist. A list of items to include are: ■Critical medications■Important personal papers, photos, etc.■Pet and livestock transport and food■Cell phone, change of clothing, toiletries.■Critical papers & effects in a fire proof safe■flashlight■Emergency contact information

Benefits-Fires clear out space for new grasses to grow, providing food and nutrients to native wildlife-Fires kill disease preying on healthy, established trees-Fire dependency - some trees actually require intense heat for their cones to open. Without fire these trees could not germinate and would begin to die out -ca.gov
