Document Summary
3 main things = acres burned, structures lost, lives lost. Radiant heat (like a marshmallow turning brown) Convection (updraft in fire, carries hot air and gas and creates fire in canopy/structure) Fire protection services in urban areas people pay through taxes for this. 2 ways to address: urban water, saving lives, wildfire plows, rx lines, planes. Wild-urban interface = area with a heightened human influence and land conversion = changing natural goods and services and management. < or = 19th century = increase in low level fire, open forests. > or = 20th century = more obstacles, catastrophic fires. Wildfires suppressed, fuel loads build = increased risk. 1 answer = reduce vegetation around home. Increase wildlife suppression = increase natural vegetation = now reinforcing. Mechanical treatment thin trees, make mulch, healthy forest initiative , similar harvest for pulpwood. Grazing hard to manage in fragmented areas, nomad goat herd, cows decrease vegetation in tallahassee. Herbicide apply chemicals but not in wui,
