  1. Aboriginal Fire

  2. No human society has lacked fire Read quote from, Touched by Fire, Stephen J. Pyne (2001)

  3. Key Question:Were western landscapes prior to Euro-American settlement wilderness or modified landscapes by pre-Euro-American peoples?

  4. "Charcoal is the spore of early hominids. The record of their wanderings is preserved and dated by fire." Stephen J. Pyne (2001)

  5. Reasonsfor Aboriginal Burning

  6. Burning for communication

  7. Burning for travel

  8. Burning to protect forests from crown fires and to stimulate vegetation growth

  9. Burning to attract game to new vegetation and drive game

  10. Burning for warfare and hostility towards Euro-Americans

  11. Burning for agriculture and to stimulate desired plants

  12. AboriginalFires Lightning Fires Determining how fires started historically is critical because "fires set by hunter-gathers differ from (lightning) fires in terms of seasonality, frequency, intensity, and ignition patterns" (Lewis 1985).

  13. Opposing Viewpoints Aboriginal Burning Played Major Role in Maintaining Historical Landscapes -Human manipulation of vegetation with fire was present for many millennia before the arrival of Europeans -Humans could start fires at odd times, change biomass, and modify local weather

  14. Oregon's Willamette Valley -Kalapuya Indians burned grasslands every year in fall -Burned for hunting white-tailed deer, harvest tarweed seeds, kill grasshoppers (food), clear brush beneath oak trees, (ease acorn collection), and favor growth of camas, lupine and other wild roots

  15. "…the Americas as first seen by Europeans were not as they had been crafted by God, but as they had been created by native peoples" (Kay 1995) "Despite European images of an untouched Eden, this nature was cultural not virgin, anthropogenic not primeval, and nowhere is this more evident than in the Indian uses of fire" (Krech III, 2000)

  16. Evidence for Native Burning 1. Accounts by early Euro-Americans 2. Oral histories by Native Americans 3. Ecological Fire History Data 4. Pollen/Charcoal Data

  17. Reasons to question reliability of early Euro-American observations of native burning 1. Biased Observers 2. Ignitions not Observed 3. Ignorance of Lightning Burning

  18. Fires set by natives were most common in spring and fall Fires most common in lower-elevation valleys and hunting and travel zones.

  19. Example of people and fire arriving together (top) Queensland, Australia (bottom) Lake La Yeguada in Panama From, Fire, Stephen J. Pyne (2001)

  20. During 1960-1975, 80% of fires on N.F. in AZ and NM were ignited by lightning (avg. 1,873 fires/year)=highest rate of lightning fire ignitions in the US (Barrows 1978)

  21. Example of humans substantially modifying their environment -0.5 ha/person/yr for staple foods -wood for clearing ag. Land, firewood, heating, building materials

  22. "The Turkey Springs area has been the site of human settlements, at least periodically, for several hundreds or even thousands of years..may reflect preponderance of human ignitions" (Romme, 1994)

  23. Ignitions are not limiting factor in the Southwest Climate and Fuels are the primary drivers for fires in the Southwest
