  • Natural is a word we all like to use but what does it mean?
  • Historic accounts tell the story
  • Build up of pine needles and bark around old growth pine
  • Sisters has one of the steepest rain gradients in the world from Santiam Pass to Sisters
  • High elevation forests burn at high intensity
  • B&amp;B Fire 2003 However in the past few summers- this is often been the view we see
  • Formation of a fire scar during the B&amp;B Fire
  • We ’ve looked at Fire History in areas like the Metolius Basin
  • Many of these pink areas have burned
  • We can ’t just let fire burn, but we can place fire lines strategically
  • Lupine on Eyerly Fire 2 years after
  • Eyerly Fire 2002
  • Pole Creek Fire Recovery

As there was no underbrush, these fires consumed nothing but the dead pine needles, cones and twigs… the little blaze only a few inches high crept slowly over the ground… but did no damage whatever to green trees.” Dr Urling Coe, Frontier Doctor
