But you bring up some important points- particularly that of the timing of traditional camas harvest vs. timing of fires. I will be looking at that next. As a scientist who works with fire ecology, do you have any information as to temperature gradients in soils during a low-fuel broadcast burn? I read a study in which scientists tested seeds of various plants at temperatures ranging from 40 degrees C to 120 degrees C at 5 degree increments. While this may give a better sample range, I don't think I could come up with the 10,000+ seeds that it would take to replicate the experiment with Camas! Here's what I think, and I would love your input on this: Soil surface temperatures in hot, direct sunlight could reach 40*C so I don't think that temperatures lower than this would provide much fire-relevant data. On the other side, the lethal temperature threshold for most seeds is around 60*C. Do you think I should keep my temperatures within that 40* to 60* range for this experiment, or should I go higher to accommodate for some extreme, previously unknown resilience within Camas seeds?

Think New England apple orchards or Irish potato fields. Camas does not readily spread on its own and its range has become increasingly restricted during the past 400 years (about 200 years in Oregon). Finding a camas patch is like finding a stash of arrowheads when it comes to interpreting pre-white native cultures. This isn't "foraging," it's crop management.</div><div class=""><br class=""></div><div class="">2) Most camas harvest seems to have been done in spring and early summer, as Le suggests, but could be done almost any time of the year. Broadcast burning in the Willamette Valley seems to have started in July some years and peaked in August for harvesting tarweed. Fall burns are more associated with hunting and filbert and acorn harvesting.</div><div class=""><br class=""></div><div class="">3) Camas production is more related to tillage than to fire. Areas that were harvested during a year would have been mostly bare dirt and wouldn't have carried much -- if any -- flame. The seeds are heavy and drop to the ground. A broadcast burn in low fuel loads, such as grasses and tar weed, burns quickly and often barely heats up the surface soil. Seeds and sprouts can usually survive such a burn with no problem. Perhaps the warmth of the fire had a positive influence on seed germination (semi-serotinous).</div><div class=""><br class=""></div><div class="">4) I'm pleased to see you use Le's term "pyroculture."
